The invention relates to mechanical engineering, and in particular to methods for supplying a cutting fluid (grinding fluid) during grinding by the periphery of a wheel, and can be used in all engineering plants that use cooling during processing.

The purpose of the invention is to increase the cooling efficiency,

Fig. 1 is a diagram of an apparatus for implementing the method - side view of the end face of a circle; in Fig.2 - section AA in Fig.1 (enlarged).

The device comprises a slotted nozzle 1 for supplying coolant to the periphery 2 of the circle 3 and two slotted nozzles 4 and 5 located parallel to the ends 6 and 7 of the circle 3.

The device further comprises two nozzles 8 and 9, and the grinding wheel 3 contains cavities 10 and 11, respectively, at the ends 6 and 7, which are located in the non-working area of the circle 3. The bases of the cavities 12 and 13 contain flanges 14 and 15, which are made from the condition of formation intracavitary fluid bath coolant. The output channels of the additional nozzles 8 and 9 are placed in the planes of the cavities 10 and 11 perpendicular to their bases 12 and 13, and the distances between the axes of the additional coolant flows are chosen less than the height of the circle. In addition, the device contains nozzles 1 b and 17 for supplying coolant to two slotted nozzles 4, 5 and two additional nozzles 8 and 9, respectively. The machined part 18 is also shown. Water conduits supplying coolant to the nozzles, movement mechanisms, adjustments, nozzle mounting techniques similar to the prototype device, are well known and therefore not shown in the diagram.

The method is carried out as follows.

When grinding the part 18 with the periphery 2 of circle 3, coolant is supplied to the grinding zone from the nozzle 1, and from the nozzles 4 and 5 along the ends b and 7 of circle 3. two flat coolant flows are supplied that prevent the flow of coolant from the nozzle 1.

At the same time, two additional coolant flows are fed through nozzles 8 and 9 into the cavities 10 and 11, which are located at the ends 6 and 7, in the inactive zone of the circle 3, and contain beads 14 and 15 at the bases 12 and 13, which contributes to the formation of an intracavitary liquid bath, whence the coolant under the action of centrifugal forces through the pores of the abrasive wheel reaches its periphery.

 PRI me R. A coolant flow is supplied to the periphery 2 of a circle 3 with a diameter of 300 mm from a nozzle 1 at a speed of 10 m / s, and parallel to the end surfaces 6 and 7, a coolant is supplied from two nozzles 4 and 5 at a distance of 0.8 mm from

end faces. The width of the coolant flow supplied to the periphery 2 of the circle 3 corresponds to its height of 50 mm The width of the coolant flows from nozzles 4 and 5 is 60 mm, and the speed of their expiration is 15 m / s. A hydrocline is formed in the grinding zone, limited on one side by the periphery 2 of circle 3 and the workpiece 18, and on the other hand by liquid shutters in the form of coolant flows from nozzles 4 and 5. In addition,

cavities 10 and 11, located at the ends of the circle 3, additionally supply coolant through nozzles 8 and 9 at a speed of 1 m / s. Cavities are obtained by first removing part of the abrasive from the ends of the wheel. Radius

the bases of the cavities 12 and 13 is equal to 1 mm, and the distance from the bases of the cavities 12 and 13 to the periphery 2 of circle 3 is 40 mm. The diameter of the outlet openings of nozzles 8 and 9 is 5 mm. The ends 2 of the circle 3 are varnished. At

supplying coolant through nozzles 8 and 9 in cavities 10 and 1.1 inside the latter, liquid intracavitary baths are formed, which are bounded on the outside by beads 14 and 15, whence coolant under the action of centrifugal

forces. through the pores of the abrasive wheel 3 reaches its periphery 2, resulting in increased cooling efficiency,
