Become Versatile

The GMS Series is equipped with high accuracy 3D scanning probes with a broad range of styli, including a stylus calibration library and optional automatic probe changer.

Measure Surfaces

GMS offers a wide range of surface roughness measurements, meeting the most common roughness parameters as defined in DIN, ISO, ANSI and more.

Employ Barkhausen

Inspect gears and other parts for surface hardness as well as residual and compressive stresses.

Get CMM Capabilities

Enjoy 3D measurement and analysis capabilties typically performed by a CMM.

Measure Gear Tools

GMS systems handle inspection of many gear cutting tools including hobs, shaper and Power Skiving cutters, stick blades and shaving tools. Depending on size, even most broaches and rack cutting tools are accommodated.

Be Fully Compatible

GAMATM 3.1 or 3.2 Applications and Control Software is fully compatible with Windows and connects easily to customers' servers. GAMA includes SPC data acquisition software and Gleason Connect® Global Support Services.
