CNC stoneworking systems are being used for a broad range of production demands, including unique custom pieces as well as large orders of identical pieces, such as hotel countertops. They are also used for jobs such as statues and memorials, where attention to detail is very important. No matter what the end product may be, the machines continue to advance stone design.
Newer CNC systems include the Omag Profiler, a routing and engraving machine, designed for marble, granite, limestone and glass. It is capable of working in 3 or 4 axes simultaneously, allowing operations such as carving, engraving, contouring and drilling. All axes movements are powered by brushless AC servo motors, which drive precision ball screws. Linear bearing and guides - both protected by PVC bellows - act as the machine ways. Moving components are lubricated by a centralized system, which is programmable through the computer. A frequency converter system controls the spindle, maximizing horsepower and torque. The spindle is ISO 50 tool change version. A saw blade up to 500 mm in diameter can be used with the spindle and rotated at a full 360 degrees to produce angular cuts. Omag machines are distributed in the U.S. by Bergman-Blair Machine Corp of Oyster Bay, NY.
