Thicknesser machine. Peculiarities

A thickness planer helps ensure standardization of board thickness. Without it, it’s hard to imagine building a house, bathhouse or utility room. Thanks to this equipment, it is possible to obtain not only a board cut to height, but also to provide it with a smooth outer surface. In the future, such blanks can be used not only for laying the floor, but also as furniture components or in the form of room decoration elements.

Demand for specific woodworking

It is important to consider that a thickness planer, unlike a lathe, milling or drilling equipment is less popular among a wide range of users. Quite expensive models can also take up a significant amount of space. In this case, it is worth correctly assessing the expected need for this product so that it does not stand idle most time in a dusty corner of a garage or workshop.

Thicknesser is one of important installations in carpentry, construction, woodworking and furniture industries

The main task assigned to this woodworking multifunctional device is to give the workpiece with one processed side a given size. In fact, the device relates to a greater extent not to the domestic field of operation, but to serial or small-scale production. As a result, after finishing, the wood will come out in the same size, both curved and straight.

In most cases, operations are carried out automatically with minimal involvement of a specialist. Although thicknessing machines for wood are relevant for factory workshops, they are also found in home workshops.

Important rules must be followed:

• Excessively thin workpieces are not allowed for processing on budget models. Otherwise, vibration occurs, which has an impact Negative influence on the quality of the treated surface.
• The minimum permissible length for a workpiece is the value determined by the sum of the distance from the front to rear feed shaft plus 10 cm.
• When cutting short workpieces, they must be securely fixed to the work surface.
• To process wedge blanks, you need to use the appropriate device.

The height of the allowance removed per pass ranges from 1-3 mm, and depends on the width of the material. Optimal width processing for domestic conditions is 30-300 mm. For a home workshop, a planer planer with a capacity of 1.8-1.9 kW is sufficient.

High power (from 2 kW and above) will be in demand only for frequent processing of hard wood, which includes beech, pear, ash, elm, etc.

Design features

The vast majority of models are essentially identical designs with different performance. A highly specialized thicknessing machine for wood is not relevant in everyday life, but it can be successfully replaced by a universal specimen with the following equipment:

• electric motor with a power of 1500 W, operating from a 220 V household network;
• a shaft with grooves in which the knives are fixed;
• drum feeding system;
• welded rigid frame;
• table top with extenders;
• block for start and stop;
• adjustment unit with dials and rulers.

What does a plane consist of - mandatory structural elements

It is worth choosing a jointing thicknessing machine based on various parameters, including its external dimensions. In a small workshop, handling massive equipment will be inconvenient and unsafe.

It is preferable to opt for a thicknessing machine with smooth adjustments, which will be more accurate than the stepped type. When purchasing from an online store or hardware store, you should check to see if there is an automatic feeding option. It significantly simplifies the use of this equipment. The processing speed of workpieces also increases. Most models of the latest generations have machines with automatic feed, even at a budget price.

It is worth paying attention to devices with the function of cutting large allowances. This will expand the possibilities of using surface planers.

Types of woodworking machine park

Manufacturers strive to improve the performance of their product. The main emphasis is on the simultaneous processing of several surfaces. Based on this, in store windows there are following types executions:

Unilateral. Capable of cutting chips during processing from only one side of the workpiece.

Double sided. This wood thicknesser is designed to cut chips parallel on both sides - top and bottom.

Multilateral. This type is extremely rare and is not used in everyday life due to the complexity of setup, operation and maintenance. The demand for simultaneous planing of workpieces on three and four sides is minimal.

Most often, in a home workshop there is a single-sided thickness planer equipped with one drum with knives. Its advantages include the following qualities:

• ease of setup and maintenance;
• small dimensions with sufficient performance;
• reduced energy consumption compared to machines that process more sides at the same time.

Smart choice

Conventionally, for comparison, we can divide thicknessing machines for wood into several groups based on performance characteristics. Each batch will satisfy the owners' requirements:

1. You can perform a small amount of work for a country house or cottage using budget or universal models. Such a combined multifunctional device, with some reconfigurations, can easily turn from a surface planer into a planer, circular saw, milling equipment. These include Stark CWM-2500 or BELMASH MOGILEV 2.4. However, for industrial use this type not relevant.

1. If during construction it is necessary to process a significant volume of workpieces, then worthy of attention There will be models like JET JWP-12, Corvette 21.22, Caliber RR-1200. Such models will quickly justify their relatively low price during the construction of their home.

