The WEDM The principle and classification
WEDM (Wire cut Electrical Discharge Machining W EDM), it is an electrical machine tools, through the galvanic corrosion by molybdenum wire for cutting metal (especially hard materials, rows and complex parts, at the same time, the use of high energy density power spark discharge ablation in principle be processed.
Principles of WEDM
(1) NC WEDM machining, cutting tool (copper or molybdenum wire) between the workpiece and a 20kHz, 150V DC pulse voltage. Pulse discharge between the wire electrode and the workpiece. When the distance between the tool and workpiece are close enough (about 0. 01 mm), the voltage breakdown cooling cutting fluid medium, the full length of the cutting machine cutting tool and workpiece near uniform discharge, high energy density EDM instantaneous temperature up to 7000 ° C or higher, high temperature so that the instantaneous vaporization of the metal to be cut, the formation of metal oxides melt in the cutting fluid, and moving the wire cutting tool with a machining area.
(2) wire electrode along the axial (vertical or Z direction) to go wire movement.
(3) The wire electrode with respect to the workpiece in the X, Y plane as CNC motion
WEDM Category
(1) high-speed WEDM wire bed (WEDM-HS), the electrode wire for high-speed reciprocating wire speed 8 ~ 10m / s, the electrode wire can be reused, higher processing speed, but fast walking wire likely to cause the electrode wire jitter and reverse pause, so that the processing of decline in the quality of production and use models.
(2) low-speed WEDM wire bed (WEDM-LS), the electrode wire for low-speed one-way movement, generally take the wire speed is less than 0. 2 m / s, the discharge of the electrode wire is no longer used, smooth, uniform, jitter, better quality of processing, but the processing speed is low, production and use of foreign models.
(3) speed to go wire WEDM, also known as "thread cutting away. " Our original The principle is repeatedly cutting the workpiece, beginning with faster wire cylinder speed, strong high-frequency cut, the final cut with slow wire cylinder speed, weak high-frequency current wiper, thereby improving the processing finish.
