The Sygma™ Alpha-E machines do not clamp in the bore, but on the outside (OD) of the flange or pipe. This lets you machine flanges without a usable bore, right up to the centre (Ø 0). The series runs from the compact Alpha-E 0-8 to the Alpha-E 0-100 for the heaviest jobs.
The models
| Model | Max. machining diameter | Feature |
|---|---|---|
| Alpha-E 0-8 | 8″ (220 mm) | Compact, precise and versatile |
| Alpha-E 0-13 | 13″ | Good balance between portability and performance |
| Alpha-E 0-24 | 24″ | Heavy-duty, multifunctional machine with modular facing arm |
| Alpha-E 0-40 | 40″ | Powerful and flexible for large-scale work; modular, for multiple operations |
| Alpha-E 0-80 | 80″ | For extremely heavy work; modular and easy to expand |
| Alpha-E 0-100 | 100″ | The top model of the series, for the heaviest flange machining |
