#250 Grinding Arbor Assembly

The Sure-Grip® Arbor assembly is designed to be used on grinding machines and lathes. The arbor can be held between centers or chucked on one end and supported by a center on the other end. This expanding arbor assembly style is manually adjusted. The arbors have a precision locating shoulder and diameter so you can fabricate custom workpiece stops. Maximize your productivity by using two arbors. While one part is running, load the next part on the second arbor. Load the second arbor into the spindle when the first part is done. This is a big time saver when chucking one end of the arbor in a collet. Sure-Grip Expanding Collets are available in 1⁄64" increments and a full range of metric sizes. The range of each collet is +.015" to -.001" (+.38 to -.025mm) from its specified size. For example, a 1.000" (25.40mm) expanding collet will hold work with a bore measuring .999" (25.37mm) to 1.015" (25.78mm), eliminating the need for decimal sizes.
