Abstract : A machine for precision grinding the outside and inside races of small ball bearings is described. The ring being machined is attached to a special mandrel installed in the opening of the spindle and is ground with respect to 3 parameters: track, diametral fit, and end. Machining is carried out by three grinding, high-frequency electrical spindles arranged in a separate block. For convenience and accuracy of grinding, each spindle has a separate transverse feed for boring. The spindles are moved hydraulically from one position to another. The machine can grind open outside and inside surfaces by the reciprocal motion of the table with the part. The given dimensions of the track are achieved by an adjustable micrometric stop. The end is ground with respect to the top which has a feed in the direction of the table's movement. The grinding wheels are dressed at the start of grinding by diamonds mounted near eac wheel. The grinder is completely hydraulic, all adjustment movements are automated. (Author)
