Wire walking method: Slow wire: one-way wire travel, non-reusable wire speed: common and basically in( 0.25 to 0.001m/s) Wire diameter: 0.003to 0.3mm
Medium wire: reciprocating wire walking, reusable wire speed: adjustable, rough machining (8-12m/s), low speed (1-3m/s) for finishing machining Diameter of electrode wire: 0.14 to 0.2mm
Fast wire: reciprocating wire reusable Wire speed: common (8-12m/s) Diameter of electrode wire: 0.14 to 0.2mm


multiple cuts Slow wire: 1-7 times with finishing power supply Roughness: 0.1μm~0.3 μm Medium wire: learn from the multiple cutting of slow wire Some high-end machine tools are equipped with intensive power supply Roughness: 0.3μm~0.8μm Fast wire: without multiple cuts Roughness: ＞1.0 μm


drive mode Slow wire: AC servo motor, linear motor, fully closed loop Medium wire: stepper motor AC servo motor (rarely use linear motor) semi-closed loop Fast Wire: Stepper Motor Open Loop
Cutting accuracy
Slow wire: 0.001~0.003mm
Medium wire: 0.005~0.01mm
Fast wire: ＞0.01mm
