A fully automatic precision hydraulic expansion chuck in the best GDS quality
GDS developed the ALLIGATOR series especially for tool grinding, and it’s an innovation in the field of precision hydraulic clamping.
WALTER users will enjoy the fact it’s a pull to clamp system, making it easier to setup than competing hydraulic chucks. It’s also sized to work on a Helitronic Essential equipped with a top loader, as you can see in this video.
The ALLIGATOR’s outstanding damping properties, combined with its precise concentricity and repeatability, enable the production of tools with the best surface finishes and dimensional accuracy.
