Work Material [Titanium Alloy]
Key Point on Machining
Chipping and fracturing is a concern during high speed roughing of titanium alloy because of
the variations in cutting resistance during the process. The new MP9130 grade with excellent
wear resistance due to multi-layering of the coating; in combination with the JL breaker with
low cutting resistance, enables a more stable high speed roughing process.
Application Example
Achieved 1.5 times longer tool life with reduced chipping of the insert.
