    The main tasks of the cooling and lubrication fluid are:

  • cooling,
  • lubrication,
  • removing chips,
  • corrosion protection.

    General recommendations for the selection of the cooling and lubrication fluid in relation to the cutting speed and the chips section are:

  • Small cutting speed and small chips section: without cooling and lubrication;
  • Small cutting speed and large chips section: poor cooling and great lubrication;
  • High cutting speed and small chips section: great cooling and poor lubrication;
  • High cutting speed and large chips section: great cooling and great lubrication.

In case it is required higher cooling than lubrication it is needed to provide plentiful coolant supply to the cutting zone. In case that there are more friction it is needed to lead the lubrication fluid to the place of greatest friction.

    Cooling and lubrication fluids can be classified into the following main groups:

  • Clean cutting oils in which prevails lubricating effect in relation to the cooling;
  • Oil emulsions which are composed of two liquids and in which one is in tiny droplets dispersed in another;
  • Synthetic cooling and lubrication fluids.
