The choice of bearing sleeve tool

by:Waxing     2020-10-06
The type of CNC lathe tool and choose the numerical control turning tool is generally divided into three categories, namely pointed tool, circular turning tool and molding tool. 当数控车床进行粗加工时,要求刀具强度高,耐用度好,以满足粗加工背吃刀量大、进给速度高的要求。 When CNC lathe precision work, choose high precision, sharp knives, high durability, to ensure the machining accuracy. For the convenience of a knife and reduce the tool installation time, try to use the machine clamp knife, the cutting tool material had better choose coating cemented carbide blade. The blade geometry structure ( Such as blade edge, geometrical angles, etc. ) According to the shape of the processed parts. Special note should be chosen when machining spherical deputy Angle cutter, avoid tool knife surface and the workpiece after produce interference. Bearing set of nc tool selection choose 45 ° carbide facing tool and facing, knife T01; Choose from 3. 15 center drill drill phi is 3. T02 # 15 at the center of the hole, the edge of the sword; Selects the phi 26 taper shank twist drill, drill base hole, knife T03; Selects the blind hole cemented carbide boring cutter coarse fine boring hole, knife T04; With 93 ° hard alloy cylindrical roughing tool coarse outside contour surface, knife T05; With 93 ° hard alloy cylindrical essence tool outside contour surface, knife T06; Choose 5 mm wide carbide cutting knife cutting thread relief groove, knife T07; Choose 60 ° threading tool carts M45 external thread, knife T08. The selected tool parameters - fill in the table 2 3 bearing sleeve in the nc machining tool card, in order to facilitate programming and operation management.
