Avoiding burns when sharpening HSS tools

摘要

In sharpening tools of high-speed steel, inappropriate choice of technology parameters can causeburns to occur on the surface due to poor heat conductivity Discoloration of the surface can beaccompanied by cracking that reduces wear resistance, tool life and hardness. In extreme cases,cost-intensive tools can be destroyed. The choice of correct parameters is thus of utmostimportance.
