Column
Cross table

On the base (bed) 1 of the machine, there is a slide 2 of a cross table, which has a telescopic protection of the guides. The spindle head moves along the vertical guides of the column, on which a six-spindle turret is mounted, which allows automatic tool change according to the control program. To speed up manual tool change, a special punch-out device is provided in the turret. The machine can be controlled from the pendant.

Machine movements

The main movement is the rotation of the spindle with the tool
Moving along the machine axes:

X-axis - longitudinal feed - longitudinal movement of the table along the guide slide
Y-axis - cross feed - cross movement of the slide along the bed guides
Z-axis - vertical feed - vertical movement of the spindle head (support) along the rack guides

Auxiliary movements - rapid movement of the slide, periodic rotation of the turret, precise and accelerated movements of the table and slide (positioning movement).

To control the table movements (coordinates X and Y) from the program recorded on punched tape, the machines are equipped with various CNC devices (one of the most common is CNC "Coordinate S-70"). Z-axis feed is carried out in cycle control mode. For coordinate movements of the table, manual data entry on the CNC control can also be used. The presence of a digital indication allows you to visually observe the position of the table, as well as control 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 punched tape. Circular electrocontact code converters are used as feedback sensors. The movements of the turret at rapid and working strokes in both directions are limited by adjustable cams acting on switches (electric stops).

Kinematic diagram of the drilling machine 2R135F2-1

Kinematic diagram of the drilling machine 2r135f2-1 with CNC 2P32-3

The kinematic diagram of the machine (Fig. 4.6) consists of the following independent kinematic chains: drive of the main movement (rotation of the turret spindles); cross table feed drive; turret caliper drive; turning the turret; extrusion of the tool from the spindles.

Main movement chain

Chain of the main movement: two-speed asynchronous electric motor M1 (N = 4 / 4.5 kW; n = 1470/990 rpm) - gear train 29/41-shaft I - shaft II (through gears 24/48 and 36/36 at M1 and M2 clutches on or through gear 14/36 with clutch M3 on) -shaft III (via gears 14/36 and 48/24 with clutches M4 and M5 on) -shaft V through bevel gear 21/21 - to one of the turret spindles through 35/42 gears; 31/49; 49/47; 47/35.

Cross table feed drive chain

The drive chain of the cross table feed has two gearboxes, one of which moves the table along the slide (X axis), and the second moves the slide along the bed (Y axis).

Kinematic chain of the drive of the carriage

The kinematic chain of the drive of the carriage provides them with fast, medium and slow movements. Rapid movement (at a speed of 7000 mm / min): electric motor M4 (N = 0.6 kW; n = 1380 rpm) - gears 16/40; 34/22; 22/52; 52/34 - ball screw.

Moving at an average speed (200 mm / min): M4 electric motor - gears 16/64; 25/55; 25/55; 38/42; 22/52; 52/34 - ball screw. Slow movement (at a speed of 50 mm / min): M4 electric motor - gears 16/64; 25/55; 25/55; 16/64; 22/52; 52/34 - ball screw. A feedback sensor is mounted on the ball screw.

Moving the table along the slide comes 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 for the movement of the slide.

Turret caliper drive chain

Caliper drive chain with a turret: electric motor M2 DC (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 DZ feedback sensor.

Turret Swing Drive Chain

Turret turning drive chain: M3 electric motor (N = 0.7 / 0.9 kW; n = 1400..2700 rpm) - gear 23/57 - worm gear 1/28 - gear 16/58 - turret body ...

Pressing tools out of the spindles

Pressing tools out of the spindles: M3 electric motor - gear 18/52 (with the clutch engaged) - worm gear 1/28 - gear 21/21 - eccentric mounted in the groove of the turret pivot axis and the pressing tool.

Turret Caliper Lubrication

Lubrication of the turret caliper is carried out forcibly according to the following scheme: electric motor МЗ - gears 18/52; 52/75 - eccentric EZ, which drives the plunger pump.

Gearbox lubrication

Lubrication of the gearbox is carried out from a gear pump driven by an electric motor of the gearbox through a 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 it is drained into the reservoir. The oil level is controlled by an oil indicator.

Lubrication of the slide feed gearboxes and the cross table

Lubrication of the feed reduction gears of the support and cross table is carried out by splashing oil with gears. The oil level is monitored visually using oil indicators.

