Flawless tubes in record time – New quality standards in production pro-
cesses
QASS is a manufacturing company of meas- uring systems for production processes. The initial success from the discovery of structure-borne sound as a relevant source of process information in straightening processes quickly developed into more use cases and different measuring approaches – now offering a wide portfolio of hard- and software for various production processes.
Improving tube drawing production effi- ciency and product quality
QASS offers a new revolutionary way of in-line process monitoring for tube draw- ing processes helping manufacturers
to increase tube quality and production efficiency. Challenges that manufacturers are commonly facing, are chatter marks on the outer and inner surface of the tubes and the resulting scrap. Machine opera- tors have to manually control the drawing speed to try to avoid those problems. This manual operation often leads to a relatively slow production to ensure quality stand- ards.
Chatter free drawing - How it works
The robust QASS structure-borne sound microphones are bolted near to the draw- ing tools and sense all the forming and friction emissions in real time. QASS spec- tral analysis allows the suppression of all normal machine operating noise so that the earliest signs of chatter are detected. Long before the operator notices chatter- ing, the QASS measuring device reacts and calculates an adjusted drawing speed. If the drawing process calms down, the speed is immediately increased again. The braking and acceleration values are adapted to the machine and pipe type.
Using this method, the drawing speed can be kept at a high rate for longer with only short periods of slowing down. With a sub- sequent increase in production volume, the system proves to be beneficial in more than one way.
Maximize drawing speeds for any tube
The latest QASS software is dedicated to increase the maximum drawing speeds.
