A face cutter milling head unit has at least three linkages, driven by computer controlled servo motors, moving the drive spindle in all three mutually perpendicular axes.

摘要

The machine spindle (13) carries a cutter (14) and is supported on three linkages (8,9), pivoting (10) on slides (3) guided on rails (4) by computer (16) controlled servo motors (6) to move the spindle in any of the A, C and Z axes.
