The purpose of the invention is to improve the machining accuracy 11 (2 o W ki by increasing the rigidity of the machine. The machine for cutting workpieces contains a frame 5, carrying a horizontal table 1 with a longitudinal 2, transverse 3 and vertical 4 calipers and spindle headstock 6, and the axial supports 8 with bushes 13 carrying the removable spindle 15, and on the center supports 8, end depressions 11, designed to mate with the end projections 12, are aligned on sleeves 13 installed on both sides of the removable spindle 15 and connected to the latter by means of hollows made on its surface, and protrusions 14 on the inner surface of the sleeves, while the sleeves are spring-loaded in the direction of the spindle heads 6. 1 s. with GcheE SO with 4 X)

Description

The invention relates to the cutting of non-metallic materials, mainly parts made of quartz and other hard and superhard materials with a set of diamond tools, and can be used in conditions of individual, mass and mass production in the electronic and radio engineering industry.

The purpose of the invention is to improve the machining accuracy by increasing the rigidity of the machine.

The drawing shows a machine for cutting blanks, a general view.

The proposed machine contains a horizontal table 1 with 2 longitudinal and transverse 3 calipers, as well as a vertical caliper 4, mounted on the frame 5, on which spindle heads 6 are fixed, one of which is equipped with a reciprocating carriage 7. On the spindle heads b, fixed supports 8 with actuators 9. Drives 9 are installed coaxially in spindle heads 6, and the drives are rotated in opposite directions along arrows A and B. Center supports 8 have vents 10 with dimples 11 made on them, matching existing: with the projections 12 of the sleeves 13. With their internal projections 14, the sleeves 13 mate with the depressions of the removable spindle 15, on which

Machine for cutting blanks of quartz and other hard materials, containing a frame, carrying a horizontal table with longitudinal, transverse and vertical calipers and headstock, one of the heads installed with the possibility of axial movement, characterized in that to increase the rigidity of the machine, the latter is equipped with a coaxial razor installed a specified number of stepping rings 16 and diamond wheels 17.35 placed on the spindle headshead cent-rigidly fixed support nut 18. level supports with sleeves bearing Two springs 19 are put on the spindle 15 on both sides, constantly clamping sleeves 13 In the direction of the spindle heads 6 along arrows B. The proposed machine works by removing the spindle, while on the supports there are end grooves designed to mate with the end springs protrusions made on bushings installed on both sides of the removable spindle and connected to the latter by means of cavities made on its surface, and on the inner surface of the sleeves - protrusions, while

blowing way.

On the table 1 is fixed (for example, mechanically) a quartz glass product 20 and automatically turn on

at the same time, the actuators 9, and their sleeves are spring-loaded in the direction of the shaft should be directed to the spindle heads.

opposite sides (see drawing, arrows A and B),

The product is adjusted on the table 1 by means of calipers 2 and 3, and the feed is made by caliper 4. When the specified size of the cut grooves has been reached, table 1 is retracted down from the tool so that the product 20 passes freely without hitting the diamond tool, stop the machine 20 from the table 1. Instead of the workpiece being installed, place a new one on the table 1 and the operation of the machine is repeated in the sequence described above.

Claims (1)

The deformation of the spindle, on which the bosch tool kit is installed, thanks to the proposed construction, is practically eliminated, which makes it possible to process quartz glass boats with high accuracy in the location of the grooves. Invention Formula Machine for cutting blanks of quartz and other hard materials, containing a frame, carrying a horizontal table with longitudinal, transverse and vertical calipers and headstock, one of the heads installed with the possibility of axial movement, characterized in that rigidity of the machine, the latter is equipped with coaxially disposed on the spindle heads the center supports with sleeves bearing bent on spindle heads with center supports with bushings carrying removable spindle, while on the supports there are made end depressions designed to mate with the end projections made on bushings mounted on both sides of the removable spindle and connected to the latter by means of depressions made on its surface, and on the inner surface of the bushings protrusions, while
