Nibblers - coil processing at Thyssen Krupp Nirosta
Before the stainless steel leaves the plant at Thyssen Krupp Nirosta, it is cut to the customer's specifications in the adjustment department. If material samples are taken, TRUMPF nibblers are used - in the briefest of times and with no risk of injury. Stainless steel is used today not only for sinks, beer kegs or chemically resistant material for lines and pipes. It is also highly prized in the automotive and construction industries. The material that arrives at the Thyssen Krupp Nirosta plant as a warm-rolled black band steel is transformed into high-quality RSH steel before being sent to the customer. Depending on the customer's needs, it may be plate or coil.
Cut to customer specifications
The workers in Adjustment are responsible for the final cut to spec. They place the steel bands in lengthwise or crosswise cutters and cut them to the customer's requirements. Andreas Bruster, adjustment expert at Thyssen Krupp Nirosta, explains, "Depending on what our customer manufactures, they need the stainless steel as a ring, in strips of various widths or in plate form. We cut the material to their specification."
Brief production stop
Interruptions in adjustment occur only when new coils need to be inserted, or when the material jams in the machine. The downtime is brief, however, because we cut the band with TRUMPF nibblers and the machine is back in production immediately. The nibblers are also used to take material samples, so we can prevent material confusion. Working with TRUMPF nibblers is pretty simple: they are placed against the sheet metal and then a light push in the right direction is all you need to start cutting. For instance, with the TruTool N 700, which can cut 5 mm stainless steel with ease. Due to the convenient guiding, operation is nearly vibration-free, and you can even work in hard-to-reach and tight places.
Low risk of injury thanks to good cut quality
Although the cut edge is not terribly important for Nirosta, a consistently good cut quality is still advantageous. That is because ragged sheet metal cuts are a potential source of injury. The workers also value TRUMPF's convenient service. Bruster explains, "We don't need replacement parts often for these tools, since the wear is so low. But when we do, they are here in no more than 48 hours."
