CNC machine for drilling holes. CNC drilling machine
Drilling machines perform the task of drilling a variety of parts, which will then be used to assemble larger mechanisms.
Drilling machines make it very easy to process parts. IN modern world You can find coordinate boring, radial-vertical, radial-grooving and many other types of machines.
1.1 Features of CNC machines
Besides large quantity Although standard drilling machines have advantages, they also have their disadvantages. First of all, they relate to the fact that this equipment is quite cumbersome, and It is extremely difficult to control its movement.
Most spindles, if we are talking about a homemade horizontal drilling, grooving or homemade radial drilling machine, are either in a completely stationary or partially movable position.
That is, they can only be partially controlled. Nevertheless, the movement of parts is carried out manually, due to the rotation of the table, if such a characteristic is present on it, or the movement of the fixing elements themselves.
Moreover, if you do not use a coordinate-oriented table, you will have to work almost by eye, and this also takes time, especially for beginners.
Such poor functionality in terms of efficient movement of parts could not go unnoticed, which led to the emergence of CNC machines.
Currently, CNC stands for “Computer Numerical Control.” This is a special module that is capable of reading commands and transmitting them to working equipment.
However, there are different CNC models. Some models are intended for general use (for example, drilling in wood), while others are ideal when a person needs to process parts on a machine.
Installed on table machineCNC allows you to customize the movement of its elements. The movements themselves are carried out by movable bars, shaft screws, etc.
Different models of such equipment move differently. CNC boring machines only move the workpiece and the spindle itself, but only in one plane. However, boring machines should not provide more than that, because their tasks are quite trivial.
Horizontal CNC grooving machine, although such models are quite rare, more features To move it, it is given to a supporting table.
Radial-drilling machine models, in particular 2Р135Ф2, as well as their other radial-vertical CNC similarities, are fully revealed. In such equipment, almost all elements are subject to movement.
If CNC boring machines are capable of controlling their parts in almost one plane, then radial drilling machines can already change the position of the spindle, table, its elements, etc. Of course, moving absolutely all the parts is not required.
For example, if a radial drilling machine can move the table along the X and Y axes, then it only needs to adjust the height of the spindle, but moving it itself is no longer necessary.
As you yourself understand, a horizontal desktop CNC machine is almost impossible to find these days, and creating a homemade prototype of such equipment with your own hands is extremely difficult. However, this is quite normal, because the equipment used for high-precision metal processing cannot have a simple design.
The same model of the 2R135F2 machine consists of huge amount parts, but this is a relatively simple mechanism when compared with modern coordinate-drilling models.
2 Operating principle of CNC equipment
The operating algorithm of a CNC machine can be described in a few simple sentences.
His work lays down the principles of calculating coordinates in a given plane. Outdated CNC controls, such as those installed on the 2R135F2 machine, are not particularly complex.
It's more likely computing machines than computers. It either doesn't equipped with processors and powerful computing equipment, or are only partially equipped with them.
However, this is more than enough. To read information in outdated models, punched paper tape is most often used. For example, eight-row punched paper tape on a 2R135F2 machine. Nowadays, such equipment primarily reads digital media.
Functioning algorithm:
- The worker determines the coordinates of the location of the part.
- Data is entered into the CNC. Data is entered sequentially, point by point.
- The process of calculating the trajectory of movement and work starts.
- Everything is customizable necessary elements on the machine, working drills are fixed.
- The machine starts working.
- By moving the spindle or table, the work element moves to the desired point and performs its task.
- After completion, the CNC goes into standby mode, requesting an algorithm for its subsequent actions.
Work specifics different models machines will be different. The same boring patterns will differ significantly in their type of movement and manipulation with working tools, but general principle the actions remain the same.
The movement of elements occurs mechanically, due to manipulations with slats, screws, etc. But the commands to them are given electronically, and all calculations are carried out by computers.
2.1 Creating a homemade CNC machine
It’s not for nothing that the hands of craftsmen are called golden, because many inventors have learned to create machines with their own hands that work exactly the same as modern CNC units.
