Definitions

Grinding and lapping machines for ball production are known from the common prior art, in which the grinding wheels and lapping wheels, hereinafter referred to as processing wheels for short, are arranged vertically or horizontally. At least one of the processing disks is not rotatable (stator disk) and at least one counter disk is rotatable (rotor disk). The balls are ground and lapped between these processing disks. Grinding and lapping machines of this type are designed for continuous ball passage. For this purpose, a circular ring sector is cut out in the stator disk and is divided into an inlet sector and an outlet sector by a radial guide and partition.
the auxiliary nozzles 20 can, however, possibly be dispensed with, the arrangement of the conveying fluid nozzles 18 in the rear boundary wall 12 is indispensable in order to exclude with certainty the formation of a dead volume in the ball conveying directed radially outward with respect to the machining disks.
