Abstract

The invention relates to a machine tool industry, and in particular to methods for supplying coolant (coolant) when grinding the periphery of a circle. The aim of the invention is to increase the cooling efficiency. When grinding a part with periphery 2 of circle 3, coolant is fed to the periphery of the circle in the grinding zone. At the same time, flat streams 13 and 14 are fed from nozzles 4 and 5 along the ends 6 and 7 of circle 3 at a speed greater than that which does not spread, which contributes to the creation of hydroclin in the cutting zone. 2 Il.

Description

1

The invention relates to a machine tool industry, and in particular to methods for the flow of coolant (cutting fluids) when grinding the periphery of a circle.

The aim of the invention is to increase the cooling efficiency.

FIG. 1 shows a diagram of an apparatus for carrying out the method; in fig. 2 is a section A-A in FIG. one.

An apparatus for carrying out the method comprises a slit nozzle 1 for supplying coolant to the periphery 2 of circle 2 and two additional slit nozzles 4 and 5 located perpendicular to the nozzle 1 along the ends 6 and 7 of circle 3. In addition, the device contains mechanisms of 8th movement and adjustment of nozzles 1, 1 and 5.

The method is carried out as follows.

When grinding part 11, the periphery 2 of the circle 3 to the periphery of the circle in the grinding zone serves from the nozzle 1 stream 12 coolant. At the same time, from the nozzles H and 5 along the ends 6 and 7 of the circle 3 additional flat flows 13 are supplied and which prevent flow spreading 12 and contribute to the creation of hydroclin 15 in the treatment zone due to the fact that the flow rates 13 and 1 are equal to or greater than the flow rate 12 The latter does not spread and completely falls into the grinding zone.

Example. On the periphery of the 2 circle 3 with a diameter of 300 mm serves a stream of 12 coolant at a speed of 10 m / s. An additional coolant supply is made of two nozzles A and 5, streams 13 and 14 of which are parallel to the ends 6 and 7 of the circle Zi and pass at a distance of 0.8 mm from the latter. The width of the stream 12 coolant supplied to the periphery 2 of the circle 3 corresponds to its height of 30 mm. The width of the additional threads 13 and 14 is equal to 30 mm, with each thread 13 and 14 overlapping a segment of circle 3 with a height of 10 and a segment of the workpiece 11 with a height of 20 mm. The flow rate of additional streams 13 and 14 is 15 m / s. In the grinding zone, hydroclin 1E is formed, bounded on one side by the periphery 2 of circle 3 and workpiece 11, on the other hand by liquid dampers in the form of additional flows 13 and 14 The method of supplying coolant during grinding. the periphery of the circle, according to which coolant is supplied to it and hydroclin is created in the grinding zone, characterized in that, in order to increase the cooling efficiency, two flat coolant flows are supplied parallel to the end surfaces of the circle with a speed equal to or greater than the coolant supply rate to the periphery the circle.
