Milling series features 4-edge tangentially mounted inserts

Kyocera says its MA90 milling series features 4-edge tangentially mounted inserts, ensuring ultimate body rigidity, superior chip evacuation, enhanced tool life, and impeccable surface finishes. Available in a variety of inch and metric end mill, face mill, and modular head sizes, the MA90 mills are designed with rigidity and ease-of-use in mind. Due to its design with tangentially mounted inserts where the insert screws are on the side, cutting forces are directed into the insert pocket corner. On conventional mills where the screw is on the front, cutting forces directed over the edge of the insert can build tension on the screw. The tangential design also allows for more teeth per diameter, better chip evacuation, and larger web thickness, giving a significant amount of rigidity to the body.When paired with the latest PR18 Series inserts, the MA90 demonstrates its capability to tackle various materials. PR18 Series insert grades incorporate proprietary MEGACOAT NANO EX coating technology, setting a new standard for wear resistance and durability, the company says. By using a unique double lamination technique with special nano multi-layers for abrasion, wear, and heat resistance, this coating surpasses conventional grades, delivering superior performance and extending the lifespan of the tools.
