Ball nose milling cutter ECRB-PN

solidroughingfor stainless steel

Enables machining of rib grooves with defined top surface widths and bottom widths on plastic molds. The following 3 sizes of rib grooves can be machined with high accuracy by reciprocating machining. Features of flute shape 1 • The R flute cross-section has the proper shape to provide both rigidity and good chip removal characteristics. • Achieves high-performance cutting with 2-flute tip and 4-flute periphery. Features of flute shape 2 ・The periphery flutes employ a 2-stage flank surface to ensure flute tip rigidity and achieve good surface roughness in high-performance cutting. Features ・A heat-resistant coating material with excellent adhesion to the tool substrate was achieved by optimizing the Al content. ・Exhibits with good wear resistance due to doping of the AlCr coating layer with Si. ・Exhibits excellent cutting life for cutting materials such as plastic molds, etc. where tool seizure often occurs. (2x the cutting life compared to conventional products.)　Provides the long life in cutting processing of materials starting with HPM-MAGIC and including prehardened steel, carbon steel, alloy steel, SUS, SKD61, SKD11, etc. ・By improving heat resistance, long life are possible for both wet cutting and dry cutting. Note) This product obtains less electric conductivity. Therefore, Please caution of using electric transmitted measuring systems.
