CVD Coated Cutting Material Series

MAPAL has now developed a CVD-Coated Cutting Material Series specially tailored to the demands of boring in all cast materials – GJL, GJV and GJS. The new cutting material series is extremely heat resistant and has a very good coating adhesion. These materials – HC720, HC725, HC730 and HC735 – differ in the carbide substrate used in each case. All four impress with their extremely heat-resistant ?-aluminium oxide coating with very good coating adhesion. Cutting edges with the new coating offer the potential for a significant increase in the cutting speed during boring, even with dry machining. Machining is easily possible with a cutting speed of 300 m/min, thus offering a considerable boost in productivity. At the same time, the cutting edges achieve significantly longer tool lives, as examples in practice show: When machining GJL25, the tool life was tripled compared with the PVD cutting material HP455 used to date. The whole standard MAPAL product range of indexable blades for ISO boring tools is available with the new cutting material series.
