#200 Sure-Grip® Expanding Collet Grinding Arbor

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.

Range

The arbors come in five sizes and will hande a range from .500" to 4" (12.70mm to 101.60mm). Nominal size Sure-Grip® expanding collets are available from stock.

Maximize Your Productivity

Use two arbors. While one part is running, load the next part on the second arbor. You can then be ready to load another 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.

Interchangeable Collets

The Forkardt Hardinge Sure-Grip Expanding Collet Systems use the same collets for the Grinding - Turning Arbor as they do for the spindlemounted and collet-style assemblies. This allows you to use one set of collets for both your grinder and lathe applications.

Mounting Collet to Arbor

Clean locating surfaces of arbor and ID of expansion collet. Coat surfaces with antiseize grease. Mount collet aligningwith key. Assemble spacer and nut. Mount workpiece (locate against work stop when used), tighten nut with sufficient force to hold workpiece while being machined.

Locating Shoulder

The arbors have a precision locating shoulder and diameter so you can fabricate custom workpiece stops.
