 |
The ID XpansionTM clamp is the ideal way to hold multiple 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 10 sizes and can hold internal diameters from under 4.1mm to over 103mm.
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. Often times the clamps can be remachined for different size jobs.
One of the benefits of these low profile clamps is holding many lathe parts, for secondary machining, on one compact set up. 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 Palletized 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/Speed Block
- Longer Screws for Hydraulic Applications Available
|
Clamping mill parts on two bores.

| MACHINING AND INSTALLATION |
|
- Expand clamp 1mm over relaxed diameter and machine to fit workpiece bore, either on lathe or mill.
- If machining the clamp on a lathe use the nut provided, on the back of the clamp, to tighten the tapered screw. This nut is used only to machine 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 in to the flange for additional rigidity if required.
- Range of expansion .2 to .5mm depending upon size.
