Description

These machinable ID Xpansion Clamps are produced in 12L14 steel with black oxide coating in 12 sizes and can hold internal diameters from 4.1mm to 250mm. The #10 ID Expansion Clamp is manufactured using 7075-T6 aluminium.

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.

You can machine the mild steel clamp to match the bore of the part ensuring a proper fit. Often times the clamps can be re-machined for different size jobs, gaining multiple uses out of the same ID Xpansion Clamp over a period of time.

The low profile ID Xpansion Clamp can hold several parts in one compact area for secondary operations without any clamping interference. They are quickly tightened with a hex key, torque driver or can be mated to hydraulic pull cylinders for automation.

  • Low Profile
  • Ideal for Secondary Operations on lathe parts
  • Easily machined to size on lathe or mill
  • Excellent for palletised setups
  • Allows more parts per workcube or fixture plate
  • Heat-treated and coated screw for long life
  • Clamp body made of mild steel for machinability
  • Tighten with hex key or hydraulic pull cylinders (Drill clearance hole for longer bolt into cylinder)
  • Longer screws available for hydraulic applications

MODEL #00 – #6 ID Xpansion Clamps

  • Expand clamp approximately 0.0508mm to 0.0762mm over relaxed diameter and machine to fit to workpiece bore, either on a lathe or a mill.
  • If machining the clamp on a lathe, use the nut provided on the back of the clamp to tighten the tapered screw. So, this nut is only to be used while turning the clamp.
  • Machine a pocket, in the fixture, for the close tolerance “E” dimension and drill and tap mounting holes per “H” column. Drill and tap a hole from the “I” column in the center of the pocket for the tapered screw.
  • A recessed dowel pin may be installed into the flange for additional rigidity if required.
  • Range of expansion 0.013mm to 0.64mm depending upon size.

MODEL #7-10 ID Xpansion Clamps

  • A Locking ring is provided to ensure segments remain rigid while machining clamps to size. (#9 and #10IDs ship with 2 rings)
  • Insert ring and tighten drive screw, machine clamp to bore size. Remove ring to clamp workpiece.
  • Aggressive material removal is not recommended when machining clamps to size.
