FIELD: process engineering.
SUBSTANCE: invention relates to abrasive machining of workpieces. Workpiece is fixed on axially travelling centers. Workpieces and grinding wheel are rotated, the latter being fed periodically and radially. Workpiece is axially oscillated during the entire cycle of sparking out with amplitude selected subject to grinding wheel abrasive grit limits.
EFFECT: higher quality and efficiency.
