An example of complex automation of milling machines. Automated milling machine Automated milling machine

The design of most models of modern console milling machines provides for the possibility of setting up various semi-automatic and automatic cycles of table movements. On machines of previous releases, automation of the cycle can only be achieved with the help of mechanical, electrical or pneumohydraulic attachments.

With complex automation, the cycle of table movements is supplemented automated cycle operation of the loading device and clamping device. These two cycles are strictly linked to each other and are automatically controlled from the stops located on the machine. The stops can act on the limit switches, the commands from which are transmitted by the electromagnets of the pneumatic valves, or on the handles of the distribution valves.

In FIG. 109 shows a diagram of a typical pneumohydraulic device designed to automate console milling machines models 680 and 610. The pneumohydraulic drive provides the following automatic cycle: fast approach of the table with the part to the cutter, working feed, fast retraction of the table to its original position. The operation of the loading device and fixture is consistent with the movements of the table; the scheme of the device allows you to change the feed rate on any part of the path.

The figure shows: I - a box with pneumatic equipment for reversing the table feed; II - a box with hydraulic equipment for regulating the table feed speed; III - pneumohydraulic cylinder; the left cavity of the cylinder is filled with compressed air, and the right - with oil.

When opening the inlet valve 1 (Fig. 109, a), the air coming from the network through the distribution valve 5 enters through the tube b into the left

cavity A of the cylinder 13 and informs this cylinder of an accelerated movement to the left along with the table 14 of the machine to which it is attached; the piston 12 is fixed on the machine motionless. From the right cavity B of the cylinder, the oil is freely displaced through the pipe d through the open valve 8 into the oil tank 11 (the first phase of the cycle).

With further movement of the table, the cam 15 fixed in its side groove through the lever 7 with the roller closes the valve S, after which the oil displaced from the right cavity passes through the pressure reducing valve 9 and the throttle 10 \ from this moment a slow working feed is performed (the second phase of the cycle) . The purpose of the pressure reducing valve 9 is to ensure a constant pressure in front of the throttle to stabilize the feed rate when the resistance forces change during processing.

Automatic switching of the distribution spool 5 and reversal of the table are carried out by stops 16 and 17 through the auxiliary spool 3 (servo spool). At the end of the working feed, stop U7, acting on the handle of the servo spool, switches the main spool 5 and compressed air from the network begins to flow through the tube into tank 11.

Compressed air, putting pressure on the oil, displaces it from the tank 11, and it, bypassing the mechanisms 9 and 10, through the check valve 6 freely enters the right cavity B of the cylinder and causes an accelerated reverse motion of the table; at this time, the air from the left cavity A of the cylinder through the spool 5 and the muffler goes into the atmosphere (the third phase of the cycle).

The need to use a servo spool 3 with a double-sided piston 2 is caused by the following. During the transition from the second phase of the cycle to the third, the spool is switched by a slowly moving machine table. As a result, there is a “dead” position of the mechanism, in which the channels for the intake and exhaust of air are blocked and the supply of the table is sharply reduced or completely stopped. The use of a servo spool ensures instant switching of the main distribution spool 5.

With the "dead" position of the servo spool 3 shown in Fig. 109, b, air from the network continues to flow freely into the spool 5 (Fig. 109, a) through channel a and further along. tube b-cylinder. Therefore, the working feed of the table does not stop. When the spool 3 passes the vertical position, the air from the network will instantly move the piston 2 to the right and thereby also instantly turn the spool 5 connected by the gear 4 to the piston 2. In this case, the air from the cylinder 13 is released into the atmosphere, and the air from the network enters the tank 11 and table 14 starts to move quickly to the right. Then the stop 16 again switches the spools and the first phase of the cycle is repeated, etc.

A section of the pneumohydraulic cylinder 13 with a fixed piston 12 and a hollow rod is shown in Fig. 110. The cylinder is attached to the table, and the piston is attached to the cross slide of the machine. According to the layout conditions of the pneumohydraulic device, the cross slide of the machine was replaced with new ones.

The design of the box with pneumatic equipment is shown in Fig. 111. The main elements of the box are: flat distribution

spool 5, flat servo spool 3 and double-sided piston 2, the rod of which is made in the form of a rail.

