Welcome to NEUAR EDM

Core technology of EDM

New AE II discharge power system breaks through old machining limits, which means faster cycle time, better surface finish, and lower electrode wear.

Z axis fast jumping speed 18M/min

The new AE II type motion control algorithm improves debris removal speed. The spindle can reach high-speed movement of 18M/mm to remove debris, which is nearly 9 times faster than the original AI model. In large-area and precision machining discharge occasions, stable servo motion control is provided to improve discharge efficiency and shorten machining time.
