Transfer Machines Achieve High Levels of Precision

Winema is developing customized transfer machines for the production of long runs, families of parts and component variants, all in batch sizes. The PTC enables the user to machine the external contour of the workpiece without positioning errors, according to the company. It is integrated in the machine as a disconnected turning cell, and it is free of the drive and machining factors that affect the other stations.

With a closed, internal design, the cell can transfer the workpiece into an independent coordinate system where it can conduct a turning process in isolation. The vibration-damped cast design disconnects the turning process from the machining factors that affect the other stations. According to the company, by turning between tips, concentricity requirements that used to be critical can be manufactured without any problem down the entire length of the workpiece.

If the workpiece is held in a collet chuck, tight positional tolerances can also be maintained between external and internal contours. Two turning tools with Capto interface are integrated in every turning cell.
