CUTTING OPERATION

Pressure

Heat

NECESSITY OF CUTTING FLUID

Heat generation by external friction is reduced / minimised by placing a

suitable lubrication film between the rubbing surfaces of work piece, tool and

chip

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.

Prevents the welding/seizure taking place between tool and work piece

resulting from high pressure and high temperatures.

FUNCTIONS OF CUTTING FLUID

To lubricate the contacting surface of tool, work piece and chip

To cool work piece, tool and chip

To prevent local welding of metal particles to the tool

( minimise built up edges )

To flush swarf from the cutting area

CHARACTERISTICS OF THE CUTTING FLUIDS Cause no rusting and corrosion of machines, work piece and tool

Cause no discoloration or staining of the metal

Should not smoke or foam in use

Have no objectionable odour

Should not decompose chemically in use

Should not be harmful to the machine operator

CARE OF CUTTING FLUIDS (SOLUBLE TYPE)

Do not use hard water above 500 ppm for making emulsions

Keep pH of emulsion at 9

Remove chips and fines regularly

Aerate the emulsion periodically

Clean the system thoroughly when changing the oil

Avoid oil blanket on the surface

Bacterial treatment of the emulsion

Keep the emulsion under circulation during weekly shut down

CARE OF CUTTING FLUIDS (OIL TYPE)

Remove chips and fines regularly

Remove the sludge daily

Before and after work , wash hands & forearms and apply suitable

barrier cream

Do not wear oily clothes

Wear protective clothings

Use splash guards

TRIMOFINS IN PREFERENCE TO KOOLKUTS

When more lubrication is required between the contacting surfaces

When it is necessary to reduce friction between the tool and work

piece to maximum extent

In situations where it is necessary to prevent local welding of metal

particles to the tool face. Sulfurized additive type straight cutting oil

are best suited for this purpose

For machining of magnesium and its alloys, it is necessary to use

straight cutting oils as magnesium can combine with oxygen in water

and can create fire hazards

QUENCHING OILS

BASICS OF HEAT TREATMENT

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.

This cooling can be done by the process known as Quenching.

- Fastest rate of cooling

C. Liquid Cooling Stage - Formation of vapour bubbles is stopped

- Cooling by conduction and convection - Rate of cooling is slower compared to VT Stage.

the ambient temperature

• Non Corrosive

• Non Staining

• Non toxic

CHARACTERISTICS OF ROLLING OIL• Proper viscosity.
