1980年9月,在美国芝加哥举办了二年一次的国际机床工具展览会(IMTS′80)。现将会上展出的电加工机床介绍如下。 1、Charmilles公司的F431型电火花线切割机床能切割100毫米厚的工件,切割25毫米厚的工具钢,生产率为150毫米~2/分。机床有500×500毫米的花岗岩工作台,其基准面精度在4微米以内。最大工件尺寸为400×400×100毫米;最大工件重量可达250公斤。工作台行程250×250毫米。电极丝用兰宝石导向;通过调整V形导向器和CNC控制,可
In September 1980, the bi-annual International Machine Tool Exhibition (IMTS’80) was held in Chicago, USA. Now on display at the EDM machine described below. 1, Charmilles’s F431 WEDM can cut 100 mm thick workpiece, cut 25 mm thick tool steel, the productivity of 150 mm ~ 2 / min. The machine has a 500 × 500 mm granite bench with a datum accuracy of less than 4 microns. Maximum workpiece size is 400 × 400 × 100 mm; maximum workpiece weight up to 250 kg. Workbench travel 250 × 250 mm. Electrode wire with sapphire-oriented; by adjusting the V-shaped guide and CNC control
