What is the principle of WEDM - WEDM processing fluid

WEDM is a kind of electrical machining machine tool, which cuts metal (especially hard material and complicated parts) by electric corrosion with molybdenum wire. Aluminum alloy cleaning agent

WEDM processing fluid, sometimes also known as wire cutting. Its basic working principle is to use continuously moving fine metal wire (called electrode wire) as electrode to remove metal by pulse spark discharge and cut and shape the workpiece. It is mainly used for processing various complicated and precise small workpieces, such as punch, die, die, fixed plate, discharge plate of blanking die, metal electrode for forming tool, template, EDM, various micro holes, slots, arbitrary curves, etc. it has the outstanding advantages of small machining allowance, high machining accuracy, short production cycle, low manufacturing cost, etc, At present, WEDM machine tools at home and abroad account for more than 60% of the total number of EDM machines.

According to the different running speed of electrode wire, WEDM machine tools are usually divided into two categories: one is WEDM-HS, which makes high-speed reciprocating motion of the electrode wire, and the general wire speed is 8 ~ 10m / s. the electrode wire can be reused and the processing speed is relatively high. However, the fast wire feeding is easy to cause electrode wire shaking and pause in reverse direction, which makes the processing quality decline The main types of machines produced and used in China are also the original WEDM mode in China; The other is WEDM-LS, whose electrode wire moves in low speed and unidirectional direction. Generally, the wire speed is lower than 0.2m/s, and the electrode wire is no longer used after discharge. It works smoothly, evenly, with small jitter and good processing quality, but the processing speed is low. It is the main type of machine produced and used at home and abroad.
