Abstract (en)
[origin: EP0359304A2] Provided before a method consisting of precision grinding with subsequent finish grinding is a grinding phase in which the grinding belt (21) is movably pressed under predetermined pressure against the outer surface (45') of the preheated cylinder (45) to be machined within a certain clearance X or X', adjustable by means of an adjusting device (30), between a copying template (10) and a contact roller (23) in such a way that, in this preliminary grinding phase, stock is uniformly removed from the cylinder surface (45') irrespective of its geometry. After a surface layer of the cylinder (45) formed from various particles has been ground down, the proportional pressures applied to the belt-grinding unit (1) are changed in such a way that, in the now following first grinding phase, the actual precision grinding, a fixed connection is set between the copying template (10) and the contact roller (30). A uniform distribution of temperature and thus also a uniform expansion of the cylinder surface (45'), which is of importance especially in the radial direction, are thereby ensured, as a result of which a more accurate cylinder geometry is achieved. <IMAGE>
