A barrel treatment apparatus, and a method of treating barrels comprises a treatment head H mounted on an arm 11, 12, moveable relative to support (S, Fig 2) passing into the barrel for removal of material from the inner surface of the barrel. Treatment head H is mounted in a pivotal connection allowing pivotal movement of head H on the arm. The apparatus has a treatment head feed mechanism configured to move the treatment head H laterally relative to the support and to control the orientation of the treatment head during the lateral movement. A multi-link pivot system controls the orientation for consistent presentation of head H against the barrel regardless of the degree of movement of a cutter (2, Fig 6). The treatment head H has lower and upper cutters 2l, 2u, configured to cut into the surface of the barrel in a cutting pattern which has at least two different depths of cut, i.e. ridges. Typically the ridges are parallel, and are spaced uniformly over the whole of the treated surface of the barrel. Other shown elements include drive shaft 5, bearing blocks 6, front plate 7, bracket 8, bottom plate 15, a pair of rear link arms 12, a pair of pistons 16 and motor 25. |
