Powerful upgrade package now available for older Gleason GMM ‘SIGMA’ Series Gear Inspection Systems

15º out. 2010

Rochester, New York, October 15, 2010— Early models of Gleason’s GMM  SIGMA Series of Analytical Gear Inspection Systems  can now  be equipped with an Upgrade Package that combines a powerful new Windows® based applications software suite called GAMA™ (Gleason Automated Measurement and Analysis) and the Renishaw® SP80H Probe to significantly improve inspection speed and performance.

Both GAMA and the Renishaw probe system are available for any of the earlier SIGMA Series systems built from 2001 to 2007 which range from the 175GMM (175 mm gear diameter capacity) to the 3000GMM (30000 mm capacity).

GAMA operating software is a Windows® based application that for the first time puts a host of features right at the fingertips of the operator in a simple, highly intuitive graphical user interface (GUI).  The time it takes to create new part inspection programs and conduct a complete analytical inspection of even the most complex bevel and cylindrical gears, is greatly reduced. 

In addition, GAMA is a true Windows® application, making it fully compatible with the latest LAN and WAN networks so that users can easily interface inspection results with their gear design and production resources for corrective actions downstream.

Other important GAMA features include: 

  • All programming/editing accomplished with simplified Windows® Applet Editor.
  • The ability to support almost any language and to easily edit language text files for localized terminology requirements.
  • The availability of configurable security levels for part origination, editing, calibration, machine configuration and network access.
  • Gear data from pre-existing part programs can be easily converted to the new GAMA-based system.


Among the most important features of the GMM SIGMA Upgrade Package is the use of a Renishaw SP80H 3-D scanning probe available with various stylus sizes, configurations and extension lengths.  The Renishaw probe provides a high speed, high accuracy measurement capability vastly superior to 2-D probe systems used by other systems.   Among its most important features are:

  • Industry-leading probe travel:  +/- 2.5 mm in the Y and Z direction, +/- 1.5 mm travel in the X axis.
  • A 20nm resolution, fully digital 3-D scanning head.
  • A kinematic probe mount system, integral to a probe crash protection system.
  • Convenient Repair-By-Exchange Program readily available through Renishaw® in all major markets.

In addition to its next-generation of GMM and GMS Series Analytical Gear Inspection Systems, Gleason Metrology Systems Corporation (formerly Gleason-M&M Precision Systems Corporation), also offers customers throughout the world’s gear production industries a host of other products including functional gages, software, automation, calibration and other services, and an A2LA Gear lab.
