CNC Auto-motion makes use of the CENTROID Axis slaving feature by driving both sides of the gantry for ultra precise positioning along with speed and power.

An 8 position rack mounted tool changer is employed for automatic tool changes.

Granite can be machined to any shape.   CENTROID's easy CNC programming allows the designers to create detailed decorative designs and other architectural details for counter tops for kitchen and bathrooms, bars, signs, tiles, monuments & memorials, and many other custom applications.
