Discussion on "Soluble and cutting oils" at the Glasgow Section of the Institution

MR. J. WRIGHT : I personally thank Mr. Wingfield for the excellent lecture and should like to raise the question of the "loading " of the soluble oil, no remedy for that having been mentioned. Would the lecturer recommend any form of filter for the purpose ? MR. WINGFIELD : I presume you refer to dirty oil. MR. WRIGHT : Not exactly. I had in mind the loading of the lubricant by fine particles of metal or abrasive, practically powder. MR. WINGFIELD : The best method is to use a separator. Soluble oil seeds are so cheap, however, that it does not pay to clean them.
