TYPICAL SPECIFICATION

Note:  Soluble Cutting oils are not recommended to be used for machining magnesium and its alloys.

Velcut 40 Oil this is general purpose emulsifiable oil and forms a milky white emulsion.  It meets the requirements as specified by IS 1115 - 1986 and is suitable for all metals and for all machining operations where emulsifiable oils are normally used.  The most common emulsion strength used for machining ranges from 5 to 10 percent depending on the severity of machining.

hydrochloric acid or saturated salt solution such as Epsom Salt.  By noting the oil quantity that has separated the volume of oil or water to be added in emulsion can be determined.

To Check Oil Concentration:  The oil concentration in an emulsion is checked by drawing a sample in a graduated stopper glass cylinder and breaking the emulsion with

Preparation of Soluble oil emulsion:  In preparing the emulsion of soluble oils with water, the product is always added to the water and not vice/versa to prevent inversion of the emulsion.  The requisite quantity of product is added to one or two parts of water to form a concentrated emulsion which is subsequently diluted with the requisite quantity of water.  The emulsion is applied copiously to flood the work and the tool at the machining area.  This will ensure satisfactory performance.

These products are emulsifiable in water and are a blend of refined mineral oil base stocks, emulsifiers, additives and suitable bactericides.

*     They do not contain ingredients harmful to the operator.

*     They cause no rusting or corrosion of machine, work piece or tool.

We have developed a number of cutting fluids, each grade selectively formulated, to give optimum performance on a wide range of metals.  Velloils cutting fluids have the following characteristics:

There have been great strides in machine tool design and cutting tool materials due to new industrial materials developed higher production demands and the ever smaller tolerances to which components have to be machined.  This has led to corresponding advances in cutting fluid technology.  Cutting fluids play an important role in speeding up production by enabling increased rates of metal removal to be used, and by reducing or even eliminating problems associated with severe and hazardous machine operations.