1. Semi-professional equipment with high productivity is recommended for carpentry teams. It is relevant for low-rise construction or for carpentry workshops. Makita 2012 NB, Metabo DH 330, DeWalt DW 733, etc. have positive reviews.

1. Furniture factories are interested professional equipment capable of processing quickly large parties. Analogues in this situation are JET JWP-201 HH.

1. Industrial sawmills or logging plants require narrow-profile machines such as SCM Logic 23, MV 1013A.

Current Selection Options

When choosing a household machine for your own needs, you need to pay attention to its operational parameters. In some situations it is important to buy a thicknesser with a “margin of safety”, but this often leads to unnecessary expenses financial and energy, which may not be useful in the future.

You need to pay attention to the following values:

• Dimensions. The larger they are, the larger the workpiece can be passed through the working area.
• Depth of cut. The knives can only remove a limited height at a time, but the larger the cut, the more powerful the electric motor is required.
• Motor power. A too weak engine forces you to achieve the required height in several approaches.
• Rotation speed of the working shaft. The faster the rotation, the cleaner and smoother the surface of the workpiece and the faster you can pull the beam.
• Noise level - in some cases this is of fundamental importance. The lowest threshold is shown by equipment manufactured by Makita.

When purchasing, you should take care of purchasing a spare set of knives.

Thicknessers are often used in construction industry for processing wood parts different breeds. The machines are designed to give workpieces the desired size and shape. With their help, boards or timber of a certain thickness and width are obtained.

The design features of the machine allow you to process parts or obtain finished goods with the required parameters with millimeter precision. Using a thicknesser, you can plan workpieces in one plane, adjusting the thickness of the board. The workpiece being processed is guided through a special mechanism that simplifies the operation of the machine.

The design of the thicknesser consists of a motor with a knife shaft attached to it, there is also an adjacent working surface and special rollers.

Thicknessing machines are used for processing wooden elements and manufacturing of products in industrial scale. Some types of such equipment can also be used for domestic purposes.

Different machines have certain design features , differ in the power of the operating equipment and the specifics of the work performed. Maximum speed shaft rotation may also differ depending on different models surface planers. The dimensions of the machine, the depth of the cut made with its help, and the width of the cut also differ for machines of different types and sizes, depending on their functionality.

The equivalent cost of machines of one type or another also differs from each other: more powerful models, which have the widest range of tasks to be solved and methods of processing parts, as well as larger machines, cost much more than small, cheaper budget mechanisms for wood processing.

Operation

Typically, processing materials using a surface planer involves planing wooden blanks and parts having a length slightly bigger size than the length of the distance established between the rollers.

Thicknesser works using flat planing method, subjected to processing of the material. In this case, the processing of a wooden workpiece is carried out due to the work of the following elements:

1. Knife shaft. The knife shaft included in the design of the thicknesser performs the main function when processing the workpiece.
2. Rollers. The parts are fed to the surface of the work table under the action of installed rollers.

The part is fixed on the working surface using a special mechanism, which ensures the most accurate processing. After this, the part is planed using knife blades acting on it from above.

This is what happens calibration of the required size of parts, which allows you to make them absolutely identical in size and give them the same shape. If the thicknesser has an automatic feed mechanism, then the speed required for drawing parts can be adjusted.

When used during processing of special overlay parts with the help of such a machine, it is possible to plan materials that have oppositely located non-parallel edges. In this case, it is necessary to install the parts, giving them a certain angle of inclination.

Carrying out work on processing parts using such equipment provides the opportunity get highest quality . In addition, by processing lumber on a surface planer, you can perform the work in the most accurate manner, regardless of total number parts used.

Thicknessers are very economical woodworking equipment in terms of its maintenance, which differs high level productivity.

The operating mechanism used allows processing lumber up to one meter wide and a little more. In this case, the greatest depth of the cut produced is usually 145-155 mm and even more, depending on the model used.

Types of equipment

There are various surface planers:

Depending on the type of design, surface thicknessers can be classified into the following devices:

1. Mobile. They are light in weight and size. Such compact devices can be used for planing small workpieces.
2. Stationary devices. They are distinguished by their impressive size and heavy weight. Large surface thicknessers are used for processing large parts.

