Abstract (en)

[origin: EP0411345A2] The invention relates to a feeding and dosing attachment for the lapping mixture in finishing machines for lapping, grinding or polishing, having a vertical-axis arrangement of two working wheels, the intention being for the feeding and dosing of the lapping mixture to be controllable as a function of the specification of the part to be machined in each case and of the selected cutting conditions. Furthermore, by means of a wiper device rotating relative to the top working wheel, the lapping mixture can be distributed in one or more annular channels on the back of the top working wheel and can be fed to the operating space via bores. <IMAGE>
