Inserts Developed for Boring Enable Higher Cutting Speeds
Mapal has developed the HC720, HC725, HC730 and HC735 CVD-coated inserts tailored to the demands of boring in cast material such as GJL, GJV and GJS.
Mapal has developed the HC720, HC725, HC730 and HC735 CVD-coated inserts tailored to the demands of boring in cast material such as GJL, GJV and GJS. The inserts differ in the carbide substrate used in each case, but all four provide a heat-resistant aluminum-oxide coating with good coating adhesion. According to Mapal, the cutting edges with the new coating offer the potential for an increase in the cutting speed during boring, even with dry machining. Cutting speeds of 300 m/min. are possible with these materials, offering a potential boost in productivity. At the same time, the cutting edges achieve significantly longer tool lives compared previous PVD cutting materials such as HP455, the company says.
