Abstract The polishing composition for a centrifugal magnetic-abrasive machine for machining complex profiled workpieces. The composition exhibits ferro-magnetic properties and could be used in all centrifugal and magnetic-abrasive machines but more particularly in the combined centrifugal magnetic-abrasive machines wherein high roughness grades of the machined surfaces are obtained from comparatively low speeds of centrifugal packing and low magnetic field intensity. The composition is made of a 84-86% mixture of abrasive grains and iron-powder; 4-6% of a mixture of chromium sesquioxide, stearine, and oleic acid; 4-6% ground fruit pits or sawdust; and 4-6% of a 3% aqueous solution of triethanolamine soap. In their respective mixtures the abrasive grains are 5-40 mm in size and amount to 16-20%, the iron-powder amounts to 80-84%, the chromium sesquioxide of the 1-10 mm grain size amounts to 55-57%, the stearine amounts to 37-39%, and the oleic acid amounts to 5-7%.
