DK77 CNC edm wire cutting machines, adopts high precision V-shaped guide rail(Linear guide rail optional) and P3-grade high precison ball screw. The products have high quality, complete models, long service life and high precision. Machine specifications can be customized according to customer needs,like non-standard models DK7740(45)F,DK7750(55)F,DK7763F,DK7780F,DK77100F,DK77120F or even larger models. The company also produces ±30°, ±45°swing large taper machines and CNC high-precision middle speed edm wire cutting machines(Precision≤±0.005mm,roughness≤1.0μm). The following are the main parameters of DK77 series machines:
1.Standard maximum cutting taper:±6°/80mm;(±15°,±30°,±45° are optional)
2.Precision ≤ 0.02mm,according to GB7926-2005 standard;(If linear guide equipped, the precision can reach 0.01mm)
3.Best surface roughness ≤ Ra2.5μm(single-cut),Ra1.5μm(multi-cut);
4.Molybdenum wire diameter:0.1-0.2mm;
5.Max. cutting speed≥120mm^2/min;
6.Voltage:3 phase 380V(single phase 220V,3 phase 220V or other voltage can be customized),Power:1.5KW;
7.Working fluid:Water-based emulsion.
