Kyocera Group is exhibiting a range of newly developed metalworking tools at the Japan trade show JIMTOF 2016. These will include the new CA3 Series CVD coated carbide indexable cutting tool inserts for cast iron machining; the Magic Drill DRA, a high-performance modular drill; and the MFH Micro, a tiny-caliber high-feed cutting tool, the company stated in a news release. Highlights include:
CA3 Series--New cutting tool materials for cast iron: The CA3 Series has achieved longer tool life and consistent processing of cast iron through a newly developed CVD coating with a pink-gold finish over a carbide base metal that improves the adhesion strength of the coating layers. Newly designed blade-edge shapes maximize performance even under high-load machining.
Magic Drill DRA, is a modular drill that combines drilling accuracy with chip control. Its helix angle and flute design have been optimized to increase strength and prevent deflection. Drilling accuracy is achieved by reducing the cutting force through a special S-shaped chisel edge that minimizes thrust and vibration during drilling.

- chemical vapor deposition ( CVD)
chemical vapor deposition ( CVD)
High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.
- cutting force
Engagement of a tool’s cutting edge with a workpiece generates a cutting force. Such a cutting force combines tangential, feed and radial forces, which can be measured by a dynamometer. Of the three cutting force components, tangential force is the greatest. Tangential force generates torque and accounts for more than 95 percent of the machining power. See dynamometer.
- cutting tool materials
cutting tool materials
Cutting tool materials include cemented carbides, ceramics, cermets, polycrystalline diamond, polycrystalline cubic boron nitride, some grades of tool steels and high-speed steels. See HSS, high-speed steels; PCBN, polycrystalline cubic boron nitride; PCD, polycrystalline diamond.
- helix angle
Angle that the tool’s leading edge makes with the plane of its centerline.
Any manufacturing process in which metal is processed or machined such that the workpiece is given a new shape. Broadly defined, the term includes processes such as design and layout, heat-treating, material handling and inspection.
