3 models in the Coma family are documented on this 48-station layout — which means a turret job on one is, mechanically, the same job on the others.
Tool sizes on this turret, with the number of keyed stations in the final column.
Every station bore on the turret, at its true position, numbered as Amada numbers it. Bore positions, bore sizes and number placement are read straight from the factory layout sheet (coma 46 48 52 STATION_20260901_0001 p.2); the station numbers and tool sizes are cross-checked against two separate records before this drawing is built. Stations are grouped, not evenly spaced — that grouping is real and it is how you recognise your turret. Hover or tap a bore for its size.
| Size | Tool diameter | Stations | Of which keyed |
|---|---|---|---|
| A | 1/2 in | 18 | 6 |
| B | 1-1/4 in | 20 | 10 |
| C | 2 in | 4 | 4 |
| D | 3-1/2 in | 4 | 4 |
| E | 4-1/2 in | 2 | 2 |
| Total | 48 |
Turret type: Legacy turret; type not stated. Fixed stations and auto-index stations are listed separately above; together they make the 48-station total.
Every station on this turret by number and tool size. If you know the station you are tooling, this tells you the size that fits it. Auto-index stations are outlined.

Each row is a model documented on this layout, with the factory source and page it was verified from. 3 of 3 have a model page on this site.

Every figure above comes from an Amada document held in TSI's technical library. Nothing here is inferred from a model number.
The same model number was sold with more than one turret, so the station count has to be read off the machine rather than assumed. Send us the serial plate — a photo and where you found it — and we will tell you which layout you have and how many stations that means.
