GR 600 Twin
NC engraving machine



One mastermind, four hands...
This engraving machines innovates on all fronts: design, user comfort and, above all, a totally new engineering concept. Instead of the usual NC system, the GR 600 features a central control terminal equipped with an industrial PC, for powerful intelligent control. This computer technology simultaneously controls two independent machining units, each consisting of two high-speed spindles. One of these spindles is retractable, allowing consecutive numbering of each part despite simultaneous production.

Almac GR 600 Twin NC engraving machine Economic and ergonomic
The considerable economic advantage derived from this unusual architecture is enhanced by the machine's compact footprint and optimal user comfort. With its innovative design, the GR 600 is easily integrated into dedicated work environments.

Consecutive numbering
of parts produced in double pairs! This innovative achievement underscores the success of the GR 600 twin spindles. Combined with powerful computer control software, this device allows sequential engraving of elements with incremental alphanumeric coding, which identifies each part individually. All the rest of the engraving is carried out in tandem, providing unparalleled productivity.

Simultaneous clamping
The GR 600's impressive output can be further enhanced by the addition of an optional rotary transfer table with background clamping.

  • Exclusive advantages:
  • high-performance computerised control
  • a single control unit, with two double production units
  • loading carried out concurrently with other operations
  • outstanding precision and machining quality
  • rapid return on investment
  • user comfort and intelligent design, compact footprint.
  • Options
  • spindle module
  • retractable spindle
  • 4th axis dividing head
  • automatic tool presetting
  • oil mist extraction
  • tool breakage detection
