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.
