Electric Discharge Machining

Electric Discharge Machining (EDM), also known as Spark Erosion Machining, refers to the machining of workpieces through the galvanic action of a pulsed discharge between a tool electrode and a workpiece electrode in a certain medium. method.
Electro-discharge Machining is a kind of special processing technology. Its machine types are divided into two types: ordinary spark machines and mirror spark machines. EDM has been widely used in mold manufacturing and precision machining industries sales@zxmade.com.

EDM process can be used to machining hard-to-process superhard materials and complex-shaped workpieces that are difficult to machining with conventional cutting methods.
They are often used to process conductive materials, such as aluminum alloys, steels, stainless steels, titanium alloys, zinc alloys, magnesium alloys, copper and even Difficult-to-machine materials such as tungsten steel are used to machining complex cavities or contours.

In order to save the cost of EDM, we provide some design suggestions:
For heat sink product, the original design interior Angle is sharp, CNC process can not process in this place, need use EDM process to keep sharp edge.
There is no assembly in the internal gap of the heat sink. After changing the right angle to R angle, the CNC can be directly machined into place, do not need to use EDM process , saving processing time and costs.
Wire Electrical Discharge Machining

Wire Electrical Discharge Machining; Also call WEDM, its working principle is the use of continuous moving thin wire (called electrode wire) as the electrode, the workpiece pulsed spark discharge metal removal, cutting and forming.
Wire cutting technology is a kind of special processing, which is different from the traditional mechanical processing technology that requires mechanical and mechanical energy to remove, and mainly uses electrical energy to realize the processing of materials. Therefore, the WEDM technology is not limited by the material properties and can process any hardness, strength, and brittleness. It is a very important process in machining sales@zxmade.com.

Types of WEDM Machines
Reciprocating type High Speed Wire cut Electrical Discharge Machining WEDM-HS

Reciprocating type High Speed Wire cut Electrical Discharge Machining WEDM-HS WEDM-HS processing of its electrode wire high-speed reciprocating motion, molybdenum wire speed of 8 ~ 10m / s adjustable, the processing speed is convenient and easy to get named, its accuracy is +/-0.02mm, When in WEDM-HS processing, speed and quality into Proportional, fast speed Surface quality is rough, speed is slow, surface quality is bright, finish is generally Ra1.6-3.2, depending on the height of the part and the material.

Medium-speed Wire cut Electrical Discharge Machining WEDM-MS

Medium-speed Wire cut Electrical Discharge Machining WEDM-MS WEDM-MS processing uses high-speed (8-12m/s) wire during roughing and low-speed (1-3m/s) wire during finishing. This work is relatively stable and has small jitter, resulting in relatively high processing quality. The processing quality can be between the high-speed wire feeder and the low-speed wire feeder. The precision is +/-0.01mm. The finish is generally about Ra1.6, depending on the height of the part and the material.

Low Speed one-way walk Wire cut Electrical Discharge Machining

Low Speed one-way walk Wire cut Electrical Discharge Machining Low Speed one-way walk Wire cut Electrical Discharge Machining processing can generally use micro wire finishing with 0.03 mm electrode wire. The most important feature is high machining accuracy, tolerance within ± 0.002 mm, surface roughness Ra0.8, depending on the height and material of the part. . Therefore, the processing cost of walking wire is the highest in WEDM.

Wire cutting applications