The servo spool is controlled by cams 16 and 17 installed in the side groove of the machine's desktop. Handle 18 is designed to control the spool during adjustment.

With the positions of the spools shown in Fig. 111, air from the network through channel A and through a through hole B in spool 5 enters cavity C, pressing both spools against the plane of the box body. From cavity B through the through hole D in the spool 5 and channel D, air enters the left cavity of the working cylinder and causes the table to move to the left.

From cavity B, air also enters through the through hole Y in spool 3 and channel K into the right cavity L of the auxiliary cylinder. In this case, the left cavity M of the cylinder through the channels I and O, the groove I in the auxiliary spool and the channel P is connected to the atmosphere.

When the table comes to the extreme left position, the cam 17 turns the auxiliary spool 3; in this case, the through hole C in the spool coincides with the hole O, and the groove I connects the channels P and I. Then the air from the cavity B through the channels O and I goes to the left cavity M, moves the piston 2 to the right and through the gear 4 turns the distribution valve 5. In this case, hole B is connected to hole 7 a, groove G communicates hole D with channel F. Air from cavity C enters through channel E into the oil tank, displaces oil from there, which passes into the right cavity of the working cylinder, and the table begins to move to the right. The left cavity of the working cylinder is connected to the atmosphere. In the body, in addition to the spools, an inlet valve 1 is mounted.

Box II with hydraulic equipment is shown in Fig. 112. Its purpose is to change and stabilize the speed of the table. It consists of a throttle 10 with a handle 19, a plunger S, a pressure reducing valve 9, a check valve with a spring-loaded ball 6 and a sleeve 22, and a pipeline 21.

With an accelerated idling of the table to the left, the oil displaced from the hydraulic cavity of the cylinder, passing through channels L and B, presses the ball 6 to the sleeve 22. Then the oil is directed through the raised plunger 8, channels B and D, cavity O and through pipeline 21 into the tank.

At the end of the idle stroke, the cam 15 mounted on the table (see Fig. 109, a) presses the plunger 8, closing the passage of oil into channel B. Then the oil displaced from the cylinder passes through channels L, 5, C, through the cavity P of the reduction valve, throttle 10, channels E, K, G and cavity O into the tank, carrying out the working feed of the table; the length of the path at the working feed is determined by the length of the cam 15. The speed of the working feed is determined by the value of the open gap of the throttle 10, adjustable by the handle 19.

During the reverse accelerated course of the table, the oil coming from the tank lifts the ball 6 and passes through channel A directly into the hydraulic cavity of the feed cylinder.

In FIG. 113 and 114 show the design and operation of an automated fixture for milling with a set of milling cutters of two parallel flats on a turnkey basis at the same time for four bushings. The blanks are loaded into four magazines 1 (FIG. FROM) with the shoulder down; stores are fixed on the trunk of the machine with the help of bracket 2 and remain motionless during operation.

The workpieces entering the nests are mounted on a movable lower support 3 and are clamped by two pneumatic cylinders And, each of which, acting through the lever 12, the rod 13, the rocker arm 6 and the plungers 5, simultaneously fix two parts. On the body 16 of the fixture, a part 7 is fixedly mounted with two brackets 8, with which the levers 12 are pivotally connected.

Adjustment to the required size of the clamp is made by rotating the right side of the rod 13 relative to the left with the rocker arm 6 removed. In the extreme right position of the device, the movable support 3 is automatically removed, since the bar 9 fastened to it with the stop screw meets the magazine stop 14 and moves away, compressing the spring 10. This allows the processed parts to fall into the tray.

The air supply to the cylinders 11 is regulated by the distribution valve /5, which is controlled by fixed stops 4U
fixed on the machine bed.

Loading the workpiece (Fig. 114, a) corresponds to the position indicated in Fig. 113. In the presence of a throttle 17, the passage of air into the cylinder 11 is delayed and the part has time to enter the fixture socket. In FIG. 114, b the workpiece is finally clamped, and the table is switched to the working feed; in fig. 114, in the right stop 4 switches the valve /5, which connects the cylinder 11 with the atmosphere; the workpiece is released. The stop 14 of the magazine moves the movable support 5, and the processed part falls into the tray.

In the layout with the considered pneumohydraulic drive, other devices for automated processing various details.

