    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.

    ADVANTAGES OF THE LCR 733:
    • Fully automatic straight edge polishing
    • Production speeds of 80 to 120 l/f per hour

    LTN is a polishing machine for round edges up to 8 cm and flat edges up to 10 cm thickness, born by the need to create an essential, solid and compact machine at an affordable price that is equipped with a high level of automation. The LTN maintains the shaping principle by means of a single cup-shaped diamond wheel for all profiles and thicknesses. The oscillation system is driven by two motors connected and ruled by a single inverter, which allows mechanical simplification, reduced maintenance, high performance and good reliability. The structure is monocoque and self-supporting (not coated and tubular framed). Waste water is piped in a unique collector (it neither falls directly to the ground nor on the bearing base of the machine). All protections are made of strong and safe stainless steel.

    a wide range of supplementary automations and accessories available
    Dimensions from 4000 x 1900 mm
    Power: from 26 Kw

    The LTN 621 is composed of:

The mandrel can be adjusted both laterally and longitudinally with respect to its supporting shaft; moreover, it can be rotated from 0° to 90°, and can also be used to carry out slotting for the drip stone. For Ø 250 mm tools.
    • 2 OPPOSING MANDRELS INCLINED AT 45° to cut chamfers and/or bevels of various dimensions. Whenever you need to carry out rounded profile edges, these mandrels, thanks to the use of specific diamond cone trunk grinding wheels greatly help the shaping made by the oscillating mandrels to the desired edge shape. For Ø 130 mm wheels.
    • 6 OSCILLATING MANDRELS of which the first two are ready to be equipped with cup-shaped diamond grinding wheels in order to carry out the shaping of the rounded profiles or the grinding of the flat, squared off or inclined profiles. The other four mandrels are equipped with polishing and smoothing abrasive grinding wheels. If necessary all the 6 mandrels can be equipped with abrasive grinding wheels. Other models derived from the standard LTN 621, by adding extra functional units, can be built on request. For Ø 130 mm wheels.
    Main features:
    • The control panel is easily accessible on its articulated arm.
    • The oscillating mandrels are unified, tested on thousands of machines, and protected by a mazelike mechanical system (without bellows). Each mandrel has a hydraulic motor and makes distinct revolutions.
    • The mandrel-holding beam is pressurized and works by a lever-and-rod oscillation system (it requires no maintenance and has been highly tested – 1987 MM original patent) and micro-oscillation for flat parts.
    • The oscillation system is driven by two motors connected and ruled by a single inverter, which allows mechanical simplification, reduced maintenance, high performance, and good reliability.
    • The color, tactile programmer (touchscreen) allows to set the machine quickly and intuitively by choosing various default profiles.
    • The positioning of the first self-shaping mandrel is automatic.
