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 is supplied as a kit with a grind module, drive module, and controller. The drive and grind modules mount right to the flat base frame on either end of a bar. The conditioner also works for tension and compression striker bars.
