When high precision lathe processing large quantities of the eccentric workpiece can be manufactured a special lathe fixture clamping and machining eccentric.

Will be placed on the workpiece with eccentric sleeve openings clamping jaw self-centering chuck; sets the workpiece in the eccentric shaft with flat key for axial fastening nut. The lathe of this form can be processed at one time a plurality of workpieces, the live center support when necessary, can be used.

For large eccentric workpiece clamping available faceplate, plate bending and V-shaped block.

Clamping processing between the two top

Two top clamping eccentric workpiece, is turning the eccentric shaft, and a common clamping form of the crankshaft. Lathe eccentric shaft workpiece, as long as both ends can drill the center hole, there are heart-shaped collet clamping position, can be in this form. Lathe such a clamping way is characterized by: as long as the machining accuracy of each corresponding to the center hole, without rope positive, the eccentricity of the machining accuracy can be guaranteed. The main steps of the lathe machining operation is:

1) bar stock or forgings maximum size of the diameter or the diameter of the maximum size of the contour of the car into the optical axis, both ends of the surface car level.
2) crossed. Press crossed procedures to identify a datum across the axis of the center and the axis of the center of the eccentric surface played like red eye.
3) both ends of the mutually corresponding center hole drilling with a drilling machine or boring machine.
4) with the two top and heart-shaped clip mounted on the spindle or tailstock, step by step, segmented ministries diameter and side cutting.