In FIG. 115 shows a semi-automatic tool for cutting segmented keys.

Workpieces in the form of disks are loaded into the magazine tray 6 and rolled into bed 5 under the action of their own weight. drive the sled 3 with bed 5 fixed on them, pneumatic cylinder 2 and clamp 4. When the sled 3 moves, the cam 16 presses on the valve spool 17. The piston of the pneumatic cylinder 2, descending, through the lever 4 clamps the workpiece, which, with further movement of the sled 3, is fed to cutter.

At the end of the cutting, the rotating drum 14 with the cam 15 moves the sled 3 to the right, and the sled 8 with the cam 12. When the sled 3 moves away, the spool of the pneumatic valve /7 is switched, the piston 1 rises and squeezes the part. Sled 8 with cutter 7, returning back, open the outlet of tray b, and the new workpiece falls into bed 5. During the secondary cycle, the new workpiece, moving along the groove of bed 5, pushes the cut workpiece out of there.

The copy drum 14 receives rotation from the lead screw of the machine table through gears 9 and 10. To prevent the table from moving when the lead screw rotates, the lead nut is dismantled.

In FIG. 116, a shows an automated fixture for a milling machine.

On the plate 1 of the fixture, a body of 8 pneumatic vices is fixed. When the rod 2 of the pneumatic cylinder moves from right to left, the force through the bar 17, the lever 15 and the stop 20 is transmitted to the slider 7. The prism 5, fixed in the slider 7, clamps the part, pressing it against the fixed prism 4.

Simultaneously with the clamping, the rod 2, through the system of levers 9, 10 and the sleeve 12, brings the ramming plunger 11 out of the guide sleeve 13, and the new workpiece from the cassette 3 enters the loading position.

The unclamping is performed when the rod 2 of the pneumatic cylinder moves from left to right. Plunger 7 with prism 5, under the action of spring 6, releases the machined part, which falls between prisms 4 and 5. Following this, rod 2, through levers 9 and 10, plunger 11 sends a new workpiece into the processing zone until it stops 21. Rod 2 at the end of the stroke unfolds the lever 18 with adjustable heel 19 and returns the plunger 7 with the prism 5 to such a position that the sent workpiece does not fall after the finished part.

In FIG. 116b shows the device operation control scheme.

Before starting work, the pneumatic valve 26 is turned on, and air enters the cylinder and the travel pneumatic switches 14 and 16. Then the spindle rotation and table feed are turned on. After the part leaves the processing zone, the pneumatic switch 14 finds on the stop 25 and through the remote pneumatic switch 22 gives the command to open. At the same time, the table approaches the limit switch (not shown in the figure). The feed is reversed. The table starts to move to the left. The pneumatic switch 16 fits under the stop 24 and gives the command to clamp. After milling, the pneumatic switch 16, sliding along the stop 24, leaves it and prepares the fixture for unclamping.

The stops 24, 25 are fixed on the machine frame in the guide 23.

Technological progress does not stand still - today, most of the operations for which people were previously responsible are assigned to computerized control systems. One of the clearest examples is milling machine with CNC. Numeric program control facilitates the operation process, improves the quality of the output products and optimizes the production process.

Programmable milling cutter: features of work

A CNC machine with a milling cutter can perform a large amount of work: drilling, cutting, calculating the distance for holes, and others. As a raw material, as a rule, wood, polymers, metals, stone are used. The milling unit has the main working part - a milling cutter, which makes the drilling or cutting process possible. These devices are most relevant for furniture production, as well as companies engaged in the production of souvenirs and other similar products.

The use of such machines allows you to increase productivity, the accuracy of manufacturing products, reduces the involvement of personnel in the work process, and the time required to prepare products is significantly reduced.

What should be considered when choosing?

If you need to buy a milling machine, pay attention to such points:

• workpiece dimensions (determine the most dimensional headings that you have to process, this will avoid the need to reprogram the equipment);
• design features(it is better if the surface of the portal is made of resistant and solid cast iron, and not aluminum);
• type of motor (servo motors are more acceptable options because they provide higher quality products);
• tools (before choosing and buying, be aware of how many tools will be used in the work - if there are a lot of them, then choose models with a module that automatically changes tools and saves operators time);
• software(ask what software is installed on the equipment, and if you have problems with English language, specify information about Russian localization).

