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