The wheel-axles of a track maintenance train had to be devarnished. Because of time pressure it was not possible to dismount the axles. For devarnishing a CLEMCO Dust-Free Blast Machine HSP-20 and a CLEMCO Dust-Free Blast machine FS-200P were used. As blasting abrasive Fused Alumina was chosen. The technical equipment was provided by us and we instructed the personnel. The work was completed succesfully. Unfornutately no photos were taken.
