New production methods in cutting and degreasing of copper and cooper alloys

Objective



Machining of copper and copper alloys is negatively effected by metal solubilization in the cutting emulsions. The consequences are spotted metal surfaces and malfunctions in the subsequent degreasing. Furthermore a source for metal pollution hazards is founded. The turnover of heavy metal contaminated emulsions is estimated to 5 000 m3 annually in Europe. The project attacks the problems at their origin with the following objectives * Development of new cutting tool materials and cutting fluids * Reduction of metal solubilization in cutting fluids with at least 90 % * Specification of obtainable machined surface qualities under given machine parameter conditions * Description of water based degreasing formulations with approved degreasing effect and minimised metal solubilization A successful completion of the project will improve quality and productivity substantially and lead to significant environmental benefits.
