Book excerpt: "Cutting and grinding fluids at one time were considered little more than a necessary nuisance. However, they are something the metal working industry cannot do without. Today, thousands of blends of fluids provide the necessary lubricity and cooling to allow heavier feeds, higher speeds, and longer tool life demanded in the modern machining industry. Metal working fluids today need not be a nuisance if properly selected, applied, and maintained. This book provides comprehensive information on how to successfully select, apply and maintain cutting and grinding fluids for maximum productivity, minimum waste, and safe performance."--Back cover.
