    I. INTRO DUCTIO N
    Minimum Quantity Lubrication (MQL) has increasingly found
    its way into the area of metal cutting and in many areas, has
    been established as an alternative of conventional flood
    coolant method. In contrast to flood lubrication system
    minimum quantity lubrication uses few droplets of coolant
    mixed with compressed air in the form of mist.
    MQL is the process of applying minute amounts of high - Figure 1
    quality lubricant directly to the cutting tool/work piece
    interface instead of using traditional flood coolants. MQL
    minimizes your environmental impact by significantly II. WO RKING
    reducing fluid usage and eliminating the need for coolant
    treatment and disposal. These near-dry machining benefits are
    multiplied further when using 100% biodegradable lubricants
    which are formulated from renewable plant-based oils. When
    considering these facts along with the performance benefits of
    biodegradable lubricants and MQL, it becomes obvious that
    this is the future of metal cutting fluid.
    The lubricant is sprayed with the help of external supply
    system which can be one or more nozzles. The amount of
    coolant used in MQL is about 3-4 order magnitude less than
    the amount commonly used in flood cooling condition. For
    example up to 10 liters of coolant is used in flood coolant type
    lubrication system.
    In MQL lubrication is obtained via the lubricant, while a
    minimum cooling action is achieved by the pressurized air that
    reaches the cutting surface. When the MQL is applied to the
    tool rake tool life is no different from dry condition but MQL
    applied to the tool flank can increase tool life. In machining,
    excessive heat is generated using flood coolant will reduce
    thermal shock causing tool failure. Hence MQL will promote

    handled is limited. As your requirement increases, your
    compressor size keeps going up.

    The next generation of air compressor is the screw


    compressor. Here the machine consists of a part called the
    aired, which is the heart of the device. It contains two lobes cut
    in a particular profile along which the air flows. The airend is
    generally crowned with an intake valve. The shaft of the aired
    is coupled to a prime mover (an engine or an electric motor).
    The prime mover rotates the lobes which creates a vacuum in
    the aired case. This gives a pulse to the intake valve which
    opens according to the amount of vacuum created and sucks in
    air. The air then traverses along the lobes and gets discharged
    either to a storage tank or for end use. Screw compressors
    provide a more consistent flow of air than their Reciprocating
    counterparts and are considered more reliable.

    Centrifugal air compressor functions just like a pump. It has a


    casing which contains a blade profile coupled to a prime

    C. Micro Pump
    A Micro pump is used to pump the lubricant.The type of
    Micro Pump used is Gear Pump. The primary function of Gear
    pump is to pump the lubricant from the storage tank to the
    Mixing Chamber where it is mixed with pressurised air. The
    power supply to the pump is given with the help of motor
    which is coupled to the pump with the help of a love couple
    joint.

    notable improvements over dry and conventional
    flood cutting fluid supply.
    MQL technique provides reduced tool wear,
    improved tool life and better surface finish mainly by
    Reducing the friction in the chip tool and work piece
    tool interfaces, which maintains sharpness of the
    cutting edge?