Regardless of the component parts and functional purpose, all machines are equipped special device, providing automatic feeding blanks. It consists of a system of rollers with the help of which lumber is pressed against a special shaft. The rollers gradually advance the workpiece until it reaches the working surface of the surface planer.

The power of the equipment used varies ranging from 1.6 to 8 kW. When planing, the width can reach 39 cm and the depth is approximately 3 mm.

The machines differ in shaft rotation speed, the number of knives in their composition, the amount of energy consumed and other significant features that must be taken into account when purchasing thicknessing equipment.

Types of thicknessing machines

At in different ways processing thicknessers are divided into several types.

The work of a surface planer differs from conventional jointing in that, as a result of using such a woodworking device, workpieces of the required size and in any quantities can be processed. The texture of the lumber used will be the smoothest, without any damage to the surfaces.

Planing equipment

Reismus similar type used in the manufacture wooden products and lumber that requires the greatest precision, free from the slightest external damage and defects.

Planing-thicknessing machines are capable of creating the most even surface of workpieces. A reduction in thickness during such processing occurs when using the longitudinal planing method. Thus, the details are given desired shape and required dimensions.

When processing lumber with a planer-thicknesser machine, you can also eliminate possible defects wooden blanks (knots, hitches, various irregularities, etc.). Reciprocating movements during operation of the machine are carried out due to rotation of the knife shaft or movement of the workpiece, firmly held by rollers.

Thickness planing machines are produced both domestic and import companies . Thanks to the wide range of products, it is possible to choose a model of such a machine for use for various purposes: in everyday life, as equipment for a home workshop. You can purchase more powerful units to equip a wood processing workshop and use them in production.

Thicknessers for home purposes

Machines used for domestic purposes have the following characteristics:

Thicknessers used for household purposes are equipped manual parts feeding system. They are not used to cut through the surface of the product as deeply as possible. Since such machines require certain physical inputs, they are not used to perform labor-intensive work or when working with large quantities of lumber.

Production devices

Thicknessers used for industrial purposes require the organization of a special place for their installation. The lumber is fed into them automatically. They operate using power from the network.

Industrial thicknessers have great power, therefore, for proper and long-term operation they are additionally equipped with the necessary built-in cooling system.

They are characterized by the presence of the following functions:

• maximum power;
• high planing speed;
• the ability to make deep cuts of parts and workpieces.

The knives of such machines can be located on both sides or on top. The machine also has a rotating drum and a double stand in its design.

Production thicknessers are equipped with a special device that controls its operation, making it possible to set the required cutting depth.

Criterias of choice

Today the market for such machines is filled with equipment various types. You can purchase planer-thicknesser or planer-thicknesser machines as Russian production, and made in Japan or China.

Models produced in some European countries are also widely represented. When planning to purchase a surface planer for various purposes, be sure to pay attention to the following factors:

1. The quality of its workmanship and functional features machine
2. The purpose for which the machine is purchased. If you need to process parts for your home, you don’t need to purchase expensive models. It is quite possible to use compact budget options.

Thicknesser is a widespread type of planer that has found practical use in the woodworking industry. Using this machine, beams and boards are planed, but after mandatory processing with a jointer. The processing thickness of the material is adjustable.

What is a thicknesser

Thickness gauge or surface gauge is a tool for drawing marking lines on a workpiece parallel to the selected baseline, or for transferring dimensions from drawings to the workpiece.

Usually it is a stand with a clamp in which the scriber is fixed.

Thicknessers can be made of hardwood and are a block with a rectangular hole in which one or two slats are secured using a wedge or screw. At one end of the slats there are pointed metal pins. A thicknesser with two slats is used, for example, for marking tenons and sockets for them in carpentry.

To simultaneously draw a larger number of lines or in cases where there is no need to change dimensions, a bracket can be used instead of a thicknesser. The bracket is wooden block with a ledge into which is hammered required amount nails

Planing thicknessing machines are:

One-sided;

Two-sided.

The first type of machines is distinguished by the fact that their knife shaft processes the material on one side. Machines of the second type process the workpiece in parallel from the top and bottom sides.

The engine power of such machines can range from 1 to 44 kW. The processing width reaches 135 cm, and the thickness varies from 0.5 to 16 cm. The machine shafts have diameters from 10 to 16.5 cm. Each shaft can have from 2 to 4 knives.

