Enhancing Stone Processing Capability via CNC Router

Understanding the nuances of granite stone sink making

CNC systems are the cornerstone of stone fabrication. Advancement of production techniques using stone is primarily due to the use of computer numerically controlled routing machines. One such machine that is getting appreciation all over the world is the OMNI-CNC Stone Carving CNC Router. This Chinese CNC router is becoming popular primarily for the robust construction, precision and affordability.

The stone carving router from OMNI CNC is a 3-axis machine equipped with a powerful 4.5kW water cooled spindle capable of 24000 rpm (revolutions per minute). The feature of this CNC router is the machine table with coolant tray on wheels that allows moving the stone plate easily.


Anatomy of Stone Sinks Routing

CNC machines can slab cut stone particularly granite which is the hardest stone. . After cutting the stone with bridge saws the edges are routed on the CNC machine for application of epoxy. The edge work involves half bull nose edges and sink bottoms with a radius generally measuring three eights of an inch. This prevents flat bottom edge of the sink allowing the slope to the drain. CNC machining forms the perfect shape.

The other advantages of CNC stone routing is there is hardly any wastage of the granite or engineered stone. Remnants (remaining pieces from a larger slab) are utilized in countertop production which has made the use of CNC router an important cog in the kitchen production industry.


China produces some of the finest granites as stone quarrying is big business. The evolution of CNC stone routing in China has taken the industry into world class status as Chinese engineers such as OMNITECH began the process of innovation. In less than a decade the name of OMNI CNC is synonymous with CNC routing. One of the hallmarks of the OMNI CNC Stone Router is the machine frame which has extra thick steel tubes welded providing stability to the heavy stone workpieces. Along with the gantry that also has reinforcing ribs constructed out of tubular steel the firm beam assembly is a fine example of OMNI’s precision engineering and quality of workmanship.



To understand the beauty of granite stone sink routing a quick perusal of the You Tube video (link at https://www.youtube.com/watch?v=l_VRp2XTzMI.) shows the efficiency of the machining under a bed of water on the wheel configured table. The CNC machine’s chief feature is the accuracy particularly when making ogee edges. The quality of machining is exemplary – of course it does not matter if the CNC router has to bevel edges or straight edges or has to have a Dupont edge (a combination of ogee and half round). The OMNI CNC router is up to the task with its high spindle power and advanced control system.
