Ten rolls tube straightening

THE Titan, produced by Comco (best known as Keins), is an all-in-one machine that includes the capability to uncoil, straighten, cut off, and de-burr tube with ODs up to 30mm. A tube transfer station is also included, as well as an optional pick and place operation. Processes can be performed with or without a mandrel, and the unit can be separated into individual processes creating an automatic or semi-automatic system. The advantages of such as system are the time savings and productivity increases that result from streamlining the process and reducing setup time for new production runs. Accuracy and cleanliness aremaintained as there are no chips, and the blades are fed by an AC servo as they rotate around the fixed tube, leaving no scratches. A built-in inner and outer de-burring unit produces smooth ends, while scrap and defective tubing are separately discarded. Comco – USA Email: comcousa@comco-groups.com Website: www.comco-groups.com
