Model 3RR 
3 Roller

     Roller rests are used in screw machines, turret lathes and CNC lathes to provide support for a workpiece undergoing a cross slide operation. Hardened, precision free-turning rollers eliminate galling and marring of the workpiece. With a third roller, you get more stability and less chatter. Rollers are individually adjustable to compensate for workpiece misalignment and wear. A third roller rest gives more stability to the work-piece when cutting long pieces.
