Hard alloy cemented carbide rotary file is mainly composed of hard phase tungsten carbide and binding phase cobalt. It is also called cemented carbide high-speed assorted milling cutter, or mold milling cutter, etc. It is mainly matched with high-speed electric grinders and pneumatic tools. use. Because its machining hardness can reach above HRA85, it can be well applied in most materials, such as ordinary cast iron, cast steel, copper, aluminum, marble, alloy steel, carbon steel, and other metallic or non-metallic materials. Its working principle is to clamp hard alloy cemented carbide rotary file on a high-speed rotating tool and realize the cutting effect through pressure and feed speed it receives.
Extensive applications of hard alloy cemented carbide rotary file
Carbide rotary file has excellent cutting performance and long service life. It has a wide range of uses, such as finishing metal mold cavities; cleaning flash, burrs, and welds in castings, forgings, and weldments; Processing chamfers, grooves, and keyways of various mechanical parts; cleaning and grinding of surface of pipes, runners and inner holes of parts; carving of various metal or non-metal materials, etc.
Shape, grade, and tooth profile of hard alloy cemented carbide rotary file
According to the shape of the head, the carbide rotary file can be divided into cylindrical (A), cylindrical head (C), round head arch (F), round ball (D), round head torch shape (H), 90° Conical (K), 60°conical (J), 38°conical (M), arc disc (T), inverted cone (N), conical round head (L), conical tip ( M), waist drum shape (B), oval shape (E), arc arrow (G), conical flat head (S), cylindrical arc half head (W), etc. The commonly used grades of cemented carbide rotary files are YG6, YG8, and YG10X.
Basic Fluting Styles for Carbide Burs are as below:
Nonferrous: For nonferrous materials. Aggressive stock removal.
Coarse Cut: Provides a large flute area for softer ferrous materials. Fast stock removal.
Single Cut: General purpose fluting. Produces long chips.
Diamond-Cut: For heat treated and tough alloy steels where control is important. Creates a power-like chip. Excellent finish.
Fine Cut: For general use on hard materials requiring a fine finish.
Double Cut: Very efficient stock removal. Creates a small chip. Good finish. Excellent operator control.
Chip Breaker: Provides breakdown in chips. Better control.
