Mar 26, 2002 FORTIS arbors clamp work pieces or tools for gear grinding and hobb sharpening. High inner pressure when actuated stretches steel concentrically, providing constant clamping and vibration dampening. Total indicator run out is less than 0.00012 in. Concentricity of arbors is maintained within 0.005 mm between OD and ID. Arbors are sealed against contamination, allowing them to be used in machining applications where coolants and metal grit are present.
