As a rule, brush deburring machines are not used on their own, but often in combination with pipe cutting machines that cut lengths of pipe from a metal pipe to a high degree. The cut-to-length section will then be further discussed. The further treatment can take place in various successive process steps, in particular pipe ends can be chamfered and / or washed and / or just deburred. The brush deburring machine frees the ends and cut surfaces of the metal tubes during their transport by means of transport discs from sharp edges and pipe chips left over in the cutting process. Such Bürstentgratemaschine is from the US 3,045,268 known.
