Applications
Round vacuum chucks are used to hold and secure workpieces during surface grinding, lapping, and precision machining operations. The perforated design creates a vacuum seal when connected to an external pump system, allowing flat or contoured parts to be held securely without mechanical clamping. Commonly used in tool rooms and manufacturing facilities with centralized vacuum systems.
This OS Walker AXM-13973-1 20" Round Vacuum Chuck has been inspected and shows surface rust across the perforated top face, as clearly visible in the photos. The rust appears moderate in coverage — spread across most of the working surface — and would likely require cleaning or surface preparation before use. The side wall and rim are also showing some discoloration and patina consistent with age and storage. This unit was not tested at our facility. Please view our photo set and contact us if you have any questions.
