为改善刀具刃口质量,除改进刀具材料和采用涂层技术以外,刀具还必须具有一定的刃口半径(ρ)、刃部工作面粗糙度和表层残留应力状态,因此国外近年多采用机械式刃口强化处理,以达到上述目的。最近苏联第四轴承厂研制一种新型强化设备—离心行星式机床,该机床对各种刀具刃口表面进行微量塑性变形处理,刀具经处理后耐用度可提高1～3倍。
To improve the cutting edge quality, in addition to improving the tool material and the use of coating technology, the tool must also have a certain edge radius (ρ), edge roughness and surface residual stress state, so foreign in recent years, the use of mechanical Edge enhanced processing, in order to achieve the above purpose. Recently, the Soviet Union Fourth Bearing Factory developed a new type of strengthening equipment - centrifugal planetary machine tools, the machine tool for a variety of micro-surface deformation of the cutting edge, the tool after treatment durability can be increased by 1 to 3 times.
