Tungsten Carbide File

Tungsten carbide file is suitable for mold repairing, polishing and the products with high requirement to grinding precision and durability. It plays an important role in burrs removing and improving the fineness of the surface, which can be widely used in metal works, die-casting plant, refrigerator, washing machine, motorcycle, automobile and other large mold polishing. There are some advantages of tungsten copper file as follow:
1. It can be used in cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum and other metals, and marble, jade, bone and other nonmetal machining;
2. Basically can replace small grinding wheel and no dust pollution;
3. Improve the efficiency ten times than hand file;
4. High quality, fineness, can process diverse mold cavity with high-precision shape;
5. Long service life, ten times longer than high-speed steel tool.

In addition, it should be noticed when using tungsten carbide file:
1. Fracture shape: Choose the fracture shape according to the shape of filed parts; when filing the inner circular surface, to select the file or semicircle round file (small diameter workpiece); when filing the surface of inside corner, to select triangular file; when filing the right angle of inner surface, you can choose flat file and square file.
2. Tooth width: Choose according to the margin, the accuracy and the material of the workpiece. Coarse teeth rasp suitable for processing large margin, low dimensional accuracy, geometric tolerances, and surface roughness values large, soft material of the workpiece;
3. Tooth profile: The tooth profile pattern should be chosen according to the materials. When filing aluminum, copper, mild steel and other soft material of the workpiece, the best selection of single-tooth pattern file. It has large rake angle, small wedge angle, large chips flute, sharp cutting edge and other advantages.