Lubrication of the guides and screw pairs of the cross table

Lubrication of the guides and screw pairs of the cross table is carried out manually using a lubricator. The bearings of the turret spindles are lubricated with a 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 directing 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 supply) and stops when the caliper begins to return to its original position (in this case, the corresponding toggle switch on the control panel must be turned on).

Electrical equipment of the machine

The electrical equipment of the machine consists of a freestanding cabinet of relay automation and CNC control, as well as of elements installed directly on the machine. Electrical connections between the nodes of the machine tool and the CNC Unit are made with bundles in metal hoses ending in connectors.

The electrical circuit of the machine provides the following modes of its operation:

adjustment;
semi-automatic with the input of the task from the switches of the CNC Unit;
semi-automatic with input of a task from punched tape;
automatic with the input of a task from a 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 control panel, the setting mode is switched 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 control panel of the machine, the following is performed: turning the turret to a predetermined position; pressing out the tool; turning the spindle on and off; moving the table along the X and Y axes in accordance with the selected speed and direction; movement of the turret support along the Z-axis in accordance with the task.

Installation of the working bodies of the machine in zero position

The installation of the working bodies of the machine in the zero position is carried out in automatic mode before the command "Enter the program". When button 15 is pressed, the turret support quickly rises until the limit switch is triggered in the Z coordinate. The table moves until the limit switches in the X and Y coordinates are triggered, while commands are sent to the CNC Unit about the initial position of the working bodies. The installation cycle is over.

Turret rotation

To select the position of the turret, switch 24 is set to the desired position. By pressing the button 6, the cycle of rotation of the turret head to the position set by the switch 24 is started. When you press button 6 and there is no task, the head makes a non-stop movement.

Switching on the spindle in the "Set-up" mode

Switching on the spindle in the "Adjustment" mode for all operations (except for threading) is performed with the button 21, and switching off - with the button 22 (during threading, buttons 21 and 22 do not work). The frequency of rotation of the spindles is set by switch 27.

Moving the working bodies along the X, Y, Z axes

Moving the working bodies along the X, Y, Z axes. The choice of the working axis is made with switch 4.

The choice of fast, medium or slow movement is made with switch 7, and the choice of the direction of movement is made with switch 5.

Setting the program start in the XY plane

To adjust the start of the program in the XY plane, catcher mandrels or center detectors are used. In manual mode, the spindle axis is aligned with the beginning of the program, and on the CNC control panel, such zero offset values along the X and Y axes are set, which give zero readings of the digital display.

The adjustment of the machine along the Z axis is performed after the installation of the cutting tool in the turret spindle. In the initial position of the support, it is checked that the revolving head does not touch the device with the workpiece clamped in it during rotation.

The CNC vertical drilling machine, which is in demand at many enterprises, is divided into different types and classes of complexity. Such machines are used to perform work on drilling various holes in workpieces; engage in countersinking, reaming.

For these operations, as well as for threading inside the part, they use drills with cylindrical or conical shanks, threading heads, reamers, countersinks, taps, and other tools.

Advantages

The main parameter of drilling equipment is ideally accurate holes. The achievement of this goal is served by the capabilities of such drilling machines:

desktop and column;
those in which the spindle is fed automatically;
vertical - with one or several spindles;
aggregate and specialized;
horizontal-center, radial and thread-cutting.

Taking into account the peculiarities of the products, production volumes, it is good to have stationary equipment of all types in the technical base of the enterprise in order to perform drilling on the machines that are optimal in this case.

Applications of the equipment

The main field of application of drilling machines is metalworking operations. Clamping of tools in the spindles is vertical, and the workpieces to be processed are fixed on the work table. It is very difficult to move parts by eye to align the axis of its future hole with the axis of the drill. Therefore, this process is automated in order to orient the workpiece, to obtain a hole with the desired diameter.

The programmed equipment catalog includes the following items of demanded machines:

desktop - with one spindle, used for drilling small holes - up to 12 mm;
radial drilling - with its own scope of application, processing large heavy workpieces and drilling holes that need to be placed in an arc;
horizontal drilling - for making deep holes in units for small arms, artillery weapons;
central - with its participation, center holes are drilled at the ends of the blanks;
multi-spindle - effective if you need to drill several holes at the same time;
with a swivel spindle - capable of working simultaneously in two planes;
aggregate - has several power heads that act independently;
the special machine is limited to a set of certain functions.

