In wire electrical discharge machining (WEDM), also known as wire-cut EDM and wire cutting, a thin single-strand metal wire (molybdenum wire in this case), is fed through the workpiece, submerged in a tank of dielectric fluid, typically deionized water. Wire-cut EDM is typically used to cut plates as thick as 300mm and to make punches, tools, and dies from hard metals that are difficult to machine with other methods. The wire, which is constantly fed from a spool, is held between upper and lower diamond guides. The guides, which is CNC-controlled, move in the x-y plane. On the most models, the upper guide can also move independently in the z-u-v axis, giving rise to the ability to cut tapered and transitioning shapes (circle on the bottom, square at the top for example).
1) Machining complex shapes that would otherwise be difficult to produce with conventional cutting tools.
2) Machining extremely hard material to very close tolerance.
3) Machining very small workpieces where conventional cutting tools may damage the part from excess cutting tool pressure.
4) There is no direct contact between tool and workpiece. Therefore delicate sections and weak material can be machined without any distortion.
5) A good surface finish can be obtained.
6) Very fine holes can be drilled.
Since 1991, GOLD SAN has exported EDM machines to 34 countries in the world. Our machines are widely applied to the production of dies and molds and other applications that cannot be achieved by standard machining methods.
Providing professional advices, support and training for clients are our core rule. We insist to satisfy every customer not only with our productive machines but also our sincere services.
GOLDSAN'S factory is located in Jiangmen Industrial Park, China, which is conveniently located 90 minutes driving from Guangzhou Baiyun airport. Customer support is handled by experienced engineers and all support calls and emails are documented and entered into a CRM database resulting in highest degree of customer satisfaction.
