Processing special aluminum cutter with large helix angle and the special treatment and the side edge tool edge is not equidistant from the design, can effectively reduce vibration and improve surface finish, ideal for the aerospace industry materials processing. Processing of high hardness materials, the use of superior high-performance milling micro grain carbide and special coating technology, tool design large helix angle and negative rake angle can be effectively processed hardness HRC62 hardened steel, high-hard steel, high strength steel and other materials difficult to machine hard steel. Unequal helix angle and variable helix milling cutter is the latest development of efficient large feed mill for processing high-life stainless steel, titanium, nickel-based alloys and other difficult materials. Molding cutter is used in Switzerland NUM's most advanced molding cutter software, CNC five-axis CNC grinding machine to complete the spiral groove, straight groove cutter forming and composite molding process, to achieve the perfect arc transition chamfer dimensions, etc. .
