<p>A lubricant composition for use in the bonded-abrasive polishing of magnetic heads. It comprises 100 parts by mass of a hydrocarbon solvent and, incorporated therein, 0.001-4.999 parts by mass of an organic onium salt, e.g., tetraoctylammonium bis(trifluoromethanesulfonyl)imide, and 0.001-4.999 parts by mass of a C<sub>8-25</sub> fatty acid, the sum of the organic onium salt and the fatty acid being 0.01-5 parts by mass. With the lubricant composition, sufficient productivity can be maintained in the step of finish polishing of magnetic heads without arousing the breaking or reliability decrease caused by static buildup.</p> |
