Lathe center frame, with the main role of the tool holder is what, specific points

Center frame is mainly used for longer workpiece machining plane playing center hole,

Because the workpiece is longer lathe section fixed total length, lathe radial feed cutting workpiece can not withstand the external force vibration, can not cut,

So the design of the center frame, mounted on the guide rail to fix the workpiece, the center frame of the three contacts to contact the workpiece anastomosis support to increase rigidity, easy to cut.

Following the tool holder is mainly used to strengthen the slender axis cutting stability. It is fixed on the drag plate with the knife along with the forward, stable support for the workpiece outer circle, to prevent chattering and shaking,

Difference: 1 installation. Position is different; 2. Center frame does not move with the drag plate, with the tool holder with the large drag plate movement.
