Collets For Mill Applications – Internal ID Xpansion® Clamps
The ID Xpansion clamp is the ideal way to hold multiple parts on an inside diameter for multiple machining on a vertical machining center or a horizontal machining center
These machinable clamps are produced in 10 sizes and can hold internal diameters from under 3/16ths inches to over 4 inches. They use a heat-treated, tapered screw for expansion.
The flange diameter of the clamp is held to a close tolerance for precision locating in a machined pocket on work cubes and fixture plates.
The customer machines the mild steel clamp to match the bore of the part ensuring proper fit. Often times the clamps can be remachined for different size jobs.
One of the benefits of these low profile clamps is holding many lathe parts, for secondary machining, on one compact setup. They are quickly tightened with a hex key, torque driver or can be mated to hydraulic pull cylinders for automation.
