The upgrading procedure

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 possible, 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 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 in future, 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.
