Kyocera Milling Tools Provide Optimized Chip Evacuation

Kyocera introduces the MA90 Milling Series featuring four-edge tangentially mounted inserts, providing high rigidity and chip evacuation, as well as enhanced tool life and surface finishes.

Available in a variety of end mill, face mill and modular head sizes, the MA90 mills are designed for rigidity and ease of use. 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. The tangential design also allows for more teeth per diameter, better chip evacuation and larger web thickness.

When paired with the latest PR18 Series inserts, the MA90 demonstrates its capability to reliably tackle various materials. PR18 Series insert grades incorporate Megacoat Nano EX coating technology, which provides wear resistance and durability. By using a specialized double-lamination technique with special nano multilayers for abrasion, wear and heat resistance, this coating delivers optimized performance and extends the tool lifespan.

Features of the MA90 milling series include:

• Tangentially mounted inserts for greater rigidity, chatter resistance and chip evacuation
• High-quality surface finish with large axial rake and included wiper edge
• Optimized wall accuracy with precise peripheral grinding specifications
• Multi-functional designs for facing, shouldering, slotting, ramping, helical milling, pocketing, contouring and plunging operations
• Economical inserts with four cutting edges
• Easy-to-replace inserts with screws on the side
• Next generation PR18 Series Megacoat Nano EX milling insert technology for extended tool life in a wide range of materials
