らの面に強固に付着している油分を確実に取除く。When the pallet 31 is fed into the basket 15 located in the upper chamber 11, the lifting cylinder 16 then moves the basket 15 into the cleaning liquid stored in the lower chamber 12. And the workpiece W is moved up and down so as to float, and at the same time, a control circuit (not shown) causes a solenoid valve V communicating with the lower nozzle 18u.
0 is opened, and the liquid in the cleaning liquid tank 19 is discharged from the lower nozzle 18u into the liquid in the lower chamber 12 by the pump P, and while stirring the cleaning liquid strongly, a part of the cleaning liquid is partially stirred into the shaft hole and the outer periphery of the workpiece W. Along the surfaces, the rocking action applied to the object to be processed W and the oil firmly adhered to these surfaces are reliably removed.
