High-Feed Milling Cutter Resists Vibration

The MFH-Raptor high-feed milling cutter from Kyocera Industrial Ceramics features a vibration-resistant design for increased productivity in ramping and helical milling at high speeds. The cutting tool has a convex helical edge design to reduce cutting forces during initial workpiece contact, and offers coolant holes for machining high-temperature alloys or improving surface roughness. Inserts are available for general milling, large depth-of-cut operations ranging to 5 mm, and wiper edges for roughing and finishing, even in low-horsepower operations. The cutter is suitable for applications such as face milling, shouldering, slotting, ramping, helical milling and plunging.

Inserts are available in various grades for difficult-to-cut materials and provide stability to help prevent insert fracturing and promote high-efficiency machining. For example, the CA6535 insert is intended for Ni-base heat-resistant alloys and martensitic stainless steel, and is coated with Kyocera’s thin-film CVD coating for high heat- and wear-resistance. The PR1535 insert for titanium alloys and precipitation-hardened stainless steel uses the company’s Megacoat Nano coating for improved stability and longer tool life in milling applications.
