<p>The spark erosion machine is used for cutting dies and has an electrode (2) mounted on an arm (3) which can move up or down or can be locked by the device (1) in any required position. Instead of moving the electrode (2) sideways, the workpieces (4, 5) are mounted on slides (6, 7) which can move laterally. This lateral motion is controlled by servo-motors (10, 11). The spark erosion machines can achieve a much higher degree of accuracy than conventional designs and is esp. for cutting the separate halves of a split die.</p> |
