Stainless steels have low thermal conductivity and work harden easily, and therefore cause problems like high temperature at cutting edges and adhesion to tools during cutting operations.
The "ACE COAT AC630M" carbide grade was developed for stainless steel turning that have lower machinability than general steels and regarded as hard-to-machine materials. “SUPER FF COAT” coating has a hard microfine titanium compound coating that exhibits excellent adhesiveness to carbide substrates, and newly developed, a specially-smoothed hard alpha-alumina coating. It provides enhanced chipping resistance, and also effectively prevents adhesion of work materials to tools.
ACE COAT AC630M is applicable to not only stainless steels but also general steels, and since the first time it was released, it has been satisfying customer demands for longer tool life and higher machining efficiency that leads to lower machining costs.
To suit a wider range of customer needs, Sumitomo Electric Hardmetal has added new items to the ACE COAT AC630M lineup, covering the operation range from rough machining to finishing. Especially many of the items added are those for finishing operations (FL, LU, LUW and UP type chip breakers, and positive inserts), and provide improved sharpness, reliability and cutting performance.
In steel turning operations, ACE COAT AC630M has following features: |
