In terms of precision motion control technology, high-precision moving parts and closed-loop control systems improve machining accuracy. For example, the Sodick AL series uses linear motors on its XYUV four axes to achieve accurate positioning and high response; the Hanba slow wire EDM machine uses linear motor drive and grating ruler closed-loop control, achieving a repeatability accuracy of ±2μm; servo-controlled full closed-loop wire EDM machines use a servo system and a full closed-loop feedback mechanism to monitor position differences in real time to ensure accuracy. Thermal deformation compensation technology is also applied in high-precision machine tool structures.
In terms of advanced machining processes, these include precision micro-cutting, low-roughness cutting, and high surface quality machining. Unidirectional wire EDM machines embody technologies such as intelligent micro-precision pulse power supplies, multi-parameter collaborative control for corner cutting, precision micro-cutting, and low-roughness cutting. GF AgieCharmilles machines support fine-wire processes, using electrode wires as thin as φ0.03mm for ultra-precision machining, and are equipped with a dual-wire system.
