anywhere on the overarm. Small arbor supports give additional clearance below the arbor supports when small

diameter cutters are being used. Small arbor supports can provide support only at the extreme end of the arbor, for

this reason they are not recommended for general use. arge arbor supports can be positioned at any point on the

arbor. !herefore they can provide support near the cutter, if necessary. !he large arbor support should be

positioned as close to the cutter as possible, to provide a rigid tooling setup. "lthough arbor supports are notclassified, a general rule of thumb can be used for arbor selection##the old reference type " is of a small bearing

diameter, and the old reference type $ is of a large bearing diameter.
