GMT CMM – the indigenous advantage
As a manufacturer you know the importance of dimensional and tolerance verification measurement. GMT Coordinate Measuring Machine’s (CMM) dimensional measurement capabilities include, perpendicularity, parallelism, position, angularity, profile of a surface, profile of a line, straightness, flatness, circularity (roundness), cylindricity, symmetry, total / circular run out concentricity and datum qualification.

The GMT CMM is the culmination of decades of experience in metrology and machine tools. These CMM’s combine accuracy with functionality and practicality and are the ideal measurement systems for small-to-medium sized general mechanic and prismatic components.

A wide variety of accessories that are state-of-the-art and suited for all dimensional inspection tasks are available. All GMT 3D CMM’s are designed and manufactured with proven technology and come fitted with air bearings to ensure accuracy, reliability and repeatability.

The structure of the machine has been designed such that it accurate to less than 5 microns. Computer Aided Accuracy and upgradation to Direct Computer Controlled (DCC) are possible.

Dimensional stability in a wide temperature range makes granite one of the best known natural materials used in dimensional metrology. GMT has 4 decades of experience in finishing granite for this application.

Offline programming
Reverse engineering
CAD Model import capability
I++ controller compatibility
3D scanning with Renishaw SP25 and Revo 5 Axis probe system
Can be interfaced with 3D scanner
The machines are available in a wide range of sizes and designs with a variety of different probe technologies. They can be operated manually or automatically through Direct Computer Control (DCC).

Bridge type CMM with stationary table and moving bridge placed on an ergonomically designed machine table. Machine base, cross beam and Z-axis are made of rigid granite. All axis with friction free air bearings.

The drive unit and scale of the X and Y-axis are protected by a bellow. The GMT Manual CMM can be easily upgraded to the CNC version at a later date as user needs change and inspection demands increase. Individual axis locking system is provided for Manual CMM’s.

Granite Base
GMT diabase wear-resistant black Indian granite, precision lapped to grade 0 as per IS-7327-1991. More rigid, vibration resistant and temperature stable than steel. Threaded stainless steel inserts provided in granite base for easy clamping of components and fixtures.

Bridge design
Hollow granite structure design used in the bridge for greater stability. Optimized bearing design assures optimum stability of bridge for precise volumetric measuring accuracy.
