Product Description

High accuracy DK77 series high speed wire cutting machine DK7750

1. 1. The WEDM is composed of main machine, electrical control system, software and cooling filter system. The main machine is mainly composed of fuselage, column, wire frame, workbench, etc. the structure of the machine tool is compact and the design is reasonable. It has five axes of X, y, u, V and Z, among which the four axes of X, y, u and V are linked and driven by step without resistance and constant current. The vertical cabinet dqe-ds-03 (full step type) of the electrical cabinet is made of cold-rolled steel plate, with electrostatic spray molding. The interior is equipped with computer and control software, high-frequency control module, driver, frequency converter, fan, etc. The cooling system includes water tank, cooling pump and filter screen.
