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 300GMS Gear Metrology System is a CNC gear measuring machine with 4 measurement axes (X, Y, Z and a C rotary axis) for gears up to 300 mm in diameter and module 15. This model is not part of Gleason's current lineup, so the listed figures serve as a reference when an existing machine is evaluated.
Accuracy is stated directly: ±0.3 µm linear and ±0.5 arc-second rotary. Those two numbers decide which gear quality classes the machine can certify, since a measuring machine has to be considerably better than the tolerance it checks. Ask for a recent calibration record showing that the machine still meets them.
The probe is listed as a touch-trigger ruby probe. A touch-trigger probe takes discrete points, and the typical measurement time of 3-8 min per gear reflects that. For an inspection room sampling parts from production, the time per gear sets how many parts can be checked in a shift.
Gear types listed are spur, helical, worms, bevel and splines, a broad mix for one machine. The control is Gleason GAMA CNC, and the standards row names AGMA, DIN and ISO gear measurement. Workpiece weight, length between centres and machine footprint are not listed.

Strengths & Limitations
Strengths
- Linear accuracy of ±0.3 µm and rotary accuracy of ±0.5 arc-second are stated in the listed figures
- Gear types cover spur, helical, worms, bevel and splines
- 4 measurement axes: X, Y, Z and a C rotary axis under Gleason GAMA CNC
- Evaluation to AGMA, DIN and ISO gear measurement standards
Limitations
- The touch-trigger ruby probe takes points one at a time; no scanning probe is listed
- Typical measurement time is 3-8 min per gear, which limits how many parts can be sampled per shift
- Gear diameter is limited to 300 mm and module to 15
- No workpiece weight or length limit is listed

Frequently Asked Questions
01
The listed figures are ±0.3 µm linear accuracy and ±0.5 arc-second rotary accuracy. On an existing machine, ask for the latest calibration certificate to see whether it still measures to those values, since they depend on the condition of the axes and the room it sits in.
02
Spur gears, helical gears, worms, bevel gears and splines, up to a maximum gear diameter of 300 mm and a maximum module of 15. The table does not list a workpiece weight or a maximum length, so check those against your longest and heaviest part.
03
Typical measurement time is listed as 3-8 min per gear. The listed probe is a touch-trigger ruby probe, which collects individual points, so the time depends on how many teeth and how many features the inspection program covers.
04
The control is listed as Gleason GAMA CNC, running 4 measurement axes: X, Y, Z and a C rotary axis. The standards row names AGMA, DIN and ISO gear measurement, so reports can be evaluated against any of the three.
