AVANTECHNO 411

AVANTECHNO 411 is a professional mobile line boring and internal welding complex, designed for precise restoration of worn cylindrical bores and pin holes directly on site. The system combines boring, internal welding (build-up welding), facing, drilling, and thread cutting in one portable device.

The equipment mounts directly onto the component being repaired, allowing for on-site repairs without dismantling or transporting heavy assemblies. The coaxial centering system ensures high concentricity when restoring spaced bores.

Technical specifications:

- Boring range: Ø 22 – 400 mm (up to 1,000 mm with additional sets)
- Internal welding range: Ø 25 – 400 mm
- External welding range: Ø 20 – 250 mm
- Accuracy: up to 0.01 mm (H7 tolerance field)
- Feed rate: 0 – 0.5 mm/rev
- Maximum spindle speed: up to 450 rpm
- Continuous feed travel: 250 mm (extendable via bar length)
- Drive type: DC motor with permanent magnets
- Power supply: 220 V / 50 Hz
- Maximum power consumption: 3 kW
- Working temperature range: −30°C to +40°C
- Weight of electromechanical unit: approximately 42 kg

Functional capabilities:
