Fig. 4—All major mass-finishing-equip- ment suppliers maintain test labs, such as Rosler Metal Finishing USA’s lab in Battle Creek, MI (right), where they can run processing trials with a customer’s work- pieces to develop the optimum finishing process and choose the right combina- tions of equipment and consumables.
typically must be processed with less- abrasive media, while hard-to-machine metals such as titanium require a more aggressive treatment.
Processing Trials Yield Optimal Finishing System
Of course, selecting the right machine, media and compound can be a bit intimidating. Not only must shops choose among a variety of machine types and sizes, they must also pick the right media from hun- dreds of types, shapes and sizes. And, they must select the right compound, and ensure that the process water is not too hard or too soft.
That’s why the choice of machine, media and compound should be left to the experts. All major mass-finishing- equipment suppliers maintain test labs where they can run processing trials with a customer’s workpieces to develop the optimum finishing process (Fig. 4), and choose the right equipment and consumables.
Considering the fact that mass fin- ishing is highly empirical technology offering hundreds of equipment, media and compound combinations, it is not surprising that more than 95 percent of all equipment sales are preceded by pro- cessing trials at the equipment suppliers.
Once a mass-finishing process has been established with the selection of machine, media and compound, the system must be constantly monitored and, of course, properly maintained. By following a few simple quality-control rules (see Table 2), the process will remain stable, producing the desired finishing results. If needed, Table 3 offers helpful troubleshooting tips.
