The Sygma™ Alpha-I 8-40 is an exceptionally versatile flange facing machine with the S-Gear™ system and an automatic toolpost. The machine clamps internally in bores from Ø 203 mm (8″) and machines flanges up to Ø 1,017 mm (40″).
Like all machines in the Alpha series, the Alpha-I 8-40 is available with different, interchangeable drives. Thanks to the modular design you can also quickly and easily convert an Alpha-I for orbital milling, with the Legacy milling unit.
Does the standard version not meet your requirements, or would you like to rent the machine for one job? Contact us; we will be happy to discuss the possibilities.
Features
Quick to set up, easy to operate
Plug & play: the machine is quickly mounted on the flange and can be operated without extensive instruction.
S-Gear™ gearbox
Five preset axial feeds; between those settings you can adjust the feed if a different finish is needed. The tool moves in both directions (feed in and feed out).
Automatic toolpost
360° rotatable, with built-in end-of-stroke limiter top and bottom.
Variable feed with presetting
Preset the feed and adjust it during work.
Multiple surface finishes
From a spiral groove (stock finish) to a smooth finish: you choose the finish that suits the gasket.
Adaptable to your application
Doesn't the standard configuration suit your job? Sygma supplies options and custom solutions; we are happy to think along.
