Numerical control automatic lathe

Abstract

Abstract PURPOSE: To shorten a time required for tool change by an arrangement wherein a tool to work for the next process can be indexed and selected during turning operation, and thus a stroke for tool change is limited to a longitudinal move in a short distance of a cross slide. CONSTITUTION: A given tool for a turret head 8 holding a plurality of working tools T is selected according to a command of NC. Since the tools T are positioned extremely close to a guide bush 9, they are ready for continuous turning even at the time of longitudinal feed for both guide bush 9 and turret head 8 being installed on a saddle 5. A given limit switch 47 is pushed by a given cam 45 at turning, the turret head can thus be indexed when kept from turning, and a tool to work for the next process is indexed according to a command from NC to locating.
