The key to success Hi-tech for the perfect size GEDORE Tolerances achieved by GEDORE Your Advantage - Your PLUS in safety Precision dimensions ensure secure nut and bolt grip Long life of nut and bolt Complete transmission of available torque Top quality for better safety Open-ended spanners have been made since the dawn of technology. But the continued use of traditional tools does not mean that they are still manufactured by conventional production processes. Tried and tested production stages are subject to continuous development by our workforce. Where modern technology can improve the quality it is used. GEDORE grinds the spanner jaws to the exact rated size using a high-tech grinding machine. Perfect fit is the most important requirement for non-damaging and safe work. The production of a spanner From the tool blank to the final product. Quality comes with existence - Step by Step. (1) High-Quality Steel 31CrV3 Highly-efficient eccentric presses cut the blank for an open-ended spanner from high-quality flat steel. (3) Thermally Hardened Using a special thermal treatment achieves maximum hardness -and a guarantee of long service life. (2) Hot Forging Process In the pusher furnace the blank is heated to the exact pre-selected temperature and enters the forge while still red hot. The steel is given its form under the multiton blows of a drop hammer. Ip - "M l TV (4) Precisely Ground The jaws of the spanners are given their exact dimensions only after the hardening process. For this purpose a high-tech grinding robot has been developed especially for this operation. (5) Carefully Smoothed Any corners and edges still remaining are smoothed off by vibratory grinding until the heads and shaft are absolutely free of burrs. The heads are additionally ground. (6) Extensively Treated The extensive electroplating gives the spanners an effective surface protection and a perfect appearance. During this process an efficient recycling plant ensures that the environment will not be affected.
