Abstract:
An apparatus for controlling cutting fluid of a processing machine having a cutting fluid supply loop, said apparatus comprising:a cylindrical rotor having a main passage inside extending along a longitudinal axle thereof and at least one branch passage in communication with said main passage, said main passage having an end in communication with the cutting fluid supply loop and the other end closed; a power source for driving said rotor to rotate; a control mechanism having an encoding device and at least one sensor, said encoding device being mounted on said rotor and moving therewith, said sensor being fixed at a fixed position corresponding to said encoding device; and a processor having a built-in control serial code and being capable of ordering the power source to drive the rotor to rotate based on the built-in control serial code, once said sensor detecting a code from the encoding device identical to the built-in control serial code when the processor orders the power source to drive the rotor to rotate based on the built-in control serial code, the power source being ordered by the processor to stop said rotor at a predetermined angle corresponding to the built-in serial code.
