如图将滚珠轴承及切断刀具分别夹持于车刀座,可用以加速车床的工作物定长切断操作。使用时,预先调整滚珠轴承及切断刀具的相对位置,使切断的成品恰为所需长度。并调整车刀座位置,使滚珠轴承恰和工作物接触,开动车床主轴,横向送进车刀座即可 As shown in the ball bearing and cutting tool are respectively retained in the lathe seat, can be used to speed up the work of the lathe fixed length cut off operation. When used, pre-adjusted ball bearings and cut off the relative position of the cutter, so that cut the finished product exactly the desired length. And adjust the position of the lathe seat, so that the ball bearing just contact with the work piece, start the lathe spindle, cross into the lathe seat
