6-axis 6-linkage EDM Small Hole Driller - MH30C


MH30C micro EDM machine tool is developed by BIEM supported by major national scientific and technology projects. It has dual functions, micro forming and small hole drilling. The lathe has X/Y/Z/W four full closed loop control linear axis(positioning accuracy 2μm, repositioning accuracy 1μm ), and U/V two full closed lop control high precession dividing rotating shafts, and one R axis with adjustable speed. Axis W adapts linear motor structure, has high positioning accuracy, strong servo capability, all of which have greatly enhanced the performance of processing small holes. By 6 axis linkage motion, it can realize processing of spark micro holes in complex spatial position. Spark micro machining power supply is stable, efficient and reliable. It can process small holes ranged between Φ0.1~0.3mm.


Small hole processing minimum electrode loss ≤0.05%;
Best processing surface roughness Ra≤0.05μm;
Minimum diameter of processed circular hole Φ0.08mm;
High precision copy electrode can be realized, capable to process small holes on tiny parts and complex surface, micro-hole contour burr-free and sharp-edged.
Aqueous medium processing lathe can be provided according customer demand
