Kyocera Corporation announced its new MEV series of efficient, multi-functional milling cutters for metal machining applications. The new product series, which includes six inserts and 25 holders, are now available worldwide. A milling cutter typically has cutting edges on its outer holder body and bottom and is used to cut grooves and forms out of the surface of a metal workpiece. The process requires continuous improvement in cutting precision and efficiency to support the growing range of materials and applications demanded within many industries, including automotive and aerospace manufacturing. While a conventional milling cutter can deliver high rigidity and high-precision machining through increased web thickness, this often results in higher cutting forces that decreased efficiency. Alternatively, if efficiency is prioritized instead, the tool can become prone to vibration shock, which diminishes cutting accuracy. To overcome this longstanding challenge, Kyocera developed a unique "vertical triangle" insert design that delivers both high rigidity and lower cutting forces. In addition, Kyocera achieved longer product life and greater versatility by adjusting the angle of the cutting edges, increasing the rigidity of the holder body, and optimizing the insert shape to improve chip control. The web thickness of the MEV Series holder body has been increased to approximately 120 percent compared to conventional milling cutters by changing the insert orientation to a tangential mounting style for the first time among Kyocera's indexable end mills. In addition, the use of a triangular-shaped insert with low cutting resistance ensures both higher rigidity and lower cutting forces for greater machining precision and efficiency.
