United processes: sawing, deburring and checking

German steel and metal distributor, Klöckner & Co, is responsible for the first stage of metal preparation for automotive manufacturers and their component suppliers. The plant produces components of any shape and dimension, including flat, square and round material, tubes, solid bars and sections of different materials. Between 40-50t of processed material leaves the preparation centre daily. A completely modular sawing centre from machine manufacturer RSA, Germany,

was designed to ensure smooth running of Klöckner’s manufacturing flow. For this purpose, the Rasacut sawing centre unites several working steps: sawing, deburring, checking, and commissioning. To complement the Rasacut, the company also supplied the Rasacheck measuring system to check the length of tubular workpieces, and supervise the process. The 100 per cent measuring of the RSA system avoids the delivery of any defective parts, instead of relying on calculations of probability. The length measuring system, which is integrated into the sawing centre, automatically ejects every faulty piece on fi The Rasacut sawing centre consists of inde- pendent modules which can be freely combined and extended

the spot. If a freely definable maximum quantity of defective workpieces is produced in sequence, the whole sawing centre shuts down in order to avoid rejections. The measuring module requires no setting up or adjustment work, and can be linked to any other brand of machine or integrated into any production line. The measuring data can be transmitted to any QA software, or documented and analysed by RSA software. Documentation of measuring data and statistical computations are available on CD, hardcopy, or can be sent to a third party via remote data transmission. › The Rasacheck module measures up to 5,000 parts per hour, and automatically ejects faulty parts
