Coldwater’s automated tube straightening

Coldwater Machine Co., a Lincoln Electric company, released an automated, all-servo-controlled Tube and Bar Straightening system. The bar stock is rotated 360 degrees while sensors measure it at multiple data points along its length to create a profile. This data is sent to the PLC where it is compared to the straightness specification to determine where it needs to be corrected. A servo press, mounted to a servo-controlled rail, is positioned and then bends the bar repeatedly to bring it within tolerance.