The range of such machines on the market is quite wide. It is represented by both foreign and domestic models, which are similar in basic characteristics. However, the functionality of foreign models, their strength and reliability are usually higher in comparison with machine tools domestic production. But the price of our machines is lower than their foreign analogues. The cheapest thicknessing machines are Chinese-made models.

We focus on the fact that in 80% of cases the reviews regarding machines manufactured in Europe are positive, in our country - in 50% and in China - only in 30% of cases.

Thicknessers are becoming increasingly popular. These portable machines provide perfect surfaces and millimeter precision. But can they be called a true planing all-rounder?

Purpose of a surface planer

Calibration of boards by thickness. What is a thicknesser and what is it for? A thickness planer is a machine (portable or massive stationary) designed for finishing planing of boards to a given thickness. The thicknesser passes the board through itself, planing the upper surface with a wide shaft with blades. At the exit the user receives a board required thickness with a flat smooth surface. Thicknessers are in demand primarily in carpentry, as they allow you to calibrate workpieces for flush joints: parts of the same thickness form a flat surface. It is important to understand that a thickness planer does not make straight boards out of curved ones; its purpose is to ensure right size. In this case, at least one side of the workpiece must be flat initially.

Planer design

Adjustment mechanism, automatic feed. Thicknessers are equipped with a powerful motor, which, using a belt drive, rotates the shaft with knives. The upper part of the machine is movable and runs along vertical guides. To set the desired thickness of the board, use a setting mechanism with millimeter and inch scales.
Most machines have automatic feed of the workpiece: two rollers (in front of the knife shaft and behind it) move the board at a speed of about 7-8 meters per minute. The user is required to place the workpiece on the table, feed it into the machine and receive it with reverse side. This feature is very useful as it saves energy. Some models have two automatic feed speeds: high ensures fast work, and low allows you to get the highest quality surface.

Specifications

Power, workpiece dimensions, weight. The power of surface planers is usually 1500-1800 W. The planing width and maximum thickness of the workpiece is a kind of thickness planer gauge. These characteristics describe the permissible dimensions of the board. The maximum width, as a rule, is 310-330 mm, and thickness - 150-152 mm. By the way, the maximum thickness shows how wide a board you can process if you place it on its edge. The given figures, of course, do not mean that the surface planer is intended for planing very massive long boards (the machine cannot even drag them through). The optimal caliber of a thickness planer is relatively small workpieces.

In the photo: thickness planer P13F from Hitachi.

Planing depth shows how much wood the machine can remove at a time. For thicknessers, the maximum depth reaches 3-3.2 mm. Please note: it is not recommended to plan wide boards with maximum depth - the wider the workpiece, the less should be removed from it in one pass.
Knife shaft rotation speed for thicknessers it is in the range from 8000 to 10000 rpm. The higher the speed, the better the quality of the planed surface. However, in practice, the quality of processing depends on a number of factors.

The original meaning of the word "reismus" ("reismas") defines a marking tool, however, in Lately the term is increasingly used to refer to representatives of a broad class of equipment - surface planers. In this article we are talking specifically about marking thicknessers.

A marking thicknesser is a tool designed for taking measurements and drawing (drawing) marking lines parallel to the base lines in the process of preparing products for processing. A thicknesser is also used when transferring dimensions to a workpiece from drawings, measuring instruments, or from already processed reference products.

The structural basis of most marking thicknessers is a stand (rod, in the case of a height planer) and a clamp, which can be moved and fixed in different positions on the stand (rod).

Types of surface planers

There are quite a few types of surface planers, and the applicability and capabilities of a particular tool are most often not limited to just one type of material being processed. Nevertheless, it is still accepted to divide thicknessers into carpentry thicknessers (used in wood processing) and metalworking thicknessers (used in metalworking).

Carpenter's marking thicknesser

In the classic version, a surface thicknesser used in woodworking consists of a block with a smooth flat surface, on which two through holes with movable bars (slats) are located perpendicular to the plane. At one end of each bar in the transverse direction there are sharp metal scriber pins (pins, needles), which directly scratch lines along the material of the workpiece. Both racks usually have a rectangular cross-section, which prevents them from turning in the rectangular holes of the block. The size is fixed in the block using a wedge inserted with tension into the hole of the block, between and perpendicular to the holes with the slats, thus reliably holding them from arbitrary movement.

