Estimated price range
Our best estimate for a cnc gear cutting machine in this class — not a quote from Gleason. Configuration moves it a long way.
Overview
The Gleason 300 GMS is a gear measuring machine for workpieces up to 300 mm in diameter and 500 mm long, probing with an SP25 3D scanning probe. Gleason lists a module range that tops out at 18 mm and starts at 0.2 as an option, and a helix angle range of 0 to 90°.
The helix range is the figure to read first. With 0 to 90° covered, spur teeth and steep helix angles are checked on the same machine, so the limit on what can be inspected comes from diameter, length and module, not from the tooth geometry. On module, 18 mm is coarse for a part that must fit inside 300 mm, which leaves headroom at the top. The fine end is different: 0.2 is listed as an option, so small-module work has to be specified when the machine is ordered.
Workpiece length is 500 mm, with an extended Z-axis optionally available for longer shafts. Repeatability is not given in microns. Gleason states it as exceeding VDI/VDE 2612 for form measurement up to factor 5, so set that against the tolerance class of the gears you have to certify.
An Automatic Probe Changer with 6 or 9 stations is optional and earns its place where one part needs several stylus setups. The software is GAMA 3.1 / 3.2 Applications and Control Software, with KTEPS gear noise evaluation as a further option.

Strengths & Limitations
Strengths
- Helix angle range of 0 to 90°, so spur teeth and steep helical teeth are inspected on one machine
- SP25 3D scanning probe is the listed probe system, with an optional Automatic Probe Changer of 6 or 9 stations
- Module range reaches 18 mm within a 300 mm diameter capacity, and 0.2 is available as an option at the fine end
- Form measurement repeatability is stated as exceeding VDI/VDE 2612 up to factor 5
Limitations
- Workpiece diameter stops at 300 mm, and length at 500 mm unless the optional extended Z-axis is ordered
- The 0.2 lower module limit, the probe changer and KTEPS gear noise evaluation are all options, so the base machine does less than the full table suggests
- The table gives no workpiece weight limit, machine weight or footprint, so those must be requested before the inspection room is planned

Frequently Asked Questions
01
Workpieces up to 300 mm in diameter and 500 mm long. An extended Z-axis is optionally available for longer parts. The module range runs up to 18 mm, and the lower limit of 0.2 is listed as an option, so fine-pitch gears need that option specified at order.
02
Gleason lists an SP25 3D scanning probe. An Automatic Probe Changer is optional and comes with either 6 or 9 stations, which lets the machine swap stylus configurations inside one inspection program instead of stopping for a manual change.
03
GAMA 3.1 / 3.2 Applications and Control Software. KTEPS gear noise evaluation is listed as an option, so it is not part of the base software and has to be ordered if noise analysis belongs in the inspection plan.
04
Gleason does not give a micron figure in the table. Repeatability is stated as exceeding VDI/VDE 2612 for form measurement up to factor 5. Ask for the measurement uncertainty statement for your gear size and quality class before relying on it for certification.
