Kieselstein International also offers comprehensive R+D services. In-house draw-peeling machine tests are carried out in cooperation with customers in order to find the optimum set-up for their machines. Using a video-measuring method developed by Kieselstein, the draw-peeling process can be examined and evaluated thoroughly. Kieselstein International GmbH – Germany Fax : +49 371 9104105 Email : info@kieselstein-group.com Website : www.kieselstein-gmbh.com Lubrication is one of the crucial factors for the quality of drawn wire. An interrupted lubrification in the steel wire drawing process can cause increase of surface tension in the wire, strong pressures inside the die, rapid die wear, breakage of the drawing nib and consequent non-programmed interruptions in the wire drawing process. In order to avoid such problems, Koner SpA, Italy, has created a new concept line of drawing dies. The K.340 and K.370 pressure ❍ Koner SpA – Italy Booth G12

drawing dies (patented worldwide) are designed to greatly improve lubrication in dry drawing of steel wire. For wet drawing the K.320 tool has been created, which allows optimum wet drawing process characteristics. Operating advantages of the new dies include production at maximum drawing speeds, less machine down- time for die replacement, better and more homogeneous wire quality, wire drawing under optimum quality control, increased nib life, and application of the requested quantity of lubricant coating to the wire. The overall dimensions of the new dies are the same as for traditional dies. Koner can rapidly supply its new dies to any part of the world m

several blades during other processing methods. After the draw-peeling process, the wire surface neither needs to be hardened, nor requires any polishing or grinding. In addition to valve spring wire and steel wire, the process is suitable for aluminium, copper, nickel alloy and different special materials. A milestone in the development of the procedure and the respective machine technology is the modular type series of high-speed draw-peeling machines. The new modular concept allows a gentle processing, improving the quality of the finished wire, while improving productivity by increasing the draw-peeling speed.
