AbstractThis paper describes recent research regarding: 1) the influence of the water flow and the pressure
in order to attain the best polishing in portuguese limestones; 2) the experimental validation of a
polishing simulator under development at Instituto Superior Tecnico (Lisbon). The research work
was carried out using slabs of calcareous stone Moleanos, from Portugal, and the polishing
sequence employed commercial Frankfurt-type abrasive tools applied for the last 3 stages of the
process in order to attain maximum surface gloss. The study was conducted with a single-head
laboratory-type polishing machine, where all test conditions are adequately monitored and
controlled. The polishing head contains 6 Frankfurt abrasives of the same grit size (320#, 400# and
5Extra). The surface quality was assessed, after each polishing stage, by means of a glossmeter.
In the end, it was possible to identify the optimum working parameters for each polishing stage.
The results obtained also show that indeed a correlation exists between experimental values of
gloss and the abrasion data given by the simulator.
