This WEDM machine is composed of main engine, electric control system, software and cooling and filtering system. This equipment is used for the discharge machining of the track cutting of various complex dies and parts. It is used for the processing of various non-ferrous metals, tool steels, alloy steels and other materials. The main machine of the equipment should ensure high geometric accuracy and position accuracy, and have enough static, dynamic, thermal stiffness and accuracy. The equipment has the functions of taper cutting, taper-changing and abnormal meshing cutting.
This machine adopts frequency converter, which can adjust the speed of wire drum arbitrarily, so as to improve the workpiece smoothness, high efficiency (cutting efficiency can reach 7000 to 8000 square millimeters per hour), energy saving (machine energy consumption 0.85 degrees per hour) is 50% energy saving compared with ordinary machine tool, environmental protection (machine tool environmental protection water cover to prevent working fluid splashing, using high-pressure filter tank working fluid can be replaced once in 30 working days, greatly improving the workmanship. Make time to reduce the number of sewage discharge.
"Pyramid" cross slide table structure, "T" type bed, box structure design, machine tool has sufficient static and dynamic stiffness, reliable operation, easy maintenance, in line with ergonomics principles;
All castings are cast by resin sand process, with long natural aging, secondary tempering and complete elimination of internal stress, which improves the rigidity and accuracy of castings, increases the rigidity of machine tools and reduces the amount of deformation.
All the guideways adopt high precision steel-inlaid guideways.
Ball screw is used for lead screw, which has high rolling accuracy and strong wear resistance.
Worktable and wire trawler are rolled by precise roller respectively, with small friction, smooth movement and strong wear resistance.
Machine tool components are all processed by high-end processing equipment such as large grinder and precision machining center, which ensures the geometric accuracy and coordination accuracy of parts and components.
The worktable is equipped with T-groove for easy installation and adjustment of workpiece, waterproof cover, effective prevention of saponification splash, environmental protection, beautiful and durable; the fuselage adopts environmental protection closed structure;
The barrel is welded by thin-walled seamless steel tube, which has dynamic balance detection and small static and dynamic jump. The surface is chrome-plated, durable and wear-resistant, and it is not easy to scratch.
Frequency conversion speed regulation of wire motor, smooth operation, low noise, low speed installation of molybdenum wire, safe and reliable, and wide speed regulation range
No transformer, no power resistor, no heat dissipation fan, fully enclosed structure, greatly reducing noise, equipment noise < 70dB does not send out heat; therefore, it can be more clean than other electrical appliances, not easy to damage.
High-frequency circuit uses high-performance digital pulse power supply, patent high-frequency constant current source technology, with limited peak current and short-circuit current function, reducing the probability of wire breakage. In the cutting process, it has the function of Closed-loop Detection and control, that is, detecting the discharge state and dynamically adjusting the discharge gap, which makes the cutting smooth, especially when cutting large thickness materials, the stability and reliability are more obvious.
Non-resistive constant current drive, low power consumption, energy saving and reliable;
Visual, convenient and modifiable parameter database (9 groups) allows users to flexibly save cutting parameters of different materials, different heights, different speeds and different surface roughness, as well as straightening and edging parameters. This design reduces the technical requirements for machine operators, and simplifies and facilitates the operation of machine tools.
