Device for controlling tapping device provided with composite tool having boring and tapping sections |
摘要 |
A control device which controls a tapping device provided with a feed motor for feeding a spindle in an axial direction thereof and a spindle motor for rotating the spindle about its axis. The spindle installs a composite tool having a boring section for forming a bore in a workpiece and a subsequent tapping section for forming a female thread at the bore. An asynchronous control is initially performed for independently controlling rotation of the feed motor and the spindle motor for boring. If the tapping section reaches the workpiece, a control is switched to a synchronous control for controlling the motors in synchronism with each other.
