METAL WORKING FLUIDS
WATER SOLUBLE
VELCUT 40
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.
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:
*

They cause no rusting or corrosion of machine, work piece or tool.
They cause no discolouration or staining.
They do not smoke or fog in use.
They do not have objectionable odour.
They do not decompose chemically in use.
They retain their physical property in use.
They do not contain ingredients harmful to the operator.
These products are emulsifiable in water and are a blend of refined mineral oil base
stocks, emulsifiers, additives and suitable bactericides.
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.
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
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.
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.
Note: Soluble Cutting oils are not recommended to be used for machining magnesium
and its alloys.

METAL WORKING FLUIDS NEAT
(STRAIGHT)
VELCUT ST - 23
A fluid is typically sprayed onto cutting tool surfaces during the machining
of metal automotive components. The cutting fluid greatly enhances
the machining process and allows the mass production of components
that meet engineering quality requirements. Unfortunately, the spraying
and the high speed cutting action often atomize the fluid into very
small droplets, creating a persistent, and fog - like mist in the plant. The generation
of even small amounts of mist can become a serious concern because of
the nearly continuous, high production machining activity. Oil mist can remain
in the suspended for many hours and will eventually settle over large areas
of the plant on floors, machinery and air ventilation work. It may also
deposit on pools on plant roofs via general ventilation duckwork exhausts.
Negative effect of oil mist includes poor air quality on worker’s breathing
zone, housekeeping / safety issues, fire propagation upon introduction of a
spark, and environmental concern if oil on the roof is carried
down storm water drains. Current health and safety regulations giving
the maximum permissible concentration is being scrutinized.
We have developed cutting oil which has animist properties and also
mist
suppressing character in straight oil grades and proved to be successful in
plant study. Our VELCUT ST - 23 grades are superior in all respects
and
this technology could complement engineering control measures as:
1.
Reducing the mist loading to collectors would extend filter life
and reduce maintenance costs.
2.
Reducing oil mist deposition would improve housekeeping and fire
safety in the plant and associated ventilation equipment.
3.
Mist suppression would especially benefit older machining operation
where mist collection equipment doesn’t exists and or cannot
be effectively retrofitted.

This is medium viscosity dark brown oil containing active sulphur, chlorine and oiliness
additives. It is suitable for all machining operations on high tensile steel and for less
severe operations on stainless and heat resistant alloys. It is also recommended for gear
hobbing, thread cutting machines etc…
