轴承座以往采用普通的内孔刀进行粗精车加工,加工出的轴承座内孔尺寸精度差,粗糙度满足不了要求,只能用砂布打光,生产效率低。如内孔改用磨削加工,则生产效率更低,制造成本也要增加。为此我们设计了一套浮镗装置,改轴承座精车为浮镗加工。通常在车床上镗孔,镗刀杆固定安装在刀架上,镗刀杆安装在刀架上的缺陷是,镗刀的刚性差、容易
In the past, the ordinary bore hole cutter was used for the rough finishing machining. The precision of the bore dimensions of the bearing seat machined was poor. The roughness could not meet the requirement. Only the abrasive cloth could be used to light and the production efficiency was low. If the hole to use grinding, the lower the production efficiency, manufacturing costs have to increase. To this end we have designed a set of floating boring device, change the bearing fine car for floating boring processing. Boring is usually boring on the lathe, the boring bar is fixedly mounted on the tool holder, and the defect that the boring bar is mounted on the tool holder is that the boring tool has poor rigidity and is easy
