在机夹式车刀应用中45°、90°左右车刀应用泛围广、通常采用一杆一刀方式.要实现以上操作要准备四把车刀.采用45°、90°可换位,正反机夹式粗,精车多用车刀可以在一把刀体上完成多种工序,多用车刀结构如图所示.该多用车刀的特点为:在一把刀体上可正反两面装夹刀片,每一块刀片又可在45°和90°两个位置上变换角度,组成左、右45°、90°四种不同用途的车刀对零件粗车或精车.也可根据加工材料选用YT15或YG8硬质合金.由于正反面均可装夹,即可作左车刀又可用于右车刀,实现一刀多用.该车刀结构简单装卸方便,安装牢固,使用寿命长.刀体采用45号钢加工、HRC40——45发兰处理.刀片精磨后在C618、C616车床上加工45号钢轴类零件时,车速n=610转/分,进给量C=0.25mm/转,切削深度t=0.1—4mm,效果良好.
45 °, 90 ° in the machine tool-type lathe applications wide range of application of lathe knife, usually using a knife and a knife way to achieve the above operation to prepare four lathe tool. 45 °, 90 ° transposition, positive Anti-clip type coarse, fine car multi-purpose car knife knife body can be completed in a variety of processes, multi-purpose car knife structure shown in Figure 1. The multi-purpose car knife features: the front and back of a knife body can be Clamping blades, each blade can be changed at two angles of 45 ° and 90 ° to form left and right 45 °, 90 ° turning tools for different uses on the rough or fine car parts. Also according to the processing Material selection YT15 or YG8 carbide. Because the front and back can be clamped, can be used for the left turning tool can also be used for the right turning tool to achieve a multi-purpose tool. The turning tool structure is simple loading and unloading easy to install, solid, long service life. Body 45 steel processing, HRC40--45 hair treatment.After grinding the blade on the C618, C616 lathe machining 45 steel parts, the speed of n = 610 rev / min, the feed rate C = 0.25mm / Turn, cutting depth t = 0.1-4mm, the effect is good.
