Case Study for Replacing the DAM 6X40 Lathe with Doosan LYNX 220 Lathe for Processing the Part "Body of Spark Plug"


Article Preview

This paper aims to provide the economic calculations that were made in order to make a comparison between the old technology used by a company, multi-spindle lathe DAM 6X40 and new technology that should be acquired, CNC lathe Doosan LYNX 220 for processing the part entitled "body of spark plug". The investment in the new technology is urgently needed given the age of the existing technology but the company wants to know in advance what are the costs and how long it would be able to recover the investment. In this regard were calculated the time rate for the operation, economy with direct wages, production capacity, amortization of the fixed assets, cost of the part at the enterprise-level and the return period of additional investment.