Of course, homemade a mechanism of this type will be inferior to the factory one. And the characteristics of its actions will be far from ideal, but such prefabricated machines can still be used for working on metal, wood, etc.
Most of the hassle during assembly homemade machine appears when it is necessary to create a replacement for the basic CNC, as well as the manipulation bars that move the horizontal tool in conjunction with the computers.
For these purposes use:
- Modern computers;
- Special software;
- Small processors for issuing simple commands;
- Special strips and translators removed from printers.
A program is set on the computer, and it also calculates the entire work process. Then it is connected to the system, with parameters already set in advance. Moreover, you will also need to mark the coordinates on the table.
Due to direct or indirect transmission of commands, manipulation is carried out movement of the working element. And the element itself moves on slats, which gives it the ability to move in three planes.
You can assemble the slats and the moving engine yourself (this is extremely difficult, but possible), or you can remove them from printers or other similar equipment and adapt them for personal needs.
2.2 Creating a homemade CNC machine (video)
A CNC drilling machine is a software-controlled equipment for creating and processing holes in body and flat parts made of various materials.
List of synonyms:
- CNC drilling machine;
- Drilling machine;
- Automatic drilling machine;
- CNC drilling equipment.
The machines of the drilling and boring group have universal capabilities and work with a wide range of shaping cutting tools (drills, taps, etc.). This allows you to perform such technological operations as:
Main and auxiliary tool for drilling equipment
Drilling- creation of through and semi-through holes in workpieces using translational-rotational motion cutting tool. A wide selection of drill diameters and the materials from which they are made allows the use of drilling machines to work with surfaces of almost any density.
Countersinking (boring)- semi-finish processing drilled holes with help special tool(countersink). The operation is carried out to increase the diameter and improve the quality of the inner surface of the drilled holes.
Deployment- a process similar in purpose to countersinking. Used for finishing, i.e. final processing holes. The reamer removes metal in small layers (0.02-0.4 mm), as a result of which the accuracy, smoothness and correctness of the hole shape become ideal.
Cutting internal thread - an operation that is performed using taps for further threaded connection blanks A tap is a rod-shaped tool made of carbide steel with pointed grooves, which, when the device rotates, cuts a thread on the inner wall of the hole.
Unlike manually controlled machines, drilling equipment with a CNC system has a number of advantages:
- increased accuracy of drilling holes;
- high speed of work;
- predictability of the duration and completion time of the work process;
- minimizing defects.
Due to the high quality and economic indicators, without software-controlled drilling equipment, not a single medium- and large-scale production industrial production. Drilling and boring machines can be found in all production and repair and assembly shops, in particular:
- at enterprises aviation industry;
- in mechanical engineering and shipbuilding;
- in the machine tool sector;
- in the instrument-making industry.
Classification of CNC drilling equipment
CNC drilling machine
With all the variety of models, automatic drilling machines can be classified according to several important parameters:
Spindle head position
- vertical - the bed with the spindle head is located vertically relative to the table. The most convenient, multifunctional and frequently used type of drilling machines. Most models have a rotating working head with the ability to simultaneously install several cutting tools. The drilling diameter on such machines can reach up to 75 mm.
- radial - the most complex and multifunctional machines, allowing you to process workpieces in three planes. The spindle head is located on a traverse, which moves freely in vertical plane. In this case, the supporting column of the machine can rotate 360 degrees.
Degree of versatility
- special - they perform only one or two operations in a certain type of workpiece and, as a rule, cannot be reconfigured to perform other work;
- specialized - equipment that allows you to perform a limited number of simultaneous operations in certain types of workpieces. Most often they are used for deep drilling, but they can also perform other manipulations, as they are equipped with a large number of tools and devices.
- universal - the most common machines in mass production. They work with a wide range of metal operations: drilling, countersinking, countersinking, creating left- and right-handed threads, etc.
Number of spindles
- single-spindle - for working with one tool;
- multi-spindle - for step-by-step processing of holes various tools, which starts working automatically, without wasting time on manual replacement.
