DK7740 T-Type Servo Fully Enclosed Protection CNC Wire EDM Medium-Speed Cutting Machine

1. Machine tool bed: adopts T-type duplex box overall structure; the main load-bearing structure support ribs connect the carriage, wire rack, wire transport reference surface, forming a stable whole of multiple combined T-type lines, surfaces, and bodies, plastic sand casting-ensures the rigidity and stability of the overall machine body, and the flatness of the reference surface is guaranteed in dynamic and static conditions, which increases the load weight of the machine body bearing surface.
2. Workbench carriage part: The carriage adopts a concave and convex solid, field-shaped reinforcement rib structure, plastic sand casting-stable organizational structure, not easy to produce shape errors (deformation). The ball screw and linear guide are designed to be installed on the same base reference plane to improve assembly position accuracy and eliminate assembly errors (.
Wire rack part: The column uses a C-type box structure. The upper part of the C-type column (upper wire rack) and the lower wire rack body are relatively fixed wire racks, which are rigid and not easy to resonate; the numerical compression spring mechanism of the wire wheel assembly ensures the balance tension of the molybdenum wire; the square guide rod lifting mechanism uses a worm gear, a helical gear mechanism and a 900V guide, and a V-shaped slider to tighten and lock, which can reliably and conveniently adjust the cutting height (electrically); the upper water spray device consists of a water spray plate and a wire guide, which is connected below the square guide rod to stabilize the vibration of the molybdenum wire and assist the upper water spray plate in completely spraying the coolant on the processing part.
