The first phase of Framag’s work for QSZ involved material positioning ‘for perfect cut’ with a frequency-controlled infeed and discharge conveyor. It also involved two opposing laser units to control the conveyors. The result of the first phase was a positioning accuracy of ±5mm. The sawing lines with forwarding devices for raw material are designed to be user-friendly and allow easy operation of both units by just one person. In the second phase the sawing unit was completed with a support grate, material

QualitätsSägeZentrum (QSZ), Germany, with an individual cutting machinery concept in order to process a variety of different material dimensions and qualities. QSZ is a quality sawing company for steel mills, forging companies, and pipe mills. Both of the company’s two factories operate fully automated band and circular sawing machines for cutting pipes, beam blanks or solid material of steel, stainless steel and non-ferrous metal. The company is able to process material up to a diameter of 530mm. GmbH

 Framag has supplied the KKS 1250 sawing machine to QSZ

feed unit (positioning accuracy of ±0.5mm) and scrap removal device. This allows a fully automated operation of the whole sawing process. The state-of-the-art circular sawing machine – branded type KKS 1250 billets – is used for sawing of solid material (round, square, rectangular). It is equipped with a centric main- and auxiliary clamping device and height adjustable table. The advantage is the hydraulic support of bent or curved material and protection of the saw blade against jam in the cut. This allows much higher durability of the sawing blades. On average more than 50m² saw blade tool life is achieved with this sawing machine. These outstanding values result from the technical combination of a sawing column including a Hydropol ® , extreme torsion-stiff and robust sawing gearbox. It also benefits from stable and vibration-free clamping devices. The combination of these three critical factors reduces the vibration caused by the sawing process. The KKS 1250 sawing machine allows cutting of round material with diameters from 180-420mm and square bar steels with edge length between 160mm and 400mm. Sawing blade diameters from 1,100mm to 1,350mm are possible, while a user-friendly Siemens PLC technics control system has

been implemented. Framag – Austria Fax : +43 7683 5040 86 Email : sales-st@framag.com Website : www.framag.com
