AVANTECHNO 411

AVANTECHNO 411 is a professional mobile line boring and internal welding complex, designed for precision repair of worn cylindrical bores and pivot points directly on site. The system combines boring, internal welding (build-up), facing, drilling, and tapping in a single portable unit.

The equipment is mounted directly onto the workpiece, allowing on-site repairs without disassembly or transporting heavy assemblies. The coaxial centering system ensures high concentricity when refurbishing distant holes.

- External welding range: Ø 20 – 250 mm
- Accuracy: up to 0.01 mm (H7 tolerance field)
- Feed rate: 0 – 0.5 mm/rev
- Maximum bar rotation 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