Machines can also be classified by table mobility, maximum drilling diameter (up to 75 mm), spindle speed (2000 - 3000 rpm), etc.

- Column
- Cross table
On the base (bed) 1 of the machine there are slides 2 of the cross table, which has telescopic protection for the guides. A spindle head moves along the vertical guides of the column, on which a six-spindle turret head is mounted, allowing automatic tool change according to a control program. To speed up manual tool replacement, a special pressing device is provided in the turret. The machine can be controlled from a pendant control panel.
Movements in the machine
- The main movement is the rotation of the spindle with the tool
- Movement along the machine axes:
- X-axis - longitudinal feed - longitudinal movement of the table along the slide guides
- Y axis - cross feed - lateral movement slide along the bed guides
- Z axis - vertical feed - vertical movement of the spindle head (support) along the rack guides
- Auxiliary movements - accelerated movement of the caliper, periodic rotation of the turret, precise and accelerated movements of the table and slide (positioning movement).
To control table movements (X and Y coordinates) from a program recorded on punched tape, the machines are equipped various devices CNC (one of the most common is CNC “Coordinate S-70”). Feed along the Z coordinate is carried out in cyclic control mode. For coordinate movements of the table, manual data entry on the CNC console can also be used. The presence of a digital display allows you to visually monitor the position of the table, as well as monitor the correctness of the program recording on punched tape.
The machines provide feedback on the position of the working bodies on each of the two movements controlled by the punched tape. Circular electrical contact code converters are used as feedback sensors. Movements of the turret head during fast and working strokes in both directions are limited by adjustable cams acting on switches (electric stops).
Kinematic diagram of the drilling machine 2Р135Ф2-1
Kinematic diagram of the drilling machine 2р135ф2-1 with CNC 2П32-3
The kinematic diagram of the machine (Fig. 4.6) consists of the following independent kinematic chains: main movement drive (rotation of the turret spindles); cross table feed drive; caliper drive with turret head; turning the turret head; pressing tools out of spindles.
Main movement chain
Main movement chain: two-speed asynchronous electric motor M1 (N=4/4.5 kW; n = 1470/990 rpm) - gear transmission 29/41-shaft I - shaft II (through gears 24/48 and 36/36 with clutches M1 and M2 engaged or through gear 14/36 with the M3 clutch engaged) -shaft III (via gears 14/36 and 48/24 with the M4 and M5 clutches engaged) -shaft V through a bevel gear 21/21 - to one of the turret spindles through gears 35/ 42; 31/49; 49/47; 47/35.
Cross table feed drive chain
The feed drive chain of the cross table has two gearboxes, one of which moves the table along the slide (X-axis), and the second drives the movement of the slide along the frame (Y-axis).
Kinematic chain of the slide drive
The kinematic chain of the slide drive ensures their fast, medium and slow movements. Fast movement (at a speed of 7000 mm/min): electric motor M4 (N=0.6 kW; p=1380 rpm) - gears 16/40; 34/22; 22/52; 52/34 - ball screw.
Moving with average speed(200 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 38/42; 22/52; 52/34 - ball screw. Slow movement (speed 50 mm/min): M4 electric motor - 16/64 gears; 25/55; 25/55; 16/64; 22/52; 52/34 - ball screw. A feedback sensor is mounted on the ball screw.
The table moves along the slide from the M5 electric motor (N = 0.6 kW; n = 1380 rpm); the kinematic chain of the drive of this movement is similar to the kinematic chain of the drive of the slide movement.
Turret Caliper Drive Chain
Turret caliper drive chain: M2 electric motor direct current(N = l.3 kW; n = 50..2600 rpm) - gear 13/86 (or gear 37/37 - worm gear 4/25 - lead screw, equipped with a brake clutch (preventing arbitrary lowering of the caliper when the electric motor is turned off) and a remote control feedback sensor.
Turret rotation drive chain
Turret head rotation drive chain: M3 electric motor (N=0.7/0.9 kW; n= 1400..2700 rpm) - 23/57 gear - 1/28 worm gear - 16/58 gear - turret body .
