Center drive lathe machine for machining rotationally driven workpiece at two ends in single set, has tool turrets fixedly-arranged on machine frame, and chuck head movably arranged along horizontal and vertical directions

摘要

The machine has a machine frame (1), a chuck head (6) and two tool turrets (8, 8') with tools (9, 9') for cutting process. The tool turrets are fixedly-arranged on the machine frame, and the chuck head is movably arranged along horizontal and vertical directions. Machined and un-machined workpieces (7, 7') are directly arranged adjacent to each other in a loading position such that a finished workpiece is moved out from the chuck head and an unprocessed workpiece is linearly moved into the chuck head. Grippers are provided on the tool turrets for gripping the workpieces.
