Vacuum Brazing of Carbide Rotary File

Cemented carbide rotary files are mainly composed of high-hardness, refractory metal carbides (WC, TiC) micron powder, and cobalt (Co), nickel (Ni), and molybdenum (Mo) as the binder. Or powder metallurgy products sintered in a hydrogen recovery furnace. “Carbides, nitrides, borides, etc. of Group IVB, VB, VIB metals, etc., are collectively referred to as cemented carbides because of their extremely high hardness and melting point.

Cemented carbide rotary files, also known as cemented carbide high-speed assorted milling cutters, cemented carbide die milling cutters, etc., are used in conjunction with high-speed electric grinders or pneumatic tools. It can finish machining various metal mold cavities; clean up the flash, burr and weld of casting, forging and welding parts; process chamfering, rounding, groove and keyway of various mechanical parts; polishing the runner of the impeller; Cleaning the pipeline; finishing the inner hole surface of mechanical parts; crafting engraving of various metals and non-metals, etc. It has been widely used in relatively developed countries in foreign industries, and it is an important means to improve production efficiency and realize the mechanization of fitter. In recent years, this kind of tool has been gradually promoted and applied in our country. With the increasing number of users, it will become an indispensable tool for fitters and repairmen.

Advantages:

1. It can process metals such as cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum, and non-metals such as marble, jade, and bone. Processing hardness can reach HRA≥85.

2. Basically, it can replace the small grinding wheel with handle, and there is no dust pollution.

3. High production efficiency. The processing efficiency is more than ten times higher than that of manual files, and nearly ten times higher than that of small grinding wheels with handles.

4. Good processing quality and high finish. It can process a variety of high-precision mold cavities.

5. Long service life. The durability is ten times higher than that of high-speed steel cutting tools and more than 200 times higher than that of small grinding wheels.

6. Easy to master, simple to use, safe and reliable.

7. The comprehensive processing cost can be reduced dozens of times.
