RATIONALISATION OF OIL PURCHASES: Some Aspects of Cutting Oil Surveys Available to Purchase

DURING the past fifteen to twenty years the demands of the engineering industry have resulted in the development of a great number of new ferrous and non‐ferrous alloys, the efficient use of which has necessitated the development of new methods of fabrication and production. Manufacturers of machine tools and other plant have enabled industry to maintain its high position in world markets by producing large numbers of special purpose and high production machines for this purpose. The successful operation of these machines depends almost entirely upon the lubricants, metal cutting and drawing oils, etc., available and developments in this field have likewise been considerable.
