What is the maximum offset of the rear seat of the lathe?

If you want to deviate from the axis of the taper, the deviation can not be large, the length of the workpiece is different, the length of the workpiece can be large, the short point can be small, except for the degree of a few degrees The accuracy is not high, you can use this method, and the general taper processing should not be used. Mainly for the long axis degree of small small carriage travel stroke is not enough, and there is no large carriage walking and small carriage walking at the same time device of the turning mechanism, deviation lathe has a scale, the amount of deviation of processing, according to the length of the workpiece, the size of the degree is decided, the excessive chuck clamp and the top damage is large,
