CMS Brembana Xtreme

Standard stone edge profiles achievable on the Brembana Xtreme 5-axis head: (1) Eased edge (1/8 top bevel) - most common; (2) Pencil round (full round top edge); (3) Bullnose (full round top and bottom); (4) Ogee (S-curve profile) - requires 5-axis to undercut; (5) Waterfall edge (full thickness drop with square corners); (6) Dupont edge (round with flat return); (7) Laminated edges (two layers of stone bonded for apparent thickness); (8) Cove and bevel combinations; (9) Custom profiles programmed from DXF profile geometry. 5-axis capability is essential for full-radius bullnose and undercut profiles (ogee, dupont) - on 3-axis machines, these profiles require multiple setups or manual grinding to complete.

Diamond tooling for the Brembana Xtreme is material-specific: (1) Granite tooling: segment-type diamond grinding wheels for rough shaping (50-100 grit), finer wheels for profiling (100-200 grit), polish pads (50mm) for final polish. Granite's extreme hardness requires high-bond-strength diamond; (2) Marble/limestone: softer diamond bond (marble is much softer than granite); higher diamond grit concentration; (3) Engineered stone (quartz composite): similar to granite in hardness; specific composite tooling for the resin-bonded quartz matrix; (4) Ceramic tile: dedicated sintered diamond wheels for porcelain cutting speed. Water during cutting is mandatory for diamond tooling - dry cutting destroys diamond tools within minutes from thermal damage. Tool life: granite profile bits typically 200-500 linear meters per bit depending on profile complexity.

3-axis stone machines process edges with the tool perpendicular to the edge face - they can produce square edges, simple chamfers, and partial round profiles. 5-axis machines can angle the tool head to machine undercuts and full-contour profiles from any approach direction. Practical advantages: (1) Ogee profiles (which have an S-curve requiring an undercut on the lower portion) are impossible on 3-axis - 5-axis machines them in a single pass; (2) Full bullnose on thin stone (20 mm) where the radius equals the material half-thickness requires continuous 5-axis rotation to maintain contact; (3) Laminated edge buildup with flush seam matching uses 5-axis approach for seamless joint cutting; (4) Complex vessel sink cutout geometries with angled sides use 5-axis for precise geometry. For shops producing premium countertops with complex profiles, 5-axis capability commands premium pricing and differentiates from competitors using 3-axis machines.

For a typical L-shaped kitchen countertop (2,400 mm x 600 mm + 1,200 mm x 600 mm return, bullnose edge, single undermount sink cutout): total processing time approximately 20-35 minutes per countertop section including tool changes and repositioning. Output: 2-3 complete L-shaped sets per hour, 15-24 sets per shift. For simpler straight runs with eased edge only (no sink): 8-12 minutes per countertop = 5-7 per hour. For high complexity (multiple profiles, multiple sinks, cooktop cutout): 40-60 minutes per countertop = 1-1.5 per hour. Most countertop shops target 3-5 complete kitchen package sets per shift as their production goal. The Brembana Xtreme handles the full process in one machine - sink cutout, edge profile, and drilling for faucet holes.

Stone CNC machining water requirements: (1) Water supply: 20-40 liters/minute continuous flow to the machining head; municipal water or recirculated filtered water. (2) Settling tank: 2,000-5,000 liter tank for stone slurry settling - slurry settles as calcium carbonate (marble) or silica/quartz particles (granite) at the bottom of the tank. (3) Recirculation pump: returns settled clear water to the machine. (4) Slurry disposal: settled sludge is dried and disposed of as non-hazardous solid waste (verify local regulations). (5) Floor drains: sealed concrete floor with drains around machine perimeter rated for continuous water flow. (6) Silica dust control: in addition to water, some regions require continuous air filtration monitoring for crystalline silica (OSHA silica regulation compliance). The facility infrastructure for a stone CNC is a significant additional cost beyond the machine itself.
