Machine tool chip flushing apparatus and method

A method for washing debris from machined parts in a transfer station, said transfer station having a housing with front and rear sidewalls, a top wall, a bottom, an entrance sidewall defining an entrance, an exit sidewall defining an exit, a transfer line entering said housing at said entrance and exiting said housing at said exit to transport said machined parts through said housing, and a header for delivering a wash solution to said housing through one of said housing walls, said method comprising the Steps of;

• controlling the flow of said wash solution in said header;
• connecting at least one rotatable nozzle to said header;
• directing said wash solution through said nozzle and rotating said nozzle;
• spraying said wash solution in said housing and removing debris from said machined parts and said housing walls;
• and
• extending said nozzle from said header in response to fluid pressure of said wash solution in said header exceeding a preselected amount, and retracting said nozzle towards said header in response to fluid pressure of said wash solution in said header falling below a preselected amount.
