The manufacturing sector in Germany comprises almost 200,000 industrial companies, of which around 98 % are small and medium-sized enterprises (SMEs). Approximately 750,000 CNC-controlled machine tools are operated in the industrial companies of the EU27. Associated with these machine tools is a Europe-wide energy consumption of an estimated 200 to 300 TWh per year, which corresponds to about 6.3% of the total energy consumption of the industrial sector (EU27). Cutting fluid systems are in use in nearly 75% of these industrial companies. The numerous variations and components of the cutting fluid systems, result, by the process-conditioned necessary operation, in a high energy requirement portion. This energy share amounts to approx. 30-35% in a production system (tendency increasing).
