LCR 733

LCR is a special, line polisher for flat edges. Indeed, compared to other machines of the same kind, it can round and polish the two corners of a flat edge, besides chamfering them at 45° as all other machines can normally do. Flat edge at 90° with the rounding of the two corners is a kind of processing more and more required, especially in certain markets. So far just torus polishers, both with belt and stationary bench, have carried out this kind of processing. However those machines are rather slow as for this kind of profile (much slower compared than flat edge with chamfering or completely rounded edges). On the contrary LCR can perform the above profile as fast as polishingmachines for flat edge can do, and better than torus polishers, even on “difficult” materials, such as agglomerates. Besides the facing-polishing mandrels, LCR is also supplied with two units of three counter-oscillating mandrels each, that carry out travels of about 90° through an original and innovative mechanism planned by MM. That mechanism generates a natural, harmonious motion. It makes the masses of the two oscillating units balance out each other (and the reversing stresses compensate), thus allowing high oscillating frequencies. Alternatively, the two units of mandrels can be used in a static way (opposed at 45°), thus performing “classic” chamfering. LCR can be supplied with all the attachments available for other edge-polishing machines.
