METAL WORKING OIL
 
The great flexibility and versatility of the different types of machining method are particularlysignificant in the metal working industries. Although for some years now there has been growing trend towards non-cutting (forming) methods for work piece quality reasons and to save material and process costs, this has still not had any obvious effects on the volume share of lubricants. This is also apparent from the machine tools statistics. The dramatic changed prophesied in the nineteen seventies did not take place  in the nineteen eighties and nineties.
Because of the particular significance of cooling for the cutting operation, this process is called cooling lubrication and the fluids used are called coolants. Apart from this term “Coolant” which is commonly used in general practice, there are also numerous others. Terms for specific application such as, for eg. cutting oils, grinding oils, reaming oils, deep hole drilling oils and honing oils
 
MACHING OF METALS
  • Water Based Cutting Fluids (Soluble Cutting Oils)
  • Neat Cutting Oils
The following points concerning the storage and use of soluble oils are important.
 
STORAGE
Exposure of packages to moisture or to excessive heat or cold should be avoided.
 
MIXING
To make the emulsion, add the necessary quantity of oil to the water (never the water to the oil), meanwhile stir constantly. Do not use hot water or steam. Use absolutely clean vessels.
 

WATER BASED CUTTING FLUIDS

  • LUBOL - CUTNOL - N.

  • LUBOL - CUTNOL - XN.

  • SYNTHCUT SS. (semi Syenthetic).

  • SYNTHCUT OILS.

  • QUENCHEN OILS.

  • METCUT OILS.

  • FERCUT OILS.

  • HONILE OILS.

SYNTHCUT SS : SEMI SYNTHETIC CUTTING FLUID

SYNTHCUT SS  is a unique combination of lubricity additives, rust preventive chemicals, wetting agents and boundary lubricants resulting in a truly biostatic metal working coolant. Biostatic fluids provide only minimal nutrient sources for microbial growth. The result is greatly extended sump life with virtual elimination of biocides and other tank side additives. SYNTHCUT SS  contains exceptional lubricity properties making it an ideal choice for use with steel, stainless and aluminum alloys in operations of moderate to high severity. Semisynthetics  are essentially a hybrid of Soluble oils and synthetics. They contain small dispersions of mineral oil, typically 2 to 30 percent, in a Water-dilutable concentrate. The remaining portion of a semi-synthetic concentrate consists mainly of emulsifiers and water. Wetting agents, corrosion inhibitors and biocide additives are also present.
Semisynthetics are often referred to as chemical emulsions or preformed chemical emulsions since the Concentrate already contains water and the emulsification of oil and water occurs during its production. The high emulsifier content of semi synthetics tends to keep suspended oil globules small in size, Decreasing the amount of light refracted by the fluid. Semi synthetics are normally translucent but can vary From almost transparent (having only a slight haze) to opaque . Most semi synthetics are also heat Sensitive. Oil molecules in semi synthetics tend to gather around the cutting tool and provide moreLubricity. As the solution cools, the molecules  redisperse.

ADVANTAGES

Like synthetics, semi synthetics are suitable for use in a wide range of machining applications And are substantially easier to maintain than soluble oils.
 They provide good lubricity for moderate toHeavy duty applications.
They also have better cooling and wetting properties than soluble oils, allowing users to cut at higher speeds and faster feed rates . Their viscosity is also less than that of a soluble oil, Providing better settling and cleaning properties.

Semisynthetics provide better control over rancidity and bacterial growth, generate less smoke and oil mist (because they contain less oil than straight or soluble Oils), have greater longevity, and good corrosion protection.
Disadvantages. Water hardness affects the stability of semisynthetics and may result in the formation of Hard water deposits. Semisynthetics also foam easily because of their cleaning additives and generally offer less lubrication than soluble oils.
