ABSTRACT:
A chemical treating system includes a main row or line of equally spaced, equal length chemical treatment workstations for sequentially treating a workpiece such as the cylinder bore of an internal combustion engine cylinder. Additional longer chemical treatment workstations are located transversely of the main row of workstations so that larger workstations can be included in the chemical treatment system without increasing the total length of the main row of workstations. By locating the longer workstations transversely of the main row, equal distances between the main row of workstations can be maintained by using work transfer devices that move the workpieces longitudinally along the main row and transversely to the additional chemical treatment workstations in a sequential process. At the transversely located workstation, an airblower is provided to remove residual chemical treatment solution from the workpieces before they are returned to the main line of workstations. Where the workstation constitutes an electrolytic plating system for the workpiece surfaces, an electrically conductive conduit is included for conveying the plating solution so that the conduit may be utilized as an electrode during the plating operation.
