Processing all kinds of metal: (including all sorts of hardened steel) and non-metal(such as marble, jade bone), machining hardness reach < HRC70.For the most work it can be replaced with small grinding wheel,and no dust pollution.Good machining quality,high degree of finish,can work out the high accuracy of various shapes mold cavity.Service life is long,10 times higher than the durability of high speed steel cutter, 200 times more than the small wheel durability.Convenient control,using simple,safe and reliable,reduce labor intensity,improve the working environment.Carbide rotary file generally use with handheld electric or pneumatic tool drive(can also be used in machine tool).The speed of the electric or pneumatic tools usually is 6000-50000 revolutions per minute.Uses:Cleaning trimming,veining and weld joint of casting, forging and weldment.Finishing all kinds of metal molds.Impeller passage of finishing processing.A variety of mechanical parts chamfer,round and grove processing.Inner hole surface of machinery parts finishing.The process of various metal and nonmetal sculpture.Tips:Must be clamped during using . Cutting way is better with conventional milling to avoidreciprocating feeding.Prevent scraps flying at work,please use safety glasses.
