CNC lathe turning large hollow workpiece how to adjust the center frame?
In the turning length, diameter relatively large hollow workpiece inner hole, the end surface, the need to use the center frame. If the center frame adjustment is not good, the axis of the workpiece axis and the machine tool spindle axis does not coincide, the processing will produce end face hollow and bulging belly and hole taper error. Severe, the workpiece from the chuck in the prolapse, resulting in accidents.
When installing such a workpiece. One end of the workpiece with three-jaw chuck or four-jaw chuck, the other end, on the center shelf. And then in the hole in the workpiece plug a piece of wood or in the workpiece end with butter paste a piece of paper, tailstock tip on the top of the wood or paper, the choice of a lower spindle speed, the workpiece a week or two , Then the top of the board or paper to draw a circle, and then adjust the center frame three care, so that the center of the circle is the top of the tip, so basically the workpiece center line and the spindle axis of the machine tool Basic overlap. After semi-finishing, such as measuring the end surface flatness and hole cylindrical tolerance, and then the center frame of the three care for minor adjustments to be eliminated.
