Finishing What follows interests the finishing operations of the lining applied on cylinders, to be performed after the lining application and vulcanization according to the instructions indicated in the specification of the used type of rubber compound. The finishing cycle usually performed is composed of: roughening to be performed on the lathe, taking away the major part of the applied extra thickness and leaving only a thin layer such to allow the finishing on the grinding machine. final machining, performed on a grinding machine, in order to reach the requested degree of surface finishing. Roughening on the lathe When the finishing cycle includes both the roughening on the lathe and the finishing on grinding machine, overthicknesses must be let after roughening, depending on the following processing and on the characteristics of the material Finishing on the grinding machine The finishing of the roll face is generally performed in two steps, one is the preparation and the other the real finishing.
