Abstract

A numerically-controlled bending machine for tube or rod workpieces comprises a bend head (10, 11) including a bend former (14), collet chuck means (1) for supporting a workpiece at a predetermined position and axial orientation against the bend former, and means (14, 15) for clamping the workpiece against the bend former, the bend head being operated to rotate the bend former by a rack (13) and pinion (12) arrangement, wherein the rack includes a pre-settable mechanical stop (30) to control the extent of movement of the rack and hence the extent of bend angle. The required bend parameters are programmed into the control system using "user-friendly" language which is automatically convertible into CNC language for automatic control of the bending operation or sequence of bending operations.
