How much does the Gleason P 800G cost?
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 P 800G is a gear grinding machine with an 800 mm (31.50 in) table, a maximum workpiece diameter of 800 mm (31.50 in) and a table load of up to 3,000 kg (6,614 lb). The smallest module Gleason lists is 2 mm.
Load is the number to plan around. Gear, arbor and clamping equipment all count toward the 3,000 kg (6,614 lb), and on a wide-faced gear near full diameter the fixture can take a noticeable share of it. Because table and workpiece carry the same 800 mm (31.50 in) figure, a full-size gear rests on a table as wide as itself.
A further set of rows reads workpiece diameter up to 1,000 mm, profile depth up to 80 mm and axial travel up to 1,000 mm. The 1,000 mm diameter is larger than the 800 mm (31.50 in) maximum stated elsewhere in the same table. Whether it describes an extension or a different configuration is not stated, so get the diameter limit in writing for the machine on offer.
At the fine end, a 2 mm minimum module rules out small-pitch gears. The table sets no maximum module and has no spindle speeds or machine weight.

Strengths & Limitations
Strengths
- Table load of up to 3,000 kg (6,614 lb) for heavy gears with their fixtures
- Table diameter of 800 mm (31.50 in) equals the maximum workpiece diameter
- Axial travel of up to 1,000 mm is listed for long tooth widths and shafts
- Profile depth of up to 80 mm is listed
Limitations
- Minimum module is 2 mm, so fine-pitch gears are out of range
- The 800 mm (31.50 in) and 1,000 mm diameter rows disagree and need clarifying
- No maximum module, spindle speed or machine weight is listed

Frequently Asked Questions
01
Up to 3,000 kg (6,614 lb). That figure has to cover the gear, the arbor or fixture and any clamping equipment together. The table itself is 800 mm (31.50 in) in diameter, the same as the maximum workpiece diameter.
02
The table states a maximum workpiece diameter of 800 mm (31.50 in), and a separate row gives a workpiece diameter of up to 1,000 mm. The rows do not explain the difference, so confirm with Gleason whether the larger figure applies to the machine you are quoted.
03
Gleason lists a minimum module of 2 mm. No maximum module is given in the table, though a profile depth of up to 80 mm is listed, which indicates the depth of tooth form the wheel can reach.
