It is used for magnetic workholding on grinding machines, especially when flat ferrous workpieces need to be held without mechanical clamps covering the top surface. What information is needed for a quote? Send the grinder model, table size, required chuck size, workpiece material, workpiece dimensions, power supply requirements and quantity. Can this chuck hold non-ferrous materials? No. Magnetic chuck holding depends on ferrous material response, contact area, surface condition, workpiece thickness and grinding load. Non-ferrous materials are not held directly by a magnetic chuck. Request a Quote Request a quote with your grinder model, workpiece details and required magnetic chuck size.
