CUTTING PLATE AND MILLING CUTTER WITH COOLING Russian patent published in 2021 - IPC B23C5/00 

FIELD: processing of materials.

SUBSTANCE: group of inventions relates to processing of materials by cutting and can be used in processing of products made of hard-processing materials. The cutting plate comprises at least one main cutting edge, at least one support surface located opposite the front surface. The mounting hole comprises a section with clamping parts in the form of a second-degree surface. The surfaces of the clamping parts of the mounting hole are alternating consecutively in a circle with the cooling grooves extending along the hole from the support surface and along the front surface with an expansion to each main cutting edge. The milling cutter comprises a body in the form of a body of rotation, made on the periphery whereof are sockets for placing and securing the cutting plates with screws. The sockets have side surfaces and a support surface, located wherein is a threaded hole for the mounting screw. A central hole for the lubricating and cooling fluid is located in the body along the axis of rotation, and holes with a smaller diameter extend therefrom to the sockets in the radial direction.

EFFECT: design features of execution of the cutting plate and milling cutter provide an increase in the durability of the cutting plates and milling cutters due to the effective cooling of the cutting plates and the cutting area.
