Investigation of cooling and lubricating liquids

Abstract

Considering increasing waste disposal problems in the area of cooling and lubricating liquids as well as their potential of health hazard and environmental endangering the question is to ask to what extend the customary way of cooling and lubrication in metalworking is still in keeping with the times. Several approaches to solve this problem seem to be suitable to guarantee a better human and environmental agreeableness as well as a smaller consumption. To make a reliable statement about the possibilities for the application of reducing strategies and their limits, fundamental knowledge about the process-changing characteristics of cooling and lubricating liquids in general is required. Concerning this, it is important to know more about the mechanism which enables the moistening of the tool's cutting edge with cooling lubricants in spite of, especially in case of turning, high pressure, high temperatures and opposite kinetics in the cutting area.
