The company adds the V500 and V650 models to its Excetek line of wire cutting EDMs. According to the manufacturer, the V500’s high-frequency technology can enable users to achieve surface finish roughness of 0.2 Ra in 50-mm SKD-11 steel. The V650 features a high speed cutting module circuit and a double-door design for ease of operation. The machines are built with a high-rigidity, box-structure base designed via FEM (Finite Element Method) analysis. For cutting precision, the EDMs feature extended distance between the THK linear guideways, C1-class ballscrews with cryogenic treatment and high-resolution AC servomotors. Also included is a Windows XP-embedded control operating system, a 15" TFT touchscreen and RTX real-time extension software. Threading is done directly at the break point, with no need to return to the starting point when wire breakage occurs. Additionally, the company’s electrolysis-free generator system is intended to improve cutting performance.
