When installing such artifacts. One end of the workpiece uses a three-jaw chuck or four-jaw chuck, and the other end is placed on the center frame. Then plug a piece of wood in the hole of the workpiece or stick a piece of paper with the butter on the end face of the work piece, lean the tip of the tailstock against the board or the paper, select the lower spindle speed, and turn the work piece for a week or two. At this time, a circle is drawn on the top of the board or the paper, and then the center rest is adjusted so that the center of the circle is aligned with the tip of the top. This basically makes the centerline of the workpiece and the axis of the spindle of the machine tool. Basic coincidence. After semi-finishing, if the flatness of the end face and the cylindricity of the hole are measured to be out of tolerance, micro adjustments to the three brackets of the center frame are performed and eliminated.
Method for adjusting center frame when turning large hollow workpiece
When turning the inner hole and end face of a hollow workpiece with a large length and diameter, a center frame is used. If the center frame is not adjusted properly and the axis of the workpiece does not coincide with the spindle centerline of the machine tool, the taper error of the end face center and the bulge and hole will occur during processing. In severe cases, the workpiece escapes from the chuck and causes an accident.
