2 Features and Benefits case study BALL insert 1. Helical end gash ( "S" gash ) geometry Low milling torque Prevents chattering Improves chip ejection Prolong tool life 2. Polished cutting edges Better wear resistance and tool life Improves repeatability in performance Improves surface roughness on work-piece Improves coating CORNER RADIUS INSERT 3. Special coating Combine high hardness with high thermal stability against oxidation Superior wear resistance Faster feeds and speeds 1. The optimized tool geometry achieves better reliability and reduces vibration and cutting load.

( 20% down) Recommend to reduce the feed rate to 70~85% when you use long(long & intermediate Holder) tools. Build up edge Insufficient matching of the materials and tools or coolant oil Spray the metal cutting oil in order from dry, soluble oil to non-soluble oil During the alloyed steel cutting, active non-soluble oil type is appropriate 24 Phone: , yg1@yg1.kr Phone: , yg1@yg1.kr 25
