rocess on Marine Gear Boxes Starting from 2, Wartsila designed gear boxes are manufactured and assembled at Flender GmbH in Germany. This allows us to combine the Wartsila knowledge of the market requirements and design capability with the strong Flender manufacturing background on gear boxes . Flender produces since 1, beside different types of industrial gearboxes, marine gearboxes for variety of applications and for customers worldwide. The manufacturing of complete marine gearboxes under the Flender brand hereby includes the design, the parts manufacturing and the assembly and testing. The whole process includes also the survey activities with the respective classification societies and procurement activities as well. For the logistics and manufacturing planning the mix between industrial and marine products means special challenge as series production needs different production set up compared to single parts production. special data matrix code stamped on each single part ensures traceability along the entire pr oduction line. The accompanying documentation allows supervising of each step of the machining process within the internal quality system. 4.1. The ma chining process for geared parts Production of the geared parts includes the soft machining, the hardening, th hard machining and the testing. Depending on the single part, either cut bar material or forged material is used. The product portfolio covers spur gear, helical gear pinions, bevel gears, shafts, hollow shafts, casted and welded housings and planet carr iers. Core technologies for geared parts are hobbing and form cutter milling for the soft machining and mainly grinding for the hard machining . 4.2. The Assembly and testing (FAT) The assembly follows the process written down in the internal work instructions. special, adapted, work instruction plan has been generated for the Wrtsil designed gearboxes. Within these instructi ons, each assembly step is
