Product Name: A-type cylindrical carbide rotary file Detail Grain: Single cut Main Uses: Tungsten steel grinding head is widely used in machinery, aviation, automobile, shipbuilding, chemical industry, process engraving and other industrial sectors, the effect is remarkable. (1) Finishing various metal mold cavities, such as processing shoe molds and so on. (2) Various metal and non-metal craft carving, such as mold carving, craft gift trimming. (3) Clean up the flash, burr and weld of casting, forging and welding parts, such as machine casting factory, shipyard, automobile factory. (4) Chamfering and groove processing of various mechanical parts, cleaning pipes, finishing the inner hole surface of mechanical parts, such as machinery factories, repair shops. (5) The polishing of the impeller runner, such as the automobile engine factory. Tungsten steel grinding head mainly has the following characteristics: (1) Can process a variety of metals (including hardened steel) and non-metals (such as marble, jade, bone), processing hardness up to HRC70. (2) In most of the work can replace the small wheel with a handle, and no dust pollution. (3) High production efficiency, dozens of times higher than the processing efficiency with file, nearly ten times higher than the processing efficiency with a small wheel with a handle. (4) The product processing quality is good, the finish is high, and the mold cavity of various shapes can be processed with high precision. (5) Long service life, ten times higher than the durability of high-speed steel tools, more than 200 times higher than the durability of small grinding wheels. (6) Easy to use, reliable, can reduce labor intensity, improve the working environment. (7) The economic benefits are greatly improved, and the comprehensive processing cost can be reduced by tens of times. Tungsten Steel Grinding Head: Mainly used in pneumatic or electric drive tools, the speed is generally 6000-50000 RPM, when using the tool clamping clamping, cutting mode is good to avoid reciprocating cutting, working should prevent the chip flying.