Pressing tools out of spindles
Pressing tools out of spindles: M3 electric motor - 18/52 gear (with the clutch engaged) - 1/28 worm gear - 21/21 gear - eccentric mounted in the groove of the turret head rotation axis and pressing tool.
Lubricating the turret support
Lubrication of the turret head support is carried out forcibly according to the following scheme: MZ electric motor - 18/52 gears; 52/75 - EZ eccentric, driving the plunger pump.
Gearbox lubrication
The gearbox is lubricated by a gear pump driven by the gearbox electric motor through V-belt. The oil supplied by the pump enters the distribution chamber, where it is distributed to lubricate all moving parts of the gearbox and electromagnetic clutches, and then drained into the reservoir. The oil level is controlled by an oil indicator.
Lubrication of caliper feed gearboxes and cross table
Lubrication of the caliper feed gearboxes and the cross table is carried out by spraying oil onto the gears. The oil level is monitored visually using oil indicators.
Lubricating the guides and screw pairs of the cross table
The guides and screw pairs of the cross table are lubricated manually using a lubricator. The bearings of the turret spindles are lubricated with grease.
Coolant supply
The coolant is supplied from a centrifugal pump. To cool the tool in the cutting zone, an individual drive is provided, which allows you to direct a stream of coolant to the desired location. The supply of coolant in the automatic cycle begins when the caliper moves down (the beginning of the working feed) and stops when the caliper begins to return to its original position (in this case, the corresponding toggle switch must be turned on on the control panel).
Electrical equipment of the machine
The electrical equipment of the machine consists of a separate cabinet of relay automation and CNC, as well as elements installed directly on the machine. Electrical connections between the machine components and the CNC are made of bundles in metal hoses ending with connectors.
Electrical diagram The machine provides the following operating modes:
- commissioning;
- semi-automatic with task input from CNC switches;
- semi-automatic with task input from punched tape;
- automatic with task input from punched tape.
The mode is selected using switches located on the control panels of the machine and the CNC.
Setting up the machine
Regardless of the position of the operating mode switch on the CNC console, the adjustment mode is turned on by switch 23 located on the machine control panel (Fig. 4.7). In the adjustment mode, carried out by means of controls located on the machine console, the following is performed: turning the turret to a given position; pressing out the tool; turning spindle rotation on and off; moving the table along the X and Y axes in accordance with the selected speed and direction; moving the turret support along the Z axis in accordance with the task.
Setting the working parts of the machine to the zero position
The working parts of the machine are set to the zero position automatically before the “Program Entry” command. When button 15 is pressed, the turret support quickly rises until the limit switch is activated along the Z coordinate. The table moves until the limit switches are activated along the X and Y coordinates, and at the same time commands are sent to the CNC about the initial position of the working parts. The installation cycle is complete.
Rotating the turret
To select the position of the turret head, switch 24 is set to the desired position. By pressing button 6, the cycle of turning the turret head to the position specified by switch 24 begins. When you press button 6 and there is no task, the head moves non-stop.
Turning on the spindle in the “Setup” mode
The spindle is turned on in the “Adjustment” mode for all operations (except for thread cutting) with button 21, and turned off with button 22 (when threading, buttons 21 and 22 do not work). The spindle rotation speed is set by switch 27.
Movement of working bodies along the X, Y, Z axes
Movement of working bodies along the X, Y, Z axes. The selection of the working axis is made by switch 4.
The selection of fast, medium or slow movement is made by switch 7, and the selection of the direction of movement is made by switch 5.
Setting the program start in the XY plane
To adjust the start of the program in the XY plane, catchers or center finders are used. In manual mode, the spindle axis is aligned with the beginning of the program, and the zero offset values along the X and Y axes are entered on the CNC control panel, which give zero readings on the digital display.
The machine is adjusted along the Z axis after installing the cutting tool in the turret spindle. In the initial position of the caliper, check that the turret head does not touch the device with the workpiece clamped in it when rotating.
