ABSTRACT:
A lubricating mixture of a lubricant and air is supplied to a cutting location by a lubricating tool with a spring biased piston dividing a cylinder into an air chamber and a lubricant chamber. The air chamber is connectable to a pressurized air source. The lubricant supply chamber is selectively connectable through a control valve to a lubricant source or to an exchangeable lubricant and air mixing attachment also connected to the pressurized air source. The attachment includes three flow restrictors. Two restrictors feed air and lubricant to a mixing area. One restrictor feeds the mixture to an output. Different sets of restrictors with different flow restricting characteristics provide an exact mixture dosage for satisfying any cutter lubricating requirement. It is merely necessary to replace one attachment by another attachment having different flow restricting characteristics.
