Carbide rotary file, also known as hard alloy high-speed mixed milling cutter, hard alloy die milling cutter, with high speed electric grinder or pneumatic tools. All kinds of metal mold cavity can be processed; To clean the edges, burrs and welds of casting, forging and welding parts; The chamfering, rounding, groove and keyway processing of various mechanical parts; Repair of the impeller passage part; Clean up the pipes; The inner hole surface of the finishing machine parts; Various kinds of metal and non - metal craft carving, etc. It has been widely used in the developed countries, which is an important means to improve the production efficiency and realize the mechanization of the fitter. In recent years, this kind of tool has been gradually popularized in our country, and with the increasing number of users, it will become a necessary tool for the fitter and the repairman. Its main advantages are:
1. Can process cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, aluminum and other metals, and marble, jade, bone and other non-metal. Processing hardness can reach HRA greater than 85.
2. It can basically replace small grinding wheel with handle and no dust pollution.
3. High production efficiency. The processing efficiency is ten times higher than the manual file, which is nearly ten times higher than the small grinding wheel with handle.
4. Good processing quality and high finish. Can process various high - precision shape mold cavity.
5. Long service life. It is ten times more durable than high speed steel and 200 times more than small grinding wheel.
6. Easy to master, easy to use, safe and reliable.
7. Comprehensive processing costs can be reduced by tens of times.
All must be known by household.
