Hard alloy rotary files, also known as hard alloy high-speed multi-tool milling cutters or hard alloy mold milling cutters, are used in conjunction with high-speed electric grinders or pneumatic tools. They are suitable for precision machining of various metal molds; cleaning of flash, burrs, and welds on cast, forged, and welded parts; chamfering, rounding, grooving, and keyway processing of mechanical components; polishing of the flow channels of impellers; cleaning of pipes; precision machining of internal hole surfaces of mechanical parts; and process engraving of both metallic and non-metallic materials. In developed industrial countries abroad, these tools have been widely applied and serve as an important means to improve production efficiency and achieve mechanized handwork. In recent years, such cutting tools have been gradually promoted and applied in China. With increasing user numbers, they will become essential tools for handworkers and repairmen. Their main advantages are:
1. It can process metals such as cast iron, cast steel, carbon steel, alloy steel, stainless steel, copper, and aluminum, as well as non-metals like marble, jade, and bone. The processed hardness can reach HRA ≥ 85.
2. It can basically replace a handleless small grinding wheel, and causes no dust pollution.
3. High production efficiency. The processing speed is dozens of times faster than manual filing tools, and nearly ten times faster than hand-held grinding wheels.
4. The processing quality is excellent, with high surface finish. It can produce molds and cavities of various high-precision shapes.
5. Long service life. The durability is ten times higher than that of high-speed steel tools, and more than 200 times higher than that of small grinding wheels.
6. Easy to use, simple to operate, and safe and reliable.
7. The overall processing cost can be reduced by dozens of times.
