ABSTRACT:
Disclosed is a method and an apparatus for removing by-product chips, in existing CNC machining center. The apparatus is using parasite driven rotating carousel, capable of moving chips away from the drain of an existing machine. There is a possibility of installing powered feed device with its own controller in case the machine is not equipped with the auger. The method of removing chips is based on shape of the apparatus and the parasite drive, which uses existing machine auger. This auger is normally used to remove chips from the machine into an external collection unit. The apparatus allows operating the machine without interruption, otherwise when such apparatus is not used, chips clog drain holes forcing the machine operator to stop the machine for periodic drain cleaning. The auger itself does not protect the drain from being clogged. The drain cleaning apparatus can be used in the machines of different size. Such apparatus allows for a continuous operation and dramatically improves machine's performance due to the prevention of the drain clog and incessant circulation of coolant.
