Abstract

A device for processing materials by cutting comprises a current source (6) of negative polarity, a unit (13) for providing air flows, a commutating unit (9) and an alternating current source (8). The device further comprises two means (2, 4) for ionization of the air flow with corresponding corona electrodes (3, 5). The means (2,4) for ionization of the air flow are connected to the unit (13) for providing air flows. The corona electrode (3) of the first means (2) is connected to the current source (6) of negative polarity. The corona electrode (5) of the second means (4) is connected to the commutating device (9). The first means (2) is directed towards the cutting zone on the side (B) of the rear surface of the cutting tool (1). The second means (4) is directed towards the chip-forming part (C) of the cutting zone. The device may further comprise a third means (19) for ionization of the air flow directed by its outlet towards the cutting zone on the side (D) of the front surface of the cutting tool (1). The electrode (20) of the means (19) is connected to the current source (21) of negative polarity. The invention makes it possible to intensify the cutting process by ensuring a greater endurance of the cutting tool (1) due to rendering the chip brittle, crushing it and weakening the layer of the material to be cut.

20 OUTDOOR STAINLESS STEAM. The first part of the unit for the creation of air inlet was connected to the inlet of the device for the initiation of air inlet. The front end of the rotary tube is communicated with the atmosphere through the rear axle. At the same time, the process of processing the materials gives rise to cutting

25 squeezed air into a vertical shaft. The flow of the starter through the first outlet is empty to the medium for the loss of air. When the inlet is supplied to the bypass, there is an external discharge inside of the initialization of the inlet air. Air Drivers

In FIG. 2, devices for machining are cut, a user-friendly execution of a manual analogue device,

25th leg in FIG. The difference is only in that the device is equipped with a third device 19 (Fig. 2) for the initiation of the power supply to the consumer, which takes into account 21 Commodity 19 is connected to the zero potential bus and

30 at the outlet 22 is connected through the valve 15 and the exhaust pipe 17 with the third outlet of the assembly of the unit 13 for the CONSTRUCTION of the air. Mediocre 19 has been established with its output in the direction of the cutting area of the front door of the external tool I. Source 21 of the output signal

357 zero potential.

Node 13 (Fig. 3) for the production of air inlets is made in the form of a source 23 of the compressed air connected to a vacuum pipe 24 for an energy separation - 8 - χа on hot and cold. When this is done, the exhaust is 16 and the hot air is exhausted, while the exhaust is 14, 17 and the factory is empty. Also, the node 13 for the creation of air flows can be performed in the form

On December 5, source 23 of the compressed air connected to the air flow separator (not shown for figures 1,2,3). In this case, the pipes 14,16,17 are free of air that has a temperature equal to the temperature of the surrounding medium.

10 This machine tool is designed for cutting and working with the following equipment.

I turn off the error (not shown in the figure) and turn on the direction of the arrow Α (Fig.) The processed part 18, executed, for example, is removed

Ιδsshivav. In doing so, it ensures the necessary services of the reliable instrument I. Before the installation of the instrument I and 18, the 15 node 13 is disconnected, it is not used. With this flow of air, emptying is

20 of 23, is divided into two flows and is divided into separate air flows for the 14 and 16 units of the medium 2.4 for the initialization of the inlet air.

For parts 18, the movable contact 10 of the commu- nity and the convenience of the device 9 connects the fixed contact

25 volume 12. For this reason, on the off-circuit elec- trode 3 of component 2 and on the off-circuit elec- trode 5 of component 4, they receive the source of source 6 of the neutral source. In result 2 and 4, a uni-versal indirect discharge arises. Air units are manufactured in a commercially available range -

Positive charges. On the other hand, in a separate order, a user is given access to it. Уль The result of these products is that the product is disposed of in a non-exhaustive manner due to the ingress of material from the vehicle.

Deliveries from the cutting area. Next, enter the cutting tool I and the processed part 18 and start the cutting process.

- 9 - At the same time, the process is secured by a high productivity of cutting, and it is the result of a loss of harm to the property.

5 lubricants and lubricants. Otherwise, the loss of food and enriched air, which is accented on the cutter, improves the aperture and

10 The option to connect the mobile terminal 10 is switched on. When this is done, on the 5th part of 4, the source is fed from the source of the 8th variable voltage. Β ρresul-

In part 4, to initialize the air flow, a variable by-pass discharge is taken. Air vents and electric shock are a different sign, and the process is more intensive in comparison with the above. Passing in the air,

20 lowering the cost of a small amount of discharges in the field, it helps to increase the profitability of the company.

After the end of the processing process, the output

The 25th tool I from the connection to part 18, turns off the source 6.8, closes the 15 knots 13, turns off the machine, removes the finished part 18 and installs the next part 18.

30 green 13 (FIG. 3) can be made in the form of a source 23 with a vertical pipe 24. In this case, it is a factory 14 factory outlet. This results in the return of a good and reduced airflow from the factory.

35the rear part of the cutter ensures additional cooling of the cutter and increases its speed. Discharge of hot and lowered air in the direction of the cut-off section from the unit provides the best conditions for - 10 - Download and add-ons for a large class of processed materials and increase the operating speed of I. Do not use them

5 The operation of the device shown in FIG. 2 is similar to the operation of the device shown in FIG. The exception is that, at the same time, the product is supplied with air and an electric power supply for devices 2 and 4, it is free of charge to the consumer.

This means that the product has been discharged for service 19. Turns off the source 21 for a faulty condition and consumes the vehicle for a loss of service. When implementing the cutting process with the transfer to the cutting area
