英国Eroda机械公司新造了两台大型电火花加工机床:N1000和N2000,主要用来加工特重特大的工件,与系列中其它机床的区別在于工作台固定不动,靠移动主轴头校正电极位置。机床的主轴头安装在重型悬臂上,后者可进行横向机动调整,并通过立柱上的数显器进行定位。悬臂全缩回时,主轴头位于工作台后缘,可方便地用吊车装卸工件。悬臂全伸出时,主轴头超出工作台前缘。主轴头下端的电极固定板可旋转90°,以便装夹电极。
Eroda Machinery Co., Ltd. of UK has newly built two large EDM machines: N1000 and N2000. It is mainly used for machining extraordinarily large workpieces. The difference between the machine and the other machines in the series is that the workbench is stationary, and the position of the electrode is corrected by moving the spindle head. The spindle head of the machine is mounted on a heavy-duty cantilever, which can be maneuvered transversely and positioned by the digital display on the column. When the cantilever is fully retracted, the spindle head is on the trailing edge of the workbench and the workpieces can be handled and handled by crane conveniently. When the cantilever is fully extended, the spindle head extends beyond the leading edge of the table. The electrode fixing plate at the lower end of the spindle head can be rotated by 90 ° to clamp the electrode.
