Working closely with clients to develop custom Xpandrels is how the full Xpandrel line was developed over the years. We have carefully selected the constituents of our standard line to ensure that many project needs can be met through standard line modification. However, it does not end there. Call us with your most challenging project needs and see what we can do for you.
Diameters Up to 15” and lengths up to 60”

The 7 Steps to Configuring Your Own Xpandrel
Understanding the finish turn: All Xpandrels require a finish turn. This is standardly 0.001 below your MMC, the Xpandrel is expanded to 0.002 over your MMC, then finished to 0.001 below MMC giving you 0.003 clearance for part on/off in the relaxed state.
1) Define Your Diameter Requirements & Tolerances
Tips: For parts with internal features, determine locations of diameter changes and desired contact areas.
Your Xpandrel can be precision ground if you require higher precision tolerances and surface finishes.
2) Define Your Working Length Requirements
Tips: For shorter length parts, determine if you want to run multiple parts at a time on one Xpandrel. For longer length parts you may need to consider all options or combinations of options for actuation methods. For more difficult blind and asymmetric parts give us a call to discuss options.
3) Define Your Total Length Requirements
Tips: Include any tooling clearance and chucking extension lengths to maximize operation with a single setup.
4) Select Your End Conditions
Tips: Another way to make your Xpandrel work for you is to have the right end condition to accommodate all processes your part will travel through.
5) Select Your Preferred Actuation Method
Tips: If you are planning on leaving your Xpandrel in the chuck or collet for part swapping consider a side actuation flange on the chucking end.
6) Add features
Tips: See the Modification Options page to get ideas that may help you reduce set ups and part flipping.
7) Material Considerations
Tips: Some designs are standardly aluminum while others are 4140-
