摘要： A cutting-off method of an automatic lathe, comprising steps of applying a front working to a bar material by a front working tool with the bar material chucked by a main spindle rotatably supported by a headstock and with a top end of the bar material supported by a guide bush, applying a cutting-off by a cut-off tool after completion of the front working with the top end of the bar material chucked and rotatively driven by a sub spindle rotatably supported by a rear headstock, and simultaneously releasing the bar material chucked by the main spindle so that the headstock may rearwardly move to a working start position to be ready for the next working.
