在学习外单位先进经验的基础上,我车间长期使用宽刃精车刀,对一般光轴(包括丝杠、光杠等)和曲轴主轴颈进行精加工,效果很好,现介绍给大家参考。刀具特点我们经常使用的刀片有刃长200毫米和刃长60毫米等几种。刀杆及刀片(仅以刃长200毫米的为例)如图所示。共主要特点: (1) 刀杆材料45钢(在曲部调质HRC=20～25);刀片材料为W18Cr4V;
On the basis of advanced experience of learning units, our workshop uses the long-edge precision turning tool for a long time, finishing the general optical axis (including lead screw, light bar, etc.) and crankshaft main journal with good effect and is now introduced to our reference . Knife Features We often use the blade has a blade length of 200 mm and the blade length of 60 mm and several other. Arbor and blade (blade length of 200 millimeters for example) as shown. The main features are: (1) 45 steel bar (quenched and tempered HRC = 20 ~ 25); the blade material is W18Cr4V;
