Chain Sprockets Manufacturing, on Vertical Machining Center GDV400PM1F4 Updated with Numerical Control NCT 2000M

The paper content comprise a few aspects regarding processing of chain sprockets on vertical processing center GDV400PM1F4 updated by changing the original equipment CNC-2S42-65 (1Я3.035.090) with NCT 2000M, which includes in short characteristics of two CNC, the old and the new one, the constructive elements of chain sprockets processed, enunciation of mains stages of manufacturing process adopted. The aim is to manufacture chain sprockets with classic tools, bypassing the need to design and build a sprocket hob in accordance with specified chain sprockets geometry, processing is performed on a machine which technological parameters have been improved.
