hydraulic clamp / expandable
ID Xpansion™



  • Type:


  • Other characteristics:



The ID XpansionTM clamp is the ideal way to hold multiple parts on an inside diameter for high density machining on vertical or horizontal machining centers. It can also be used as an expanding mandrel on a lathe.

These machinable clamps are produced in 10 sizes and can hold internal diameters from under 4.1mm to over 103mm.

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 a 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 set up. They are quickly tightened with a hex key, torque driver or can be mated to hydraulic pull cylinders for automation.
