Reprochem has been producing for a considerable time abrasive stones for the finishing of
rotogravure cylinders, working on copper-plated, chromium-plated and nickel-plated surfaces, as
well as steel surfaces. Maximising on the experience of the “ACIGRAF” partner company which
manufactures amongst others diamonding and cylinder finishing machines, Reprochem is carrying
on a continuous research and development on the manufactured stones, keeping them updated
according to the newest technologies present on the market.
Considering the variety of finishing machines available on the market and taking into consideration
the various operating specifications of each machine, REPROCHEM produces several product
lines to optimally match with the specifications required by the customers.
The production range, therefore, envisages a series of differing hardness stones, which can be
best adapted to demanding work, different pressures, stones rotation speeds as well as to the
different passage speeds.
Considerable working pressures (50-70 kg.), high grinder-rotation speed (500-1400 revs/minute)
require harder and more compact stones in order to reach the best compromise between cut
standard and grinder wear.
Low work pressures (15-30 kg.) and reduced grinder-rotation speeds (50-300 revs/minute) require
softer and less compact stones to promote a better abrasive exchange and to maintain an optimal
cutting standard.
To work on reduced- circumference cylinders (400-600 mm) hard stones are better suited,
whereas to work on large-circumference cylinders (800-1500) a softer grinder material is more
suitable.
The stones are classified by grain, based on the required action, which could be rough-grinding,
intermediate finishing or finishing. The available grains are the following::
FOR COPPER POLISHING - SERIES N,T,H,K
120, 220, 240
