83,000 operating hours and now as good as new

For Maschinenfabrik Niehoff, top quality, durability and value retention have always been the priorities when it designs and produces its machines and lines. Niehoff machinery which has been in operation for decades is worth reconditioning and being brought up to the latest technical standards. With special measures, Niehoff upgrading specialists are even able to increase the machines’ original level of productivity. In this way, Niehoff Original+ After Sales has been optimising machines and lines for decades. One example is the full reconditioning of a multiwire drawing line which was supplied by Niehoff in 1996. The line, an MMH 101 multiwire drawing machine with integrated RM 140 contin- uous annealer and an S 631 spooler designed for the simultaneous drawing of 24 copper wires, already has 83,000 hours of operation behind it and is used after reconditioning in one of the user’s non-European plants. The first measure taken before every machine is reconditioned is an inspection of the line by a Niehoff engineer on-site. After this the Niehoff specialists discuss with the user all the reconditioning work which is necessary, and draw up a quotation for the work. In the present case, the drawing line was transported to Niehoff’s headquarters in Schwabach, Germany, completely dismantled, cleaned and stripped of its paint. After each of the assemblies had been checked, the machines were repainted. The bearings and sealing flanges were completely replaced. In addition, the annealer was completely refurbished and the line’s electrical

The Niehoff specialists who are involved in a reconditioning project are fully familiar with all aspects of the underlying machine technology. Moreover, they have access to well- maintained documentation and machine data. Most of the spare parts required for each reconditioning job are produced in-house on cutting-edge machining centres to OEM quality. Where third-party components are brought in, Niehoff makes sure that they all meet the high Niehoff quality standards. Maschinenfabrik Niehoff GmbH & Co KG – Germany Website : www.niehoff.de

components were adapted to the power network of the country in which it is to be used in future. Given the hot climate where the line is to be used, an additional cooling system was installed in the control cabinet. Following assembly, a test run and a pre-shipment inspection by the user, the line was delivered to its new point of use in North America, installed and put into operation by Niehoff engineers. Niehoff specialists are best qualified to recondition the machines and lines manufactured at Niehoff with maximum expertise and put them back into tip-top condition.
