    After the success of the last V/O version of the LCV edge polisher, Marmo Meccanica is now proposing the same machine in the horizontal version, that is the LCH M-O/V.

    In alternative to the “V-GROOVING” system, the new “V/O-CUTTING” system allows to polish on a continuous mode minimum 45 mm wide and maximum 30 mm thick back splashes and produce narrow strips with the same dimensions ready to be glued on “L” bordered kitchen tops.

    These are the most important advantages of the “V/O-CUTTING” system:
    • the narrow strip only to be processed, not the entire slab
    • easier way to glue the two pieces together
    • almost invisible gluing line
    • possibility to create a stock of strips to be used when necessary.

    The LCH M-O/V is a simple and affordable machine that, beyond being equipped with the “V/O-CUTTING” system, maintains all the features of an edge polisher for up to 60 mm thick slabs, chamfers, calibration and drip-cut.

    The LCH 711 machine is the horizontal standard for the flat polishing machines in the industry. This machine is capable of polishing straight flat-squared 1 to 6 cm thick marble, granite, or engineered stone edges at over 120 lineal feet per hour. The working mode is on a continuous process basis; this means that all the pieces are loaded one after the other on the machine and move past a series of polishing motors so that they come out completely finished including a micro-bevel on the top and bottom of the material. The LCH produces material vertically, as they are usually handled, and it is this system that, besides avoided possible breaks of the material, reduces machine cluttering in your warehouse and also the area necessary for the operation. Moreover, the LCH does not require either foundations or treatment for water discharge. In fact, it can be simply placed on the ground and as it is completely streamlined, the discharged water can be easily directed to a point at some distance, by means of a hose connected to a special drain.

    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 polishing machines 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.

    The LCT 522 can perform multiple different edge details including full bullnose, half bullnose, pencil edge, bevels and flat polish. In addition to squared off or inclined edges, the LCT polishes multiple edge details and other convex shapes on slabs of marble, granite, or engineered stone. The machine is automatic and can work continuously; as long as the edges to be polished have the same thickness the pieces can be inserted one after another. Then they are carried by a conveyor belt through a group of automatic polishing motors which bear a series of abrasives, from the coarsest grain to the polisher. These abrasives are the same type as those on a normal edge polisher. In the “LCT,” the slabs of marble or granite are placed vertically, in the way they are normally handled. This system, in addition to avoiding possible breakages of the material, enables the machine to occupy less space and to reduce considerably the working area required.
