Description

I

The invention relates to metal working.

The purpose of the invention is to increase the cutter's drainage by increasing the cooling efficiency of the cutting element by inserting a container attached to the holder and communicating with the front surface and side edges of the cutting element, and making a channel in the holder for connecting the cavity on the bearing surface to the container.

FIG. 1 shows the proposed cutter, top view; in fig. 2 is a section A-A in FIG. one.

The cutter contains a holder 1 with a head 2 on which it is fixed, for example by soldering or mechanical fastening with the help of a pin 4, a wedge 5 and a screw 6, a cutting element 3, connected to the cavity 7 in one side of the cutter, which is connected to the cooling agent inlet 8 . The cavity 7 is connected by a channel 9 with a container 10 fixed on the head 2, so that the cutting element 3 has a front surface and lateral edges connected to the container 10. The front part 11 of the container 10 can

be equipped with a carbide plate. I

A cooling agent, such as a liquid, from the machine cooling system is fed through channel 8 to the cutting element 3 and the heated zone located below the cutting tip. Then the cooling agent sequentially bypasses the cavity 7, picks up heat from the inside of the cutting element 3, picks up heat from the inside of the cutting element 3, and through channel 9 enters it) 5 bone 10, covering element 3, picks up heat from its back, side and upper sides. Further, flowing out of the container 10, the cooling agent fills the space above the cutting element 3, going out towards the main cutting and auxiliary rear surfaces, completing the heat removal from the cutting element 3. The front part 11 of the container

25 10 can be equipped with a carbide plate and used as a chip breaker element that is intensively cooled with a coolant, not heating the cutting element 3.
