Three rollers hold the work piece at points approx 120 degrees apart and move such that they always inscribe concentric circles between them. This feature along with the interanl compensating system prevents the dislocation of work piece centre under changing clamping pressures. This results in high centering acuracy. With correct mounting, these styeady rests can be used for turning outside diameters, inside diameters, facing, drilling, grinding, induction hardening etc. Steady rests can be operated either hydraulically or pneumatically with mounts available for most popular machines
