Abstract

This invention relates to the field of ball valve manufacturing and processing technology, specifically to a cutting device for ball valve processing, comprising: a machine tool body, on which a three-jaw chuck and a tool post are mounted, a cutting tool is mounted on the tool post, a chip removal and tool stabilizing mechanism is disposed on the tool post, and a reversing clamping part is disposed on the machine tool body and the three-jaw chuck. The reversing clamping part is adapted to remove the workpiece from the three-jaw chuck and, after reversing its direction, fix the workpiece again on the same axis to accurately rotate the workpiece. During the reversal process, the workpiece is always fixed in the same axis. Even if reclamped, it can ensure that the axis of the workpiece is always in the same straight line, ensuring coaxial multiple clamping, thereby effectively avoiding repeated positioning errors and ensuring the accuracy of subsequent cutting processing.
