Small Taper Shank Turning Cutting Tool Hardness Heat Resistant

Small Taper Shank Turning Cutter

Tool material should have basic properties
The choice of tool material has a great influence on tool life, machining efficiency, machining quality and machining cost. Cutting tools are subject to high pressure, high temperature, friction, shock and vibration. Therefore, the tool material should have the following basic properties:
(1) Hardness and wear resistance. The hardness of the tool material must be higher than that of the workpiece material, generally above 60HRC. The higher the hardness of the tool material, the better the wear resistance.

(2) Strength and toughness. The tool material should have high strength and toughness to withstand cutting forces, shocks and vibrations, and prevent brittle fracture and chipping of the tool.

(3) Heat resistance. The tool material has better heat resistance, can withstand high cutting temperatures, and has good oxidation resistance.

(4) Process performance and economy. The tool material should have good forging performance, heat treatment performance, welding performance, grinding performance, etc., and should pursue a high cost performance.
