Abstract
The invention belongs to the technical field of sharpening tools, and discloses a tool for turning superhard materials and a sharpening method thereof. The sharpening method includes: (1) using a grinding wheel to grind the main back surface, controlling the main deflection angle to 75° to 95°, and controlling the main relief angle to 15° to 20°; (2) using a grinding wheel to grind At the back of the auxiliary, control the auxiliary deflection angle to 10°-20°, and control the auxiliary relief angle to 15°-20°; (3) use the grinding wheel to grind the front, control the rake angle to 20°-30°, and adjust the blade inclination angle to The control is 10°~15°. The turning superhard material cutting tool and its sharpening method of the present invention can reduce tool wear, increase the service life of the tool, control the direction of chip removal and reduce the generation of built-up edge, thereby improving the surface quality of turning products and ensuring the turning of superhard materials The processing technology is stable, and at the same time, the turning processing efficiency of superhard materials is improved, and the production cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of sharpening tools, in particular to a tool for turning superhard materials and a sharpening method thereof. Background technique [0002] In the turning processing of superhard materials such as tungsten, due to the high hardness, high brittleness and large grain size of tungsten, it is easy to generate chip accumulation during the cutting process, and the peeling off of the chip accumulation leads to unstable processing technology and rough processing surface. The wear of the tool is reduced, and the time for regrinding the tool and resetting the tool is prolonged, which in turn leads to a decrease in processing efficiency. [0003] Figure 1a , Figure 1b and Figure 1c A conventional sharpening tool in the prior art is shown, where Figure 1a It is a schematic diagram of the structure of a conventional sharpening tool, Figure 1b It is a schematic diagram of the reference surface used to measure the ...