Equipment has been created that performs combined processing of workpieces: with drilling and boring functions at the same time, for drilling and cutting operations (multi-spindle version) and automatic centers for drilling a profile.

When it comes to working with wood, vertical, working from one or two sides are popular; performing drilling together with milling and slotting works, they are also intended for the manufacture of grooves, nests and removal of knots.

Vertical type machines

A distinctive feature of such machines is that the arrangement of the cutting tool on the stand is vertical, it starts moving thanks to a powerful electric motor. And the movable beam moving along the rack is a place for the location of the main units that ensure the technological process.

The control type for most vertical machines is manual or semi-automatic.

But when efficient work is needed to establish mass production, a vertical CNC drilling machine is preferred. It can be radial (normal or high-speed); with box-section column, cantilever or magnetic cushion.

Serial production longevity

Among the machines for drilling vertical type, there is a model 2r135f2. Its serial production began back in 1979. This domestic unit, along with other popular models, is produced at the Sterlitamak Machine-Tool Plant. In addition to drilling metalworking equipment, the company produces a variety of honing machines - grinding and lapping, used for rollers, plungers, bushings, concentric holes in parts. Dozens of models of metalworking equipment and cutting tools roll off the factory conveyor.

If we talk specifically about the 2p135f2 model, then it belongs to the especially functional ones. This vertical CNC drilling machine in the turret has six spindles, a coordinate table, also called a cross. It is he who contributes to maximum rigidity, high accuracy, provides convenient installation and tool change.

It carries out work on:

countersinking, drilling, reaming and reaming;
milling workpieces in the technological process;
processing of parts, dispensing with preliminary marking;
threading;
coordinate processing of workpieces.

This type of equipment has many advantages. It is enough to name only 5 main ones:

Works with a wide range of spindle speeds and feeds.
It autonomously selects the standard processing mode for workpieces from different materials.
Accuracy of the distances between the axes of the machined holes is achieved.
In reality, turning on the automatic mode, turn the turrets.
Automatically performs multi-hole work with a large number of holes.

By design, the machine is extremely simple. Its base is connected to the column, and the support moves along the vertical guides. The column has been rigidly mounted on the feed reducer and gearbox. The slide moves on the base of the coordinate table. They move the desktop in the lateral direction. With the help of a gearbox, the table can be moved in the other direction.

The 2R135F2 model was assigned the highest quality category, and the numerical control simultaneously ensures the movement of the desktop in two axes - with precise positioning up to 0.05 mm.

Equipment of new models

Enterprises also demanded models with CNC - F6, F8, F10. They are used to drill through and blind holes in the planes and ends of furniture boards, billets from a bar with high accuracy. They then go to the manufacture of cabinet furniture.

Such equipment has found application in furniture factories engaged in mass or serial production of products. The machines have many advantages:

in one pass of the workpiece, the process of drilling all the cards of the additive is provided;
simplicity in work: there is no need to reconfigure the machine for each detail, the required program is selected and a new type of workpiece is installed;
ease of programming: the optimization program itself chooses the additive option (the fastest with a given tool);
a pass-through mode of operation is possible (the machine is serviced by two) or the mode of returning the panel to loading (when one operator is working);
reliable fixation of workpieces is ensured by pneumatic brakes;
the equipment can be controlled using an ergonomic remote control with display of all operations performed.

Machine operators have the ability to adjust the length, width and thickness of the material, and vertical spindles (there are 7 of them) and 1-2 horizontal ones are involved in the work.

Horizontal drilling centers

CNC boring machines with a horizontal arrangement are convenient to process massive workpieces in a short time, the spindle with a cutting tool - a large drill in them is located in the horizontal plane. On many models, the workpiece is stationary. The tools themselves, thanks to the presence of a rotating drum (there are several movable spindle heads on it), approach the workpieces, unmistakably finding the drilling points.

A range of modern drilling equipment, in addition to machine tools that can be found in garages, auto repair shops, furniture production, in the aircraft industry and instrument making; is represented by reliable and most accurate high power numerical control drilling centers, guaranteeing the highest quality.

Conclusion

Drilling equipment with numerical control capabilities is in demand in the field of industrial production, especially vertical type of machines. When purchasing it, many are guided by the brand or are guided by financial considerations, choosing a technique of domestic production or manufactured abroad. The main thing is that the machine has a factory warranty from the manufacturer, corresponds to its purpose and accurately performs its functions.
