Why Granite ?

There are a number of reasons granite offers advantages over polymer concrete structures:

  • Granite can be manufactured to exceedingly close tolerances, in particular flatness. In order to achieve accuracy, a translator must have an excellent trajectory. The single most significant contributor to accuracy is flatness of trajectory.
  • Modern fabrication techniques permit intricate shapes, geometry and configuration to be created in granite materilal.  This is a rapid process with material removal form solid monolithic slab.
  • Superb surface finish and appearance
  • Long term stability
  • As opposed to polymer castings, no mold cost are incurred.
  • Leadtimes are short.
  • Depending on the granite material selected, excellent vibration damping with short decay times. Much better than any metal and similar to polymer castings.
  • Granite is a relatively light material; the density is about the same as aluminum alloy.

Granite are the preferred structural material for applications like :

    • Structures for Laser cutting machines
    • Long travel granite stages with high linear trajectory requirements
    • Fixed Gantries with high precision requirements or high accel/decel motion [ the mass of the granite assists in damping and impact absorption]
    • High Speed Moving Bridge Gantries with high accuracy and or flatness requirements
    • Multi Axis Micro Machining Centers for laser technology
