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 %.
Real Results from Real Shops
• 68 % labor-cost reduction after switching from manual chamfering.
• Rejection rate <0.5 % thanks to twin-blade stability.
• ROI in 8–10 months for high-volume granite countertop plants.
