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.
Circular-Slab Ready
• 2 000 mm maximum processing length, 1 000 mm width, 250 mm
depth—large enough for column segments and round countertops.
Built for 24/7 Production
• 51 kW total power drives both spindles and the auto water-re
cycling system (4 m³/h).
• 7 150 × 4 500 × 2 600 mm steel frame weighs ≥5 000 kg,
