CNC Twin Blade Stone Arc Chamfering Machine for Granite & Marble 45° High Precision

If you’re still hand-chamfering columns or outsourcing round-slab edges, you’re burning money. Meet the upgraded CNC Twin Blade Stone Arc Chamfering Machine—the only twin-blade unit that combines 45° high-precision chamfering with a 2 000 mm circular-slab worktable. One machine, two processes, ten times faster than manual work.

What Makes This Model a Profit Engine?
True 45° Arc Chamfering
• Twin 250 mm CNC-controlled diamond blades cut mirror-finished 45° arcs on granite, marble, quartz and engineered stone.
• Servo feed (0–3 m/min) holds ±0.1 mm repeatability across every slab.

1. Circular-Slab Ready
   • 2 000 mm maximum processing length, 1 000 mm width, 250 mm depth—large enough for column segments and round countertops.
2. Built for 24/7 Production
   • 51 kW total power drives both spindles and the auto water-re
3. cycling system (4 m³/h).
   • 7 150 × 4 500 × 2 600 mm steel frame weighs ≥5 000 kg, eliminating vibration and micro-cracks.
4. Touch-Screen Simplicity
   • 15" PLC with pre-loaded chamfering programs; upload custom G-code via USB or Wi-Fi.
   • Laser edge detector aligns the blade to the slab in under 3 seconds.
5. Safety & Sustainability
   • Full CE-certified guarding, emergency-stop bars and integrated dust-extraction ports keep your shop OSHA-compliant.
   • Closed-loop water system cuts water costs by 70 %.
