Micro-Sinker EDM (VMM01-XXX)

VMM01 is an advanced 3-axis micro-sinker EDM machine designed specifically for micro-drilling and EDM micromilling. The electrode system utilizes an ultra-precision PCD double-V bearing system to accept either solid tungsten electrodes (3-6.35 mm diameter (0.118-0.25")) or smaller tungsten rods (0.125-1mm diameter (0.005-0.04")) that are held in an EDM spindle featuring a high-precision collet closer.
As an EDM micro-drill, VMM01 is capable of drilling micro-holes as small as 0.01 mm (0.0004"). This is achieved with tungsten electrodes that are 0.008 mm (0.0003") in diameter. Electrodes are ground to size either externally using a diamond wheel or by using the on-machine WEDG electrode grinder (optional).
The advanced EDM control system is G-Code based, fully 3-D enabled, and has built-in canned cycles for deep hole drilling that feature electrode orbiting and feed oscillation for improved flushing and hole quality.
