2 / / Application Range AC610M The new carbide type with Absotech Platinum technology is recommended for high speed turning of stainless steel in continuous to light interrupted cutting. The advantage over AC610M is an improved fracture toughness and higher notch wear resistance. Cutting Speed (m/min) AC630M AC530U Continuous Light Interrupted Interrupted The first recommended grade for general machining of stainless steel drastically reduces the occurrence of abnormal damage in stainless steel machining and achieves stable long tool life thanks to the Absotech Platinum technology. The first recommended grade for general machining of stainless steel drastically improves the reliability in unstable machining thanks to the excellent adhesion and the peeling-off resistance of the new Absotech Bronze technology. The improved fracture resistance of the exclusive carbide substrate assures the production. Cutting Conditions Features The new high toughness substrate is a CVD coated grade with Absotech Platinum technology and covers a more extensive range of applications of AC610M from continuous to light interrupted cutting. The Platinum Absotech technology reduces the internal stress of coating. Due to the excellent adhesion achieves a high resistance against cutting edge chippings and enables a very stable cutting edge. There is a very good balance between wear resistance and toughness of the substrate. With the three chipbreakers NEF, NEG and NEM in combination with the grade Sumitomo offers an wide range for stainless steel machining.
