In order to facilitate tool setting and 63 Series Ball Bearings reduce tool installation time, try to use machine clamps. Fill in the selected tool parameters into the table 2-3 bearing sleeve NC machining tool card to facilitate programming and operation management. The tool selection for CNC machining of bearing sleeves is 45° hard alloy end face turning tool, tool number T01; φ3. T03; Use non-through-hole carbide boring tool for rough and fine boring inner hole, tool number T04; Use 93° cemented carbide outer circle rough turning tool for rough turning outer contour surface, tool number T05; Use 93° cemented carbide

The outer contour surface of the external precision turning tool is finely turned, tool number T06; the 5mm wide carbide grooving tool is used for threading undercut, tool number T07; the 60° external threading tool is used for M45 external threading, tool number T08 .15 center drill φ3.

The geometry of the blade (such as rounded corners, geometric angles, etc. Special attention should be paid to selecting a tool with a large auxiliary deflection angle when processing the spherical surface to avoid interference between the flank surface of the tool and the workpiece. When the CNC lathe is used for finishing, it is necessary to choose high-precision, sharp, and high-durability tools to ensure the machining accuracy.  When the CNC lathe performs roughing, the tool is required to have high strength and good durability to meet the requirements of a large amount of roughing back and high feed speed.

The tool material is best to use coated carbide blades.15 center hole, tool number T02; φ26 taper shank twist drill for bottom hole , Tool No. The types of CNC turning tools and the selection of turning tools for CNC turning are generally divided into three categories, namely, pointed turning tools, arc turning tools and forming turning tools.) of the blade should be determined according to the shape of the machined part. 2.