Varieties of CNC milling machines

Modern milling machines for wood, metal, stone can be conditionally divided into two main types: cantilever and non-cantilever. Among the console varieties are: universal, horizontal and vertical machines. It is the console options that are the most popular and in demand. Consoleless options work according to this principle: both the working surface and the working tool can move in them in two directions.

In the Top3DShop online store you can buy a CNC milling machine inexpensively. The range includes home, coordinate milling, drilling and milling, 3D units. You can equip your production with quality machines - cheaply and with minimal cost time. We guarantee prompt processing of orders and delivery within Russia. These are modern machines that will improve the quality and speed of work in your production.

Milling in 3D in the production of decorative and interior elements, advertising products, souvenirs. They cut curvilinear details of furniture and facades made of natural wood, perform relief work (engraving). In addition to wood, acrylic, plywood, MDF, gypsum, soft metal alloys can be processed.

The process of processing the material takes place under the control of electronics according to a pre-prepared program. Such production is characterized by speed and high accuracy of work.

Classification of CNC routers

CNC milling equipment differs in technological capabilities: processing speed and workpiece size.

Household CNC routers perform engraving rather slowly and are equipped with weak electric motors. However, they are small and lightweight. Designed specifically for wood processing in home workshops. The machine is placed on a table or workbench and is designed to perform small parts. It can be operated by a novice master as study guide or for the manufacture of small single orders.

Industrial milling machines with numerical control are designed for long work under the control of automation. They are equipped with powerful electric motors, durable mechanical components and a necessarily increased cutting surface. The equipment is used for production processes that require high processing speed and maximum accuracy, for example, when cutting large sheets of MDF, chipboard.

Industrial milling lines operate in a fully automatic mode. The machine independently replaces workpieces and cutters, processes parts from five sides. Automatic change of cutters is carried out by the Automatic Tool Change System, which can be in-line or carousel. The lines are equipped with the highest quality mechanisms and complex programs.

Depending on the location of the cutter, machines can be:

• vertical milling;
• horizontal milling.

In industry, vertical milling machines are more widely used, which carry out processing more accurately and provide rigid fixation of the workpiece. Such a milling cutter can also process parts at an angle, regardless of their dimensions.

The machines differ in the number of spindles: 2-spindle, 3-spindle and 4-spindle models. With an increase in the number of spindles, productivity increases.

The device and equipment of CNC milling machines

The principle of operation of CNC milling machines is based on a positioning system along the coordinates of three axes: X, Y, Z. All movements of the carriage with the cutter are performed under the direction of the CNC along the axes. As a rule, the system is implemented in the following way:

• Y-axis - along the plane of the desktop;
• X-axis - across the plane of the desktop;
• Z-axis - in the vertical plane.

The positioning system for each axis consists of:

• electric motor;
• drive systems;
• guiding devices.

The positioning accuracy and the quality of the final product depend on the properties of the supports and guides. The guides must be made of high-alloy steel and can be with a rectangular or round section.

Guides are installed as follows:

• along the X-axis for the movement of the portal from the two ends of the table;
• along the Y-axis on the portal for moving the carriage with the cutter;
• along the Z-axis on the carriage to move the cutter itself.

In addition to the listed details, the design contains:

• support device;
• shaft mechanism;
• Desktop;
• bed;
• kit cutting tools(knives, cutters);
• clamps for fastening parts.

The cutters are attached to the shaft using a cone or collet chuck that comes with the kit.

The electric motor transmits the movement to the calipers, beams (portals) and spindles by means of a gear or screw transmission. The spindle is equipped with air or water cooling.

To carry out rectilinear milling, a linear guide device equipped with clamping mechanisms is additionally used.

Motor type

Electric motors are installed on CNC wood routers:

• step type;
• with feedback (servomotors).

The type of electric motor depends on the planned tasks and the power of the machine.

A stepper motor transforms electrical impulses into mechanical movement of the rotor with a stop in the desired position. This type of motor provides precise speed control and positioning without the need for a controller. feedback. It is very easy to maintain and relatively inexpensive. At the same time, the engine speed does not exceed 1000 rpm, and at maximum loads there is a possibility of step loss.

