刀具结构如图所示,主要由主刀体、副刀体、倒角刀、冷却润滑管路等组成。用于C620车床上,精加工齿轮泵体类零件,一次纵向进刀即可车出。由于刀具角度选择合理,冷却润滑液充足,所以,刀具排屑流畅、磨损小,可保证加工精度和光洁度((?)7左右),使加工效率提高6～7倍。刀具的调整与使用:1.将刀具压紧在车床方刀架上,使其小孔刀2的4毫米修光刃与工件轴线平行;2.将泵体小孔车至公差范围,然后,锁紧大刀架斜铁;
Tool structure as shown, mainly by the main cutter body, Vice cutter body, chamfering knife, cooling lubrication pipe and other components. For C620 lathe, finishing gear pump body parts, a longitudinal feed can be car. As the choice of a reasonable tool angle, cooling fluid sufficient, so the tool chip fluff, wear small, can ensure the processing accuracy and finish ((?) 7 or so), so that processing efficiency increased 6 to 7 times. Tool adjustment and use: 1. The tool is pressed on the lathe side of the turret, so that its small hole knife 2 4 mm wiper parallel to the axis of the workpiece; 2. The pump body hole to the tolerance range, and then, Locking large turret oblique iron;
