Superhard Cutting Tools


Superhard cutting tools

Superhard cutting tools play an important role in modern machinery manufacturing. Like the automobile, railway vehicle, aircraft, machine tools, ships, such as the rapid development of manufacturing industry, new type of composite material applied continuously, and modern processing of high speed, high efficiency, high precision of processing characteristics of the cutting tool shock resistance put forward higher request, at the same time to promote the development of superhard cutting tool industry, diamond, and cubic boron nitride superhard cutting tools have been widely used. However, the impact resistance of super-hard tools is poor, especially in intermittent cutting, milling, and wide cutting edge processing, the phenomenon of edge breakage is easy to occur.

Parameters of superhard cutting tools

The reasonable determination of blade shape and geometric parameters is very important to give full play to the cutting performance of the tool. In terms of tool strength, the tip strength of various blade shapes is in order from high to low: round, 100° diamond, square, 80° diamond, triangle, 55° diamond, and 35° diamond. After the blade material is selected, the blade shape with the highest strength should be selected. Hard turning blades should also choose the largest tip radius, rough machining with circular and large tip radius blades, finishing the tip radius of about 0.8 microns. Hardened steel is red and soft ribbons, brittle, easy to break, not bonding, quench steel cutting surface quality is high, generally does not produce chip tumor, but the cutting force is larger, especially the radial cutting force than the main cutting force is larger, the tool should be used negative front Angle (go≥-5°) and a large back Angle (ao=10°~15°). The main deflection Angle depends on the rigidity of the machine tool, generally taking 45°~60° to reduce the workpiece and tool flutter.
