• 2 HITECO 5.5 kW spindles — milling power for granite, quartz and marble — the CNC center for machining granite and quartz stone has two HITECO spindles of 5.5 kW each, a reference manufacturer for stone-machining spindles. Granite (Mohs hardness 6–7) and composite quartz (Mohs 7) are the hardest materials machined in the countertop industry — the HITECO spindles are dimensioned specifically for this class of materials, with adequate cooling and a construction that withstands the vibrations generated by machining hard stone over long periods of continuous production.

• 1,500×3,000×300 mm work area — covers large kitchen countertops — the CNC center for machining granite and quartz stone has a work table of 1,500 × 3,000 mm that covers granite and quartz slabs of standard dimensions (up to 3,000 × 1,400 mm) and oversized ones (3,200 × 1,600 mm with overhang). The 300 mm machining depth on the Z axis allows not only cutting and profiling, but also ornamental carving into stone blocks with thicknesses of up to 250–280 mm, relevant for manufacturers of architectural elements and sculpture.

• 8 vacuum suction cups on the phenolic table — firm clamping without damaging the surface — the CNC center for machining granite and quartz stone clamps the granite or quartz slab with 8 vacuum suction cups on a table made of hard phenolic board. The phenolic table does not damage the underside of the slab (protecting the finish), and the 8 suction cups provide a uniform holding force over the entire surface of the slab, critical for machining stability at high feed rates on hard stone. The 2.2 kW double-vortex vacuum system provides the suction force required even on the partially porous surfaces of natural granite.

• Edging + engraving switching with a single button — maximum productivity on countertops with decorative elements — the CNC center for machining granite and quartz stone allows switching between the edge profile (edging) and decorative engraving without reconfiguration, with a single push of a button. On premium kitchen countertops that combine a profiled edge with decorative engravings or personalized inscriptions, this fast switching eliminates the pauses between operations and increases productivity on orders with multiple machining operations on the same countertop.

• Ncstudio 95A-3S controller — industry standard for stone CNC — the CNC center for machining granite and quartz stone uses the Ncstudio 95A-3S controller, the control system used as a standard in stone CNC centers worldwide. Ncstudio offers an interface familiar to operators experienced in the stone industry, accepts DXF files and other standard CAD formats, and has specific functions for managing water cooling and feed parameters on different types of stone.

• SHIMPO gearbox + Best inverter — precision kinematics for fine profiling — the CNC center for machining granite and quartz stone combines the SHIMPO gearbox (a reliability standard in industrial transmissions) with the Best 5.5 kW inverter for precise control of the HITECO spindle speed. Speed precision is the critical parameter for surface quality when profiling granite and quartz edges — speed variation produces non-uniform surfaces on mirror-finished edge profiles.

• Automatic lubrication + integrated water cooling — continuous production without overheating — the CNC center for machining granite and quartz stone has an automatic lubrication system for the guideways and racks and a 3 kW water circulation pump for cooling the diamond blades and the spindles during machining. Water cooling is mandatory when machining granite and quartz — without cooling, the diamond blade overheats and deteriorates rapidly, and the stone surface can crack thermally. The integrated cooling system of the CNC center for machining granite and quartz stone eliminates the need for an external cooling system.

• Igus cables + configuration on request — reliability and adaptability — the CNC center for machining granite and quartz stone uses Igus motion cables for long-term reliability in the wet and abrasive environment specific to stone machining. Configuration on request allows the equipment to be adapted to the specific types of stone, edge profiles and production volumes of each countertop studio or marble works. 60-month UZINEX warranty, spare parts in stock in Iași, national technical support within 24–48 hours.

Applications — the CNC center for machining granite and quartz stone

Kitchen and bathroom countertop studios working with natural granite and composite quartz stone are the primary user of the CNC center for machining granite and quartz stone. A granite kitchen countertop requires cutting the slab to the kitchen dimensions, milling the cut-out for the sink, profiling the edge (straight, ogee, bullnose, bevel or custom profile) and finishing the cut surface — all performed by the CNC center for machining granite and quartz stone in a continuous cycle, with precision and perfect repeatability across the entire order series.

Marble works and manufacturers of architectural decorative elements from natural stone — sculpted balustrades, decorative panels, sills, window frames, ornamental columns — use the CNC center for machining granite and quartz stone for 3D carving and engraving in calcite, marble, travertine and granite. The 300 mm machining depth on the Z axis allows stone blocks to be approached for decorative elements with volume, impossible to achieve on CNC centers with reduced Z travel.

Manufacturers of pavers, slabs and decorative cladding from natural stone use the CNC center for machining granite and quartz stone for personalized engraving — textures, reliefs, inscriptions and geometric patterns engraved on the surface of granite and marble slabs. This application is growing on the Romanian market, alongside the increased demand for personalization of exterior and interior natural-stone landscaping elements.
