ID Expansion Clamps
Jergens ID Expansion Clamps are the ideal way to hold parts on
an inside diameter for multiple machining on a vertical or
horizontal machining center. The larger 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 the clamps can be machined again for different size
jobs.
