AVANTECHNO MACHINES — DELIVERED WORLDWIDE Logistic chain is crucial for international trading. That’s why we …
AVANTECHNO presents an innovative technology of recovery of worn-out cylindrical joints, holes and fits surfaces of big-size assemblies and units of any heavy machinery.
The boring and welding complexes allow for operations of boring, welding and finish boring from a single clamping towards the part requiring recovery without disturbing the initial alignment. The technology includes the reconditioning of bores using a single machine tool (combining both boring and welding machine function) clamped directly on the defective assembly, without its dismounting or carrying out most of (dis)assembly works required for the conventional repair process (disengagement of hydraulic and pneumatic connections, untying of ropes, etc.). This is possible due to the clamping of the machine tool directly on the repaired assembly!
AVANTECHNO’s mobile repair technology allows for reconditioning of defective machinery in-situ, without dismounting and removal.
For the defective bore, the geometrical center position is determined, the mobile boring and welding complex is clamped onto the assembly under repair
Rough boring of the bore is performed till the ellipticity is removed
The bore is automatically welded with one or several metal layers
Finish boring to the required dimension is performed
The recondition repair is finished, the machinery can be operated further
down to 0.01 mm
from 3 hours
Reconditioned bore diameter:
from 22 to 1,000 mm
Reconditioned surface hardness: min. 25 HRC
Significant reduction of labor, material and financial costs for repair and reconditioning works:
