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 350GMS is a measuring machine for bevel-type gears up to 350 mm (13.8 in) in diameter and 100 kg (220 lb) in weight, built around a 5-axis CNC measuring head. Gleason's current lineup does not list it, and the listed figures should be confirmed on any individual machine.
The gear types row is what defines it: spiral bevel, hypoid, straight bevel and face gears. Measured parameters are profile, lead, pitch, runout, tooth thickness and surface topography. Topography is the one that matters most here, because the flank of a bevel gear is judged as a surface and not as a single profile trace and a single lead trace.
That is where the software row comes in. The table lists Gleason GEMS with closed-loop Phoenix integration, and output formats of GEMS correction files, IGES and standard gear reports. The point of a correction file is that a measured deviation goes back to the machine that cut or ground the gear, so the next part is made with adjusted settings.
The listed build is an air-bearing workpiece spindle on a granite measuring base, with integrated thermal compensation. The probe row reads touch-trigger or scanning probe. Overall dimensions are 1,800 x 1,400 x 1,900 mm (71 x 55 x 75 in). No accuracy figure is listed, and that is the first thing to ask a seller for.

Strengths & Limitations
Strengths
- Measures spiral bevel, hypoid, straight bevel and face gears up to 350 mm (13.8 in) in diameter
- Surface topography is among the measured parameters, alongside profile, lead, pitch, runout and tooth thickness
- Gleason GEMS with closed-loop Phoenix integration, with GEMS correction files among the output formats
- Air-bearing workpiece spindle, granite measuring base and integrated thermal compensation
- Listed dimensions of 1,800 x 1,400 x 1,900 mm (71 x 55 x 75 in) suit a small inspection room
Limitations
- Workpiece weight is limited to 100 kg (220 lb), which excludes heavy ring gears even when they fit the 350 mm (13.8 in) diameter
- No accuracy or repeatability figure is listed
- Every listed gear type is a bevel or face gear; spur and helical gears do not appear in the row
- The probe row reads touch-trigger or scanning probe, so which one a given machine carries has to be checked

Frequently Asked Questions
01
The listed gear types are spiral bevel, hypoid, straight bevel and face gears. The maximum workpiece diameter is 350 mm (13.8 in) and the maximum workpiece weight is 100 kg (220 lb). Spur and helical gears are not named in the gear types row.
02
Profile, lead, pitch, runout, tooth thickness and surface topography. The measuring head is listed with 5 CNC axes, and the probe is listed as touch-trigger or scanning, so confirm which probe is fitted to the machine you are looking at.
03
The software row lists Gleason GEMS with closed-loop Phoenix integration. Output formats are GEMS correction files, IGES and standard gear reports. A correction file carries the measured deviation back to the machine that produced the gear so its settings can be adjusted.
04
Listed machine dimensions are 1,800 x 1,400 x 1,900 mm (71 x 55 x 75 in). The table gives no machine weight, so ask for it before planning the floor, along with the air supply the air-bearing workpiece spindle needs.
