The paper presents a machining of near-net shape (NNS) pinions with forged chamfer in automotive industry and compares it with an older procedure of turning pinions without forged chamfer as well as production of pinions in a classic mechanical way from steel bars. It contains a description, which focuses on a technological procedure, utilization of different types of tools, and machine tools. The last part of the paper deals with an economic analysis considering sub-assembly of car starter motors production, their treatment and pinion production in a classic mechanical way from steel bars and with NNS process. The calculations are presented for different batch sizes from prototype to mass production.
