Method for depositing oil agent on workpiece |
摘要 |
An oil agent of the kind and amount suitable for a post-step is applied on a workpiece regardless of the kind and residual amount of an oil agent used in a pre-step. A workpiece on which a first oil agent is deposited is immersed in a degreasing solution, taken out of the degreasing solution and cleaned to thereby remove all the first oil agent. Then, the workpiece having all the first oil agent removed is immersed in an oil agent solution to thereby newly deposit a second oil agent of the kind and amount suitable for a post-step on the workpiece.
