Introduction to Grinding Fluids 261

Introduction to Grinding Fluids provides an overview of the uses, types, and selection considerations of grinding fluids, or coolants, used in various machining operations. Appropriate grinding fluid use depends on the type of operation, machine tool, and combination of tool and workpiece materials. The basic types of grinding fluids include various combinations of oils, water, chemicals, and additives, and are classified by their contents. The class describes each category of fluid, its optimal uses, benefits, and drawbacks, as well as ideal delivery methods, maintenance, and basic fluid safety and disposal. Selecting, using, and maintaining the appropriate grinding fluid is a key factor in the success of a grinding operation. Proper coolant application can optimize wheel performance and improve finished parts, reducing scrap and tool cost. Additionally, awareness of grinding fluid hazards and maintenance can increase workplace safety and reduce coolant costs.
