Vertical turning machine for holding and machining rod-type raw material, has a calibration surface on the workpiece table for calibrating the workpiece position prior to machining

摘要

Vertical turning machine, e.g. a drill, with a workpiece holding device (26) arranged above a workpiece table (10) on which a workpiece (24, 24') is placed. The workpiece holding device is formed as a hollow clamping spindle, partially hollow spindle or a jaw chuck for holding a rod-shaped workpiece. The workpiece table has an elevated calibration surface (34) with which the part of a workpiece extending from the holding device can be defined position-wise relative to the work piece holding device. An Independent claim is made for a method for machining rod-type raw material in a vertical turning machine.