Servo motors, unlike stepper motors, do not spin constantly, but upon receiving a signal, they move and stop until the next signal. Servo drives have a feedback mechanism that allows you to correct errors. This means that if you press on the drive, it will resist, trying to return to the desired point.

Servo motors rotate faster, they are more powerful and more accurate. But significantly increase the cost of the router. Their maintenance requires special skills, therefore it is trusted to qualified personnel. Servo motors are also more difficult to control.

A servo-driven milling cutter is required for high-speed processing of materials (often cutting sheets) or for the manufacture of high-precision dies.

Accessories

By special order, the CNC router is equipped with additional devices that expand the functionality:

• fourth rotary axis: allows you to make parts of a spherical, conical or cylindrical shape, decorated with carvings. For example, columns, posts, balusters, furniture legs of complex shape;

• vacuum tabletop: necessary for frequent cutting of sheets of chipboard, MDF, plywood into elements of complex shape. The vacuum pump table holds the cut pieces tightly without the use of mechanics.

Choice of CNC Router

When choosing CNC milling equipment for wood, you should take into account the most important characteristics.

Worktop dimensions

They determine the size of the workpiece that can be milled on this CNC machine. The size of the tabletop should be slightly larger than the planned dimensions of the workpieces, so you first need to decide on the scope of the machine:

• if it is planned to carry out an overhead thread, 90 x 60 cm is enough;
• for panels, paintings and furniture facades - 120 x 120 cm;
• for milling door panels - 130 x 250 cm;
• for the manufacture of small items, souvenirs - from 30 x 30 cm.

Spindle type and power

To work with small elements, a spindle power of 1500 to 2200 watts is sufficient. If you plan to cut material deeper than 80 mm, cut thick plywood, wood, MDF - you need a spindle with a power of 3000 W or more. For processing parts made of fluoroplastic, a low-power 1500 W is suitable. Industrial CNC machines with automatic cutter change are equipped with spindles with a power of 4000 W or more.

The second difference between the spindles is the cooling system, it can be water or air. When processing wood, a cheaper and simpler water cooling system is sufficient.

Height of the milled part

The thickness or height of the part depends on the Z coordinate. The maximum value of the coordinate corresponds to the distance from the portal to the tabletop and is selected as follows:.

• to work with large wood products (poles, brackets), equipment with a height of 20 cm or more is required;
• for cutting, fulfilling advertising orders and small items 15 cm is enough.

Control type

There are three options: a separate rack or console, a computer and a board, a computer and an LPT. The latter is not suitable for professional work.

The second option is convenient in that the entire progress of work is displayed on the computer monitor. It requires the purchase of a computer that is used for the entire technological process.

The console-rack is good because the control system is fully integrated with the router. For example, when there is a power outage, the machine will fix the position and start from that point. The remote control is easy to operate, protected from dust. The control program is written on a computer.

Controlling woodworking machines with a tool changer, rotary axes or multiple spindles is more efficient and easier with the help of a stand.

In addition, to increase the rigidity of the structure of the milling head and to provide the possibility of turning the drum when it is removed from the processing zone, it is mounted on a movable slide.

For planting the drum on the clamps, clamping it when processing the workpiece and pressing it to the 2p guides when retracting until the tool exits the workpiece, it is equipped with hydraulic cylinders. Hydrocyl?! Ndra move the baraba.i along the axis. In order to increase the reliability of the machine in automatic mode of operation and to ensure the convenience of controlling the working bodies of the machine during setup, it is equipped with hydraulic system control, which provides hydromechanical control from the cams in automatic pe "cute 3! 1 work and electric. drive" slant control: ne in the commissioning mode: 1 ms of work with perkgiochiiism from one mode and another using a valve with 3lec1rocontrollsh!

Before the retraction of the drum sled begins, the pressure in the part of the drum clamping cylinders is turned off, as a result of which the pressure of the latter against the frame guides is weakened, and the movement of the sled becomes possible.

After the product is removed from the cutter, the drum moves in the direction of the axis of rotation by a full amount, which ensures its release from the clamps. After the drum approaches the crimpss, it turns to the right position by 90 ", the sled with the drum is retracted to the right" so that when the device with the products is turned, it does not hit the rising milling head. not reaching the extreme left position, the drum is landed on rigid clamps.
