INDUSTRIAL SPECIALTIES l Petroleum Specialties represent a group of products which find wide application in the various processing industries. These products are primarily used in processing for manufacture of high quality finished goods. In most cases the petroleum specialties become part of the finished articles. l They impart desirable properties to raw material to facilitate their processing into finished goods. l They assist in the processing operations of the manufactured articles. l They improve quality and serviceability of the materials being processed. l They generally form part of the manufactured articles imparting them desired properties. l They enhance the sales appeal of the finished articles.

CUTTING OILS CUTTING OPERATION l Chip formation in metal cutting l Heat sources l Built up edges l Cutting fluid paths
CUTTING OPERATION l Pressure l Friction l Heat
NECESSITY OF CUTTING FLUID l Heat generation by external friction is reduced / minimised by placing a suitable lubrication film between the rubbing surfaces of work piece, tool and chip l Cooling / lubrication of contact surface between tool, work piece and chip results in improved finish, higher cutting speeds, depth of cut, reduced power consumption and reduced rate of tool wear. l Prevents the welding/seizure taking place between tool and work piece resulting from high pressure and high temperatures.
FUNCTIONS OF CUTTING FLUID l To lubricate the contacting surface of tool, work piece and chip l To cool work piece, tool and chip l To prevent local welding of metal particles to the tool ( minimise built up edges ) l To flush swarf from the cutting area
CHARACTERISTICS OF THE CUTTING FLUIDS l Cause no rusting and corrosion of machines, work piece and tool l Cause no discoloration or staining of the metal l Should not smoke or foam in use l Have no objectionable odour l Should not decompose chemically in use l Should not be harmful to the machine operator

QUENCHING OILS BASICS OF HEAT TREATMENT l When steel is heated and cooled, the iron it contains undergoes a structural change. Hot steel at its critical temperature and above is a solid solution of carbon in face - centered - cubic - iron - Austenite. When Austenite is cooled rapidly it is transformed to Martensite - hardest possible with body centred structure. l This cooling can be done by the process known as Quenching.
