SOUTHFIELD, Mich., January 11, 2005 - Marmo Meccanica USA announces availability of the LCT 522 CAI, a highly effective edge polishing machine featuring a user friendly operating system that ensures a high rate of production at a low cost per lineal foot. Its small footprint, combined with its high reliability and low cost, make it ideal for granite shops in North America who want high quality processing of marble and granite.

 

The LCT 522 produces 30-60 lineal feet of 3 cm bullnose per hour with no human intervention. That's because edge processing on the LCT 522 CAI machine is continuous. Different pieces of identical thickness can be inserted sequentially without the need to change forming or polishing heads.

 

Granite and marble slabs are vertically inserted into the LCT 522 CAI. Handling slabs vertically not only reduces the possibility of material breakage, it also considerably reduces the floor space and work area requirements.

 

Slabs are moved on a conveyor belt through the machine on a group of automatic mandrels that bear a series of abrasives, from the coarsest grain to the polisher. The finish on the edges produced is free from lines, facets or other imperfections due to the unique random oscillation of the polishing arm. Upon completion, slabs are perfectly formed and polished.

 

Many types of edge treatments can be processed on the LCT 522. In addition to squared off or inclined edges, it polishes toroidal edges, rounded and other convex shapes on slabs of marble or granite.

 

The LCT is extremely user-friendly. The operator needs only to input the thickness of the material as well as the appropriate angles for the type of edge being processed. Typically, this is 7 to 173 degrees for full bull nose and 7 to 90 degrees for a one-half bull nose.

 

Forming wheels are used when processing shapes such as a bull nose or one-half bull nose. Pre-forming wheels are quickly and easily mounted using tool adjustments provided for exact positioning.

 

The machine is equipped with two opposing bevellers. The bevellers are used to produce bevels of various sizes, particularly for removal of excess stock when processing bull nose and a one-half bull nose.

 

The LCT 522 is equipped with a gauging spindle to gage the materials for thickness to ensure even edges. The spindle is adjustable from 0 to 90 degrees and may be mounted with other types of diamond tools to achieve large bevels and other cuts.

 

A CAI computer controls the work cycles of the polisher with high precision and carries out diagnostic functions, maintenance programs and statistics.

 

Machine dimensions are: 3700 mm (12.14 ft) long X 1200 mm (3.94 ft) wide X 1500 mm (4.92 ft) high. Its weight is 2300 kg (5071 lbs).
