新镗床 AVANTECHNO 411

The AVANTECHNO 411 is a professional mobile line boring and internal welding complex designed for precision restoration of worn cylindrical bores and pivot points directly on site. The system integrates boring, internal surfacing (welding), facing, drilling and thread cutting in one portable unit.
The equipment is mounted directly onto the work piece, allowing on-site repair without dismantling or transporting large assemblies. The coaxial alignment system ensures high concentricity when restoring spaced bores.
