For the best performance of the HSM cutting tools, it is essential to apply
• High-precision grinding
• Short overhang and thick core for minimum deection
• Short edge and contact length for minimum vibration risk, low
cutting forces, and deection
• Oversized and tapered shanks
• Holes for air blast or coolant
• Symmetrical tools
Modern cutting tools do not require cutting uids during machining. Coated
carbides, cermets, ceramics, CBN, and diamond perform better in a dry cut-
ting environment. HSM occurs at high temperatures of around 1000°C. Any
cutting uid that comes near the cutting zone will insta ...
