Description

The ID Xpansion™ clamp is the ideal solution to hold 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 12 sizes and can hold internal diameters from under 5mm to almost 254mm. All are manufactured from 12L14 steel with black oxide coating except the largest diameter which is manufactured from 7075-T6 aluminum. 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.
