Abstract: An apparatus and method are provided for washing machining debris from machined parts. The apparatus includes a machine transfer housing with front and rear sidewalls, a top, a bottom, an entrance sidewall defining an entrance, and an exit sidewall defining an exit. A transfer line enters the housing at the entrance, extends through the housing and exits the housing at the exit to transport the machined parts through the housing. A header is attached to the top housing wall for delivering a wash solution to the housing. A solenoid valve controls the flow of the wash solution in the header. One or more rotating nozzles are connected to the header for spraying the wash solution in the housing to remove machining debris from the machined parts and the housing walls.
