Seco Tools' new Power 4 copy milling cutter has been developed in cooperation with customers in the power generation sector to create an optimized solution for turbine blade production. Featuring a patented anti-rotation system and a unique body design with a fully hardened nickel coating, the Power 4 offers long tool life and excellent machining results.When compared to competitive technologies, the Power 4 has proven to have a 20 percent longer tool life as well as higher productivity. The anti-rotating insert system features four facets on the insert clearance side and matching locations on the pocket seats.This keeps the inserts from rotating during the machining process, providing increased stability and security for improved quality. Additionally, the seat pockets feature a patented design that seals them to keep chips and dirt from getting inside this area. This helps to maintain the tight tolerances required for high quality machining. A Nickel Chromium surface hardening treatment has been applied to all the Power 4 cutter bodies resulting in a hardness of approximately 65 to 70 HRc. The cutters also feature internal through coolant holes. The new Powet 4 round cutters are available in grade T350M, a first choice for normal steels and an alternative for unstable conditions; and MS2500, which is a grade that is optimized for productivity and use in difficult stainless steels, super alloys and tool steels.
