Abstract

A means for spark erosion of workpieces. A workpiece carrier (20) and a carriage (30) including a tool support (32) are movable in controlled fashion with respect to each other along the three axes of a three dimensional coordinate system (X, Y, Z) in the work space (46) of an erosion machine (10). One of the axes (Y) of movement of the carriage (30) is parallel to the axis (A) of the workpiece carrier (20). Workpiece holds (60) of a magazine (50) are movable into the work space (46), one of them each being positioned with its axis parallel to said axis (Y) of the carriage (30) in a transfer position (P). A gripper (40) is disposed on the carriage (30), spaced from the tool support (32), for exchanging workpieces (W) between the magazine (50) and the workpiece carrier (20).
