Configurations
| The machine structure is designed via computer-aided analysis of tensile strength, compressive strength and reaction force, maintaining long-term machining accuracy | |
| Reasonable structure, non-deformable and high rigidity to ensure machining accuracy | |
| Z-axis adopts precision preloaded double-nut ball screw from Taiwan. The slide rail features V-shape and flat design, ensuring smooth sliding and high precision under heavy load | |
 | Z-axis is equipped with DC servo motor |
| Triple safety detection: infrared fire detection, liquid level control, automatic fire extinguisher | |
  | Taiwan WALRUS oil pump or Italy PEDROLLO oil pump |
 | 5µm or 1µm precision grating ruler feedback for closed-loop control |
| Optional slag removal methods: flushing oil, oil extraction, or non-immersion machining | |
| Suitable for machining copper, graphite and steel workpieces, including cavities, holes and special-shaped parts | |
| The lubrication system adopts a recycling mode; slide rail lubrication is completed in one step while keeping the appearance clean |
