MACHINING CENTER

摘要

The machining centre comprises a drive for moving a work table (1) on a machine bed (2) in the direction of X- and Y-axes, and a machining unit (9). The machining unit includes a spindle (10) having a chuck (14) to the tip of which various tools and discharge electrode can be fitted, a motor (15) to rotates the spindle and a brake (12), stops it. A device is included for moving the machining unit (9) in the direction of a Z-axis. An automatic tool changer (18) keeps the various tools and the discharge electrode and selectively supplying them to the chuck. A machining power source (22) is connected to a discharge electrode (26) or a grindstone fitted to the chuck (14) and to a work (4) in the liquid tank or a nozzle for a coolant and applies a D.C. current to them.
