The amazing new GDS Hornet
Built with extreme precision and using the same HPS collets as the µGrind super chuck, the Hornet…
- Lets you virtually eliminate both radial runout without special tools or skill
- Lets you change diameters in seconds and maintains its precision to within two microns (under a tenth) at 2½ x D without adjustment
- Maintains TIR to within 5 microns throughout the grind (assuming normal grinding forces)
- Performs like this over tens of thousands of clampings
- Requires a relatively short clamping length on the blank to achieve constant holding force and concentricity
- Features a tapered profile and smaller nose diameter than hydraulic holders for better wheel clearance and freedom from interference
- Offers excellent dampening properties for uniform material removal, optimized feed rates, excellent surface finish, and significantly reduced grinding wheel wear
- Suitable for both high production and regrinding
- Handles shanks from 3 to 20 mm (⅛ to ¾ inches). For larger tools, see the Viper
Available for:
- ANCA FX, MX, and TX machines
- Joerg machines
- Reinecker WZS 700, WZS 60 and RS 700 machines
