ID Expansion Clamp
The ID expansion clamp is 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 proper fit. Often times the clamps can be remachined for different size jobs.
    • Body Material Mild Steel
    • Low Profile
    • Ideal for Secondary Operations on Lathe Parts
    • Easily Machined to Size on Lathe or Mill
    • Excellent for Palletized Setups
    • Allows More Parts Per Workcube or Fixture Plate
    • Tighten with Hex Key or Hydraulic Pull Cylinders (Drill clearance hole for longer bolt into hydraulic cylinder)
    • Instructions included with each clamp
