Cutting Fluids

subject

description

This chapter provides comprehensive knowledge regarding cutting fluids (CFs), their classifications and basic categories, including non-water-miscible, water-miscible and water-based CFs. Main properties and application areas of these three CFs are characterized and specified. Such effects as cooling, lubricating and processing (i.e., the influence on the behaviour of the cutting process) resulting from supplying CFs are outlined. The strategies of delivering CFs to the cutting zone, including flooding, external and internal supply of pressured CFs, along with minimum-quantity lubrication techniques as well as cryogenically cooled gases (CO2 snow and liquid nitrogen (LN2)) are described. Some advanced constructions of cutting tools (such as turning tools, deep hole drills and milling cutters) allowing the application of high-pressure cooling, along with relevant fluid delivery systems offered by the world-leading cutting tools’ manufacturers, are presented. Similarly, cutting tools and installations for cryogenic machining used for turning and milling operations of different machined materials including Inconel and titanium alloys are outlined. The environmental issues related to the maintenance and disposal CFs are specified and discussed.
