3Ruler system, the first mechanical reference system for WEDM
System 3R’s ruler system – 3Ruler – was developed for machining medium-size and large workpieces in machines with a parallel or U-shaped machine table, as well as in machines with a frame table. The rulers, which have built-in height adjustment, are used singly or in pairs. A comprehensive range of accessories gives the rulers an unsurpassed range of applications. With the aid of 3Ruler, rectangular or round workpieces, large or small, lightweight or heavy, are located on the machine zero line, without risk of collision. System 3R’s WEDM accessories upgrade the versatility and productivity of your machine by practically eliminating setup times.
