Kyocera Industrial Ceramics introduces a small, double-sided negative insert tool system for Swiss-type precision machining. The double-sided insert design provides two cutting edges that are said to improve stability.
The company says that the tool’s sharp cutting edge is the equivalent of a positive insert edge, and its small toolholder design facilitates multiple tool-post locations without subspindle interference.
The inserts are available in two PVD-coated grades, PR1005 and PR1025. According to the company, PR1005 offers excellent wear-resistance for titanium and free-cutting steel, and PR1025 offers fracture toughness for stainless steel and general use.
Editor PickCan Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
