DK7732 C-Type Stepper Linear guides Waterproof 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 running reference surface, forming a stable whole of multiple combined T-type wires, surfaces, and bodies, lost foam casting-ensures the rigid stability of the overall machine body, the flatness of the reference surface is guaranteed in dynamic and static conditions, and increases the load weight of the machine body bearing surface.
2. Workbench carriage part: The carriage adopts a concave and convex solid, M-shaped reinforcement rib structure, and metal mold 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 surface-improve the assembly position accuracy and eliminate assembly errors (it is difficult to ensure the shape and position tolerance accuracy of the two base carriage reference surfaces).
3. Wire rack part: The column uses a C-type box structure. The upper part of the C-shaped column (upper wire rack) and the lower wire rack body are relatively fixed wire racks, which are rigid and not prone to resonance; 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 gears, thread secondary speed change, direction change and V-shaped guide, V-shaped slider tight locking to reliably and conveniently adjust the cutting height (electrically); the upper water spray device consists of a water spray plate, a wire stopper, and a water-blocking sponge, which is connected to the bottom of 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 area.
