The ID Xpansion™ Clamp is the ideal way to hold multiple parts on an inside diameter for machining on your VMC or HMC. These machinable clamps are produced in 12 sizes and can hold internal diameters from 0.160 to 9.85.
• 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 Plates
• Clamp Body Made of Mild Steel for Machinability
• Tighten with Hex Key or Hydraulic Pull Cylinders
• Longer screws are available for hydraulic applications (pull cylinders) Model #00 - #6 ID Xpansion® Clamps
• Expand clamp approximately 0.002" to 0.003" (0.1mm) over relaxed diameter and machine to fit workpiece bore, either on lathe or mill.
• If machining the clamp on lathe use the nut provided on the back of the clamp to tighten the tapered screw. This nut is used only while machining 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 0.005" to 0.025" (.2 to 0.5mm) depending upon size. Model #7 - #10 ID Xpansion® Clamps
• Locking ring provided to ensure segments remain rigid while machining clamps to size.
• 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.
