Abstract: An improved gauge assembly is utilized to measure the size of a workpiece during a grinding operation. The gauge assembly includes upper and lower gauge members which are movable under the influence of a pair of fluid motors. When the gauge assembly is in an open condition, the upper gauge member is held in a raised position by a relatively high fluid pressure supplied to the motor associated with the upper gauge member. At the same time a relatively low fluid pressure is supplied to the fluid motor associated with the lower gauge member so that it remains in a lowered position. When the gauge assembly is to be utilized to measure a workpiece, the fluid pressure in the motor for the upper gauge member is decreased to enable the upper gauge member to move downwardly into engagement with the workpiece. At the same time, the fluid pressure in the motor for the lower gauge member is increased to raise the lower gauge member upwardly into engagement with the workpiece.
