AVANTECHNO 411

AVANTECHNO 411 is a professional mobile line boring and internal build-up welding unit, designed for the precise restoration of worn cylindrical bores and pivot points directly on-site. The system integrates line boring, internal welding (build-up), facing, drilling, and threading in a single portable device.

The equipment mounts directly onto the workpiece, allowing in-situ repair without disassembly or transportation of heavy components. The coaxial centering system ensures high concentricity when restoring spaced-out bores.

Technical specifications:

- Boring diameter range: Ø 22 – 400 mm (up to 1,000 mm with additional kits)
- Internal build-up welding range: Ø 25 – 400 mm
- External build-up welding range: Ø 20 – 250 mm
- Accuracy: up to 0.01 mm (H7 tolerance field)
- Feed rate: 0 – 0.5 mm/rev
- Maximum boring bar 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
- Operating temperature range: −30°C to +40°C
- Electromechanical block weight: approximately 42 kg

Functional capabilities:

- Single-pass coaxial restoration of multiple aligned bores
- Internal welding with continuous spiral build-up technology
- Facing of flanges and mounting surfaces
- Restoration of bearing seats and circlip grooves
- Restoration of blind holes
- Quick changeover between boring bar and welding shaft without the need for re-centering
