Description

The invention relates to the field of machining using metal-based cutting wheels and can be used in machine, instrument making and electronic industries, in particular when cutting ceramic, including semiconductor materials.

The purpose of the invention is to increase reliability.

Figure 1 shows a General view of the device at the initial moment of cutting; Fig. 2 is the same at the time the cutting is completed; in Fig.Z - device in cross section; figure 4 is a view a in figure 3; in Fig.5 is a view of B in Fig.Z; figure 6 - section bb in figure 1.

The device consists of a bracket 1 attached to the casing of the machine 2, plug 3 with hydrodynamic nozzles 4 and the role of VaMH 5. acting as a stop. The yoke 3 is connected to the bracket 1 using the axis 6 and fixed in the axial direction - on the left by the shoulder of the axis 6, and on the right - by the spring 7 and nuts 8. The spring 7 is in a prestressed state and tends to turn the yoke 3 around the axis 6 against

clockwise (Fig.6). The stopper of the fork 3 movement around the axis 6 is a screw 9, which provides a non-working gap between the roller 5 and the ingot 10 2-3 mm (the drawing shows the initial stage of the operating cycle when the roller comes into contact with the ingot).

Coolant is supplied to the nozzles through the nozzle

11k to the pipeline 12.

The device operates as follows.

Coolant through fitting 11 and piping

12 (see Fig. 7) falls into nozzles 4, after leaving which it is carried away into the gaps between the cutting wheel and nozzles, as a result of which a region of high hydrodynamic pressure is created, which dampens the axial vibrations of the circle and gives it additional rigidity.

At the beginning of the cycle, nozzles 4 are located above the cut ingot Yu (Fig. B) near the point where the cutting edge enters the ingot material. As the cutting edge deepens into the material of the ingot, the fork 3 rotates clockwise around

axis 6 (Fig. b) and nozzle 4 move to the right and allow seamless cutting to the end of the ingot. After that, the spindle assembly with the circle returns to its original position and the nozzles 4 again occupy a position above the entry point of the cutting edge of the circle into the ingot material, since the spring 7 provides constant contact between the roller 5 and the ingot 10.

Then, after the axial feed of the ingot, the cycle is repeated.
