Excerpt from Cutting Compounds and Distributing Systems: A Treatise on the Kinds of Oils and Compounds Used on Different Classes of Metal-Cutting Tools and Machines, Including Distributing and Reclaiming Systems, Filtering, Sterilizing and Testing MethodsOil or cutting compound is delivered to a metal-cutting tool in order to increase production, to give longer life to the tool, and in some cases to secure a better finish on the work. The functions of an oil or cutting compound may be presented under five heads: (1) To cool the work and cutter. (2) To wash away chips. (3) To lubricate the bearing formed between the chip and lip of the cutting tool. (4) To enable the cutting tool to produce a good finish. (5) To protect the finished product from rust and corrosion. Each of these functions is quite broad and prevents trouble from a large number of causes.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
