REL’s bar end conditioner allows every user the option to regrind their SHPB bars ends as often as needed without ever removing them from the system.

In many cases this eliminates the need for bar insert protectors when testing hard materials. The bar end conditioner kit includes a grind module, a drive module, and a controller. The drive and grind elements mount on REL's precision aligned base frame on either end of a bar. The conditioner works for all incident, transmission, and striker bars.
