Why GA-DV750

1 G acceleration

Linear direct-drive removes ball-screw inertia, slashing non-cut time on dense drilling patterns.

Optical-grating loop

Full-closed-loop feedback holds micron accuracy across the full travel.

30000 rpm HSK E40 spindle

High-speed motorized spindle for fine surface finishes.

EMI-resistant build

Suppresses magnetization and extends tool life in graphite electrode work.

Frequently Asked Questions

What does 1 G acceleration mean?
The table reaches ~9.8 m/s² — ball-screw machines cannot match this, so dense micro-hole and electrode patterns finish far faster.
Which materials can it machine?
Aluminum, steel, graphite electrodes, copper and engineering plastics for molds and precision parts.
Why is EMI resistance important?
Linear motors generate strong fields; the EMI-resistant structure prevents magnetic-pull deformation that would otherwise drift accuracy.
