The R-O® principle of relieving is based on the actuation
of the basic R-O® fixture as described below.
Its design which has proved so successful, eliminates
rocking action and affords positive control of relief,
offers improved grinding control through its master
drive and stepless speed control.
The Power unit is a D.C.,110 volt gear reduction motor
with stepless speed control. Gear reduction is 40:1 giving
44 inch pounds of torque. Speeds from 0 TO 80 RPM
at the dial, through a timing belt drive.
