The Fast Wire Electrical Discharge Machining (WEDM) machine, also
known as a High-Speed Wire Electrical Discharge Machine (WEDM-HS),
is an efficient metal cutting device. It operates by using a
rapidly reciprocating electrode wire (usually made of molybdenum
wire) with speeds ranging from 8 to 10 meters per second. The wire
can be reused, leading to high cutting speeds. Its accuracy
typically falls between 0.05 to 0.08 millimeters.
During operation, the wire is negatively charged, while the
workpiece is positively charged. When the distance between them is
less than the discharge gap, a pulse power supply generates an
electric spark, creating high temperatures that melt or vaporize
the workpiece's surface. The wire's movement and the impact of the
working fluid remove the metal, forming a groove. Since the
molybdenum wire's melting point is much higher than the workpiece
material and it moves away from the high-temperature area, the
wire's wear is significantly less than the workpiece, ensuring
precise cutting.
Fast wire EDMs are widely used in mold manufacturing, processing of
difficult-to-machine materials, and for complex part fabrication.
Especially suitable for rapid processing of large-thickness molds
or components, regular maintenance and replacement of consumables
like guide wheels and guides, as well as quality control of the
molybdenum wire and cutting fluid, are essential to maintain high
cutting quality.
In China, the development of fast wire EDM machines started in the
1960s, with the invention by Engineer Zhang Weiliang. Later, they
were commercialized in factories in cities like Suzhou. Over time,
through technological advancements such as the application of
single-board computers, innovations in working media, and the
introduction of composite working fluids, the efficiency and
surface finish of cutting have been significantly improved. Modern
fast wire EDM machines not only boast improved design aesthetics
but also enhanced functionality and environmental performance.
If you need more detailed information about fast wire EDM machines
or are looking for specific models, it's recommended to consult
professional wire EDM machine manufacturers, like Jiang Lin
Numerical Control Machine Tool Co., Ltd., who can provide
comprehensive support from equipment supply to after-sales service.
