Bernardo MBS 600 DG double-mitre band saw – 2.2 kW, mitre cuts from -45° to +60°, Ø 410 mm
The MBS 400 DG (Ø 315 mm) covers 80% of standard metalworking needs. The remaining 20% consists of large profiles, thick bars and thick-walled tubes. The MBS 600 DG extends the capacity: Ø 410 mm (95 mm more), 540 × 300 mm flat material (vs 400 × 250 on the MBS 400 DG), 4290 mm blade (830 mm longer). For a metalworking shop producing 30–40% large components, duplicating the MBS 400 DG means buying two machines; a single MBS 600 DG reduces footprint, allows centralized setup and simplifies maintenance. Cutting speed of 45/90 m/min (vs 35/70 on the MBS 400 DG) speeds up cuts on mild steel: cycle time reduced by 15–20% on large volumes. Same 2.2 kW motor, hardened worm gear transmission ensures consistent efficiency. The hydraulic cylinder uses the same design and manages pressure on even irregular profiles (ovalized Ø 410 mm tube maintains uniform blade contact).

Frequently asked questions
What is the substantial difference between the MBS 400 DG and the MBS 600 DG, besides capacity? MBS 400 DG: Ø 315 mm, 3460 mm blade, 35/70 m/min speed, 2.2 kW motor, €7,259. MBS 600 DG: Ø 410 mm (+95 mm), 4290 mm blade (+830 mm), 45/90 m/min speed (+10 m/min), same 2.2 kW motor, €8,527. The main difference is extended capacity; the higher cutting speed on mild steel accelerates the cycle by 15–20%. For profiles <Ø 280 mm, the MBS 400 DG is more cost-effective; for 300–400 mm profiles, the MBS 600 DG is more flexible.
Why is the motor identical on the MBS 400 DG and MBS 600 DG if the capacity is larger? The hardened worm gear transmission + bronze gear ensure consistent efficiency. The longer blade (4290 vs 3460 mm) absorbs the additional load on large profiles without overloading the motor. The slightly different speed range (45/90 vs 35/70 m/min) keeps the thermal load consistent. The 2.2 kW motor is sufficient for both machines with the correct setup.
Can I make double -45° / +45° cuts on Ø 380 mm bars with the MBS 600 DG? Yes. The Ø 410 mm capacity allows Ø 380 mm with a 30 mm margin. Frame rotation from -45° to +45° takes 15–20 seconds per rotation. The adjustable hydraulic cylinder maintains uniform pressure on the large profile during rotation. ±0.5° angle tolerance is guaranteed with a control protractor after setup.
Is the 45/90 m/min speed fast compared with competitors? Yes, in the professional horizontal band saw segment it is competitive. 90 m/min on mild steel reduces cycle time by 15–20% vs the MBS 400 DG (70 m/min). 45 m/min on stainless steel is standard for blade protection (excessive heating above 45 m/min causes faster blade wear). Dual speed is flexible: manual adjustment for each batch.
What blade wear does the 4290 mm blade have over 100 consecutive bars? Estimated wear: 5–8 mm of blade length consumed over 100 mild steel bars at 90 m/min (average contact time 40 seconds per bar). The blade lasts 200–300 bars before replacement (at approx. 8 mm wear). Replacement blade cost: €180–250 + installation approx. €30–50 at a specialized workshop. Wear is low if the cooling system is properly maintained.
Does the hydraulic cylinder require frequent maintenance on large profiles? Standard annual maintenance is required (leak inspection, pressure gauge check, fluid change every 500–1000 hours). Large Ø 380–400 mm profiles slightly increase cylinder load compared with Ø 250 mm, but the robust design handles rated loads without problems if the pressure is correctly adjusted, typically <20 bar.
Is the MBS 600 DG suitable for foundry work, such as cutting raw post-casting bars? Yes. Raw foundry bars have irregular surfaces (oxide, slag); the adjustable hydraulic cylinder automatically adapts pressure to the profile. A speed of 35 m/min for cast iron protects the blade. There are some limitations on very friable cast iron, as fine metal crumbs can clog the band guide; consult Krollit for a specific setup for continuous cast iron.
