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.

SYNTHCUT

Machining and grinding fluids are designed for use on all metals, plastics, glass and composites. These products are engineered to provide total performance, whether running small individual sumps or large central systems. Formulated using today's leading chemical technologies and qualified raw materials, they contain balanced lubrication chemistries to provide optimum results. In addition, our products deliver outstanding  biostability properties, corrosion protection, post-processing synchronisity, low or no foam and complete aqueous compatibility. Synthetic fluids contain no petroleum or mineral oil  it generally consist of chemical lubricants and rust inhibitors dissolved in water. Like soluble oils, synthetics are provided as a concentrate which is mixed with water to form the metalworking fluid. These fluids are designed for high cooling capacity, lubricity, corrosion prevention, and easy maintenance. Due to their higher cooling capacity, synthetics tend to be preferred for high-heat, high-velocity turning operations such as surface grinding. They are also desirable when clarity or low foam characteristics are required. Due to their wet ability, good cooling and lubricity, emulsifiable synthetics are capable of handling heavy-duty grinding and cutting operations on tough, difficult-to-machine and high temperature alloys The appearance of emulsifiable synthetic fluids ranges from translucent to opaque.
Lobol  Synthcut also provides a full line of mist and saw lubricants for "near dry" applications. These eco-based fluids are formulated utilizing natural vegetable base stocks and additives. Lubol   Synthcut  –  is Synthetic type coolant intended for use on ferrous metals and its chemical formula is angled to overcome any difficulties in the cutting and grinding of Cast Iron with soluble media. A reliable small amount of EP additives is present so that a high surface finish can be achieved. Lubol Synthcut    is ideally suited for machining and grinding of Cast Iron. They are the right choice for production grinding where wheel grains must cut continuously without any trace of burn marks. These products can be used for light duty machining operations

ADVANTAGES
SYNTHCUT  fluids have the following qualities which contribute to superior service life
Excellent microbial control and resistance to rancidity for long periods of time;
Nonflammable, nonsmoking and relatively nontoxic.
Good corrosion control.
Superior cooling qualities.
Greater stability when mixed with hard water.
Reduced misting problems; and Reduced foaming problems.
 

Synthetics are easily separated from the workpiece and chips, allowing for easy cleaning and handling of these materials. In addition, since the amount of fluid clinging to the workpiece and chips is reduced, less makeup fluid is needed to replace coolant lost to drag-out.
Good settling properties allow fine particulates to readily drop out of suspension, preventing them from recirculating and clogging the machine-cooling system. Overall, synthetics are easier to maintain due to their cleanliness, they offer long service life if properly maintained and can be used for a variety of machining operations.

 
DISADVANTAGES
Although synthetics are less susceptible to problems associated with oil-based fluids,
moderate to high agitation conditions may still cause them to foam or generate fine mists.
A number of health and safety concerns, such as misting and dermatitis, also exist with the use of synthetics in the shop.
Ingredients added to enhance the lubricity and wettability of emulsifiable synthetics may increase the tendency of these fluids to emulsify tramp oil, foam and leave semi-crystalline to gummy residues on machine systems.
Synthetic fluids are easily contaminated by other machine fluids such as lubricating oils and need to be monitored and maintained to be used effectively .
