Product Description

Longkai DK7780 Computerized Wire Cutting Machine High Precision Big Size CNC Wire-cut Machine

1.Scope of supply and purpose:
Usage: the WEDM consists of main machine, electrical control system, software and cooling filter system. The equipment is used for the discharge machining of various complex dies and parts, for the machining of various non-ferrous metals, tool steels, alloy steels and other materials. The main machine of the equipment shall have high geometric accuracy and position accuracy, and enough static, dynamic, thermal stiffness and accuracy. The equipment has the functions of taper cutting, variable taper and special meshing cutting;



2. Equipment / engineering composition and working conditions
The WEDM is composed of main machine, electrical control system, software part and cooling and filtering 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.

Long term normal working conditions of the machine:

Working environment temperature	5~40ºC
relative humidity	≤85%
Working temperature of cooling water	≤30ºC
Power Supply	380V ± 5%; 50Hz ± 1Hz; three-phase alternating current

.Color frequency converter can adjust the speed of the roller to improve the finish of the workpiece. , high efficiency (cutting efficiency can reach 10000-12000 mm2 per hour), energy saving (energy consumption of machine tool per hour is 0.85 KWH), energy saving 50% compared with ordinary machine tool, environmental protection (working fluid of high-pressure filter water tank can be changed once in 30 working days, greatly improving working time and reducing pollution discharge times
