Abstract

Abstract - A milling machine is a machine tool used to machine solid materials. The Nick Milling Machine used in Bearing Department of a well known Engine Manufacturing Ltd. Company in Pune, operates on work provided by the compressor. The input air pressure provided to this machine is about 5 Bar. This compressed air is used for operating the punch bringing about the actual nicking operation. A nick is required on each bearing halve for joining the two bearing halves. After completion of the punching operation, the exhaust (waste) air is given out to the atmosphere (approximate 4.5 Bar) . Some additional compressor work is required for applications like alignment of the bearing , cleaning of the bearing surface, cutter surface cleaning etc. after cutting the nick on the bearing halve, since the exhaust (waste) air from the nick milling machine is approximate 3 Bar obtained at receiver outlet considering piping loses . Instead of using additional compressor work for the above said actions, we can reuse the same exhaust air with the help of efficiently designed receiver, distributor system, piping system, inlet and outlet nozzles corresponding to exhaust air pressure (approximate 3 Bar) and corresponding to the above mentioned applications.