The main elements of a carpentry thicknesser, except for scribers, can be made of wood. In order to prevent rapid tool wear, hard wood is used in the process of marking workpieces. In addition to wood raw materials, hard plastic components and even metal have recently been increasingly used for the manufacture of carpentry planer parts, which significantly extend the service life of marking tools without losing their accuracy due to wear.

In woodworking, a two-rack marking thicknesser is used, in particular, for marking tenon joints, significantly reducing the time spent on preparatory marking work before machining grooves, nests and tenons.

While maintaining the key features, there are still designs of carpentry thicknesser that differ from the classic one, which in itself is quite universal, which can be implemented in more specialized tools of this type. For example, intended for processing any one class of products, or for very large workpieces, or vice versa, small parts.

A special case of simplifying the design of a carpentry thicknesser can be considered the use of a bracket as a bracket - a solid wooden device with a recess as a step-stop, as well as one, two, or several small nails that act as a scriber, and hammered (inserted tightly into the holes) into specified distance from the stop. In the absence of a ready-made carpentry marking plane, you can make the bracket yourself using simple tools such as a saw, hammer, ruler, pencil. The clamp is convenient to use if you need to draw many parallel lines without changing the distance between them.

Thickness gauges, the block of which sometimes has not two, but only one, have also become widespread. through hole, with a rod (stand) located in it round section. At the end of the rod, a scriber in the form of a washer-blade with a sharp edge along the entire circumference is fixed (with a screw). The post is conveniently clamped with a bolt or screw with a grooved head, the threaded part of which is screwed into the block through a threaded hole, the axis of which intersects at an angle of 90° the axis of the main hole where the rod is located. A similar thicknesser is made from materials such as wood, plastics (including laminated ones), metals or combinations thereof. However, the design with one cylindrical rod as a whole rather expands the scope of applicability of the tool rather than making it highly specialized.

Instead of pointed metal scriber pins, some models of carpentry thicknessers use a pencil for marking, for which an appropriate fastening is provided.

Bench thicknesser

Unlike a tool for marking wooden workpieces, a classic bench thicknesser has a mostly single stand and is motionless, although it can be installed at an angle (but without longitudinal movement in any hole, as is implemented in carpentry tools).

The stand is mounted on a base with a flat surface. The long rod of the scriber is pointed at both ends, one of which has a curved tip. The scriber is secured with a screw in one of the holes in the clamp. The second hole of the clamp covers the stand. Accordingly, the size is set by moving the clamp along the stand, as well as changing the position of the scriber.

The height gauge can also be classified as a metalwork gauge (shtangen gauge), in which the stand is a rod with rectangular cross-section, or is made in the form of two separate parallel rods, and in any case, rotation of the clamp (bracket) around the rack is excluded. The height gauge can be equipped as simple devices reading, such as a vernier with a linear or circular scale, and digital indicators.

Using a marking thicknesser

Regardless of the design of the surface planer, although its use in practice may have a number of specific differences, in general, the setup and basic marking techniques are similar in different types and models.

On any surface planer, the dimensions are first set, which consists of adjusting the distance between the sharp end(s) of the scriber/pencil and the plane of the block or base. After which the lines are drawn directly.

Perhaps the only key difference is that with a carpenter's thicknesser, the plane of the block, when applying marking lines, slides along the surface of the part, while when using bench thicknessers (including height gauges), the base moves along the surface of the plate on which it is installed. marked workpiece.

When marking, it is necessary to limit the mobility of the workpieces. For example, before using a carpentry thicknesser, you can rest the board being processed with your hand against the wedge of the workbench, or use clamps.

I would like to mention that a thicknesser, especially one equipped with a reference device, can be used not only for marking, but also as a measuring tool, for example, for control clarification of intended lines or measurements of distances between already processed elements of a product.

The accuracy of thickness measurements depends on the reference device used. A height gauge with a vernier mechanism can take measurements with an accuracy of 0.05-0.10 mm. For circular scales - 0.02-0.05 mm. For digital devices - 0.01-0.05 mm. For carpentry thicknessers, the linear scale divisions often have divisions of 1 or even 2 mm.

The use of a thicknesser makes work easier and significantly increases productivity technological process by reducing the time allocated for marking. An important point There is also an improvement in the quality of products due to, on average, greater marking accuracy, especially if you use the recommendation to apply marks, if possible, from the same base surface.
