Do Maxx-ER centering plate feet need to be ground after installation?
Updated
Separate Maxx-ER centering plates and support feet are supplied with extra material on the feet to better the final assembly's tolerance. After installation in your fixture, the feet must be ground to 11.20 mm (+0.01/−0.05 mm) with a flatness of 0.001 mm.
Complete fixtures supplied by MaxxTooling are already ground. They do not require the same finish-grinding operation as separately purchased plates and feet.
Apply the specified screw torque without stressing the plate or threads. Avoid excessive downward Z force; the feet must be correctly ground to maintain the specified distance between the workpiece base and the feet.
