Naissance Course of Zhongyuan medium-feeding wire-cut machine
December, 2004

In 1999, Zhongyuan Machine invested on building Zhongyuan NC System Institute; In 2000, Stepping into the researching process of enhancing workpiece finish by adjusting thread advancing bucket speed (Zhongyuan is the earliest factory of processing this researching.); In September of the year 2001, bring out a machine, the thread advancing bucket of which is controlled by transducer----paving the innovative way of controllable thread advancing bucket; In July, 2002, based on this type, they introduced another type machine—PLC-controlled Machine Electric Appliance System, by which ZHongyuan became the first factory to realize the numerical of quick-feeding wire-cut machine electric appliance; In March, 2004, High-speed high frequency system equipped with Zhongyuan complete numerical display and numerical control machine was pushed out, which provide the basis for the naissance of medium-feeding wire-cut machine; December of 2004, Numerical new-style wire-cut machine system—which is in medium-feeding wire cut, times cut, high frequency and can set index at random—having declaring national inventing patent.

1) Workpieces which cut and finished by this system enjoy following advantages:
A, High-precision: ±0.05mm
B, Finish approximates to slow-feeding wire （≤1μm）
C, The velocity of first cutting can reach 200m㎡
D, Workpieces incised by three times, then average cutting velocity will be up to 70m㎡/min

2) Our Target
Exploiting out an original CNC wire-cut machine which can really replace slow-feeding and cost much less, and doing favor for our national industry so that it can stand at the summit of World Technique.
