Multilayer Insert Coating Enhances Steel Machining
Kyocera Corp.’s industrial cutting tool insert series features coating technology and a base material to improve steel machining.
Kyocera Corp. has developed a durable coating technology and base material for its indexable cutting tool inserts. The CA025P CVD coated carbide grade is designed for durability and resistance against wear, fracturing and chipping.
The company’s new cutting tool series features this multilayer CVD coating with a layer using a thick film of aluminum oxide for high heat resistance. Cemented carbide is used as a base material to promote fracture resistance, long-term performance and longer tool life. During the cutting process, the surface structure of the coating resists welding and chipping of the insert.
The cutting tools accommodate a range of machining applications from roughing to finishing with the availability of four chipbreaker styles: PG, GS, PQ and PP. The PG chipbreaker is for interrupted medium to roughing-type machining, providing good chip control and a tough cutting edge for stability. The GS chipbreaker, for continuous machining, offers low resistance with complex land. The PQ chipbreaker, for finishing to medium cutting, prevents chip clogging and lowers cutting resistance during high-feed machining. The PP chipbreaker, for finishing, prevents chip clogging and chip recutting at higher feed rates and small depths of cut. The tools are designed to reduce the frequency of insert replacements and to improve production yield.
One of the most common methods of tapping in use today on CNC machines is 'rigid tapping' or 'synchronous feed tapping.' A rigid tapping cycle synchronizes the machine spindle rotation and feed to match a specific thread pitch. Since the feed into the hole is synchronized, in theory a solid holder without any tension-compression can be used.
