The basic working principle of WEDM is to use continuously moving fine wire (called electrode wire) as the electrode to remove metal and cut the workpiece by pulsed spark discharge.
WEDM is mainly used in die manufacturing, and has been widely used in the processing of template, cam, forming tool, precision small parts and special materials. In addition, some parts can be directly machined by WEDM in the trial production of motor, electrical appliances and other products, which saves the time of manufacturing stamping dies and shortens the trial production cycle.
1. Resin sand casting, high temperature tempering and vibration aging treatment are used to effectively control the deformation of machine tools.
2. Adopt imported precision linear guide and twin nuts precision ball screw to maintain mechanical accuracy for a long time.
3. Standard matching: four-axis stepping; Optional matching: two-axis or four-axis hybrid stepping motor or AC servo motor.
4. Intelligent high frequency power supply adopts the principle of slow wire discharge, which has the function of detecting and igniting, ensures equal energy pulse to process and cut, and makes the cutting efficiency, surface roughness, molybdenum wire loss and other technological indicators at the leading level in China.
5. In the process of intelligent high frequency machining, the servo tracking is adjusted intelligently according to the no-load rate and short-circuit rate of discharge.
6. Intelligent setting of high frequency processing parameters and expert database system make the processing operation simple and humane.
7. Environmentally friendly closed protection design with simple appearance.
8. The U and V axes can be equipped with linear guide and ball screw to improve the stability of taper processing.
