Example Embodiment

[0015] like figure 1 As shown, an indexable face milling cutter made of superhard material is provided with several installation grooves on the outer wall of the periphery of the cutter body 1, and a module 3 is fixed with a fastening screw 2 on one side of each installation groove, and a wedge is arranged on the other side. Block 4, the lower part of the wedge block 4 is connected to the cutter body 1 through the threaded column 5, a step is arranged on the module 3, and the blade 6 is placed on the step, and the two contact surfaces of the wedge block 4 and the cutter body 1 and the blade 6 are inclined planes or one of them One contact surface is an inclined plane, and the wedge block 4 presses the blade 6 tightly. The threads at both ends of the threaded post 5 are in opposite directions, so turning the threaded post 5 can make the wedge 4 move downward. Because the contact surfaces of the wedge 4 and the cutter body 1 and the blade 6 are inclined surfaces, or one of the ...

Abstract

The invention discloses a milling cutter with a rotatable face for cutting supper-hard material. A plurality of mounting grooves are arranged at the outer wall of the peripheral of cutter body, and one side of each mounting groove is fixed with a module using fastening screws, and the other side is provided with a wedge block, the bottom of which is connected with the cutter body through a threaded pillar; the module is provided with a step, and a blade is positioned at the step; two contacting surfaces of the wedge block and the cutter body and the blade are all inclined or one of the surfaces is inclined; the wedge block is closely pressed against the blade. Aimming at solving the problem that the existing milling cutter for cutting supper-hard material has unstable structure and is unable to process super-hard material with higher hardness, the invention provides the milling cutter with a rotatable face, which has a stable structure and higher processing hardness and intensity. The milling cutter of the invention has outstanding technical effect, for on one hand, installation stability of blade is improved, and on the other hand, processing hardness and intensity of the cutter are enhanced.

Description

technical field [0001] The invention relates to a milling cutter for processing superhard materials, in particular to a milling cutter for processing indexable surfaces of superhard materials. Background technique [0002] The structure of the traditional indexable face milling cutter is unstable, easy to cause displacement, and the chamfer of the insert is small, the strength is low, and it cannot withstand the processing of high-strength superhard materials; on the other hand, most of the traditional inserts are made of cemented carbide And ceramics, with the development of material technology and manufacturing technology, various high-performance new materials are emerging. Superhard tool materials have higher hardness, thermal stability, and chemical inertness than cemented carbide and ceramic blades. These new materials The cutting process puts forward higher requirements on the hardness, thermal stability, toughness and chemical inertness of milling tools. [0003] Th...
