3 mounting hole patterns on the base allow it to be mounted on either 400mm, 500mm, or 630mm size machine pallet with optional base plate to convert to appropriate pallet size
Tower body made from 80,000 PSI stress-relieved FCD600 series ductile cast iron
Ductile cast iron column improves overall strength, rigidity and accuracy
Bedways flame hardened to 45 HRC and jaw plate hardened to 54 HRC
Jaw plate thread size and spacing are industry standard enabling easy to find different jaw options on the market
Clamping repeatability on the vise jaw within +/-0.0002"
4 inch model delivers up to 4400lbs of clamping force and 6 inch model delivers 6000lbs of clamping force
Unique leadscrew design allows the vise to clamp on similar size or different size parts on either station
Each face on the tombstone column features 4 locating holes with a steel threaded insert to accept mounting screws from the sub plates to maintain within 0.0005" locating repeatability
Optional sub plates are precision machined and when mounted onto the tombstone column can hold tight tolerances of the overall system in terms of flatness, parallelism and perpendicularity within 0.0008"/11.81" (0.02mm/300mm)
