JSYAPG‑OILALU oil‑based alumina polishing slurry is a fine‑grinding oily suspension formulated with classified calcined alpha‑alumina abrasive dispersed within refined mineral oil base. It is compounded with oil‑soluble dispersants, extreme‑pressure lubricants and anti‑oxidation additives. This product is dedicated to fine grinding and precision lapping of metal parts, cemented hard‑alloy components and bearing steel workpieces. The oil‑based system forms a continuous lubricating film during gri

Product Detail

Product Detail Page: JSYAPG‑OILALU oil‑based alumina polishing slurry is produced from carefully classified calcined alpha‑alumina powder. The raw alumina undergoes particle‑size screening and impurity removal procedures. Refined mineral oil is selected as the continuous liquid carrier. Special oil‑soluble dispersing agents reduce the sedimentation tendency of dense alumina particles. Extreme‑pressure and anti‑oxidation additives minimize thermal oxidation of the oil medium under high‑friction working conditions, maintaining stable grinding performance during continuous processing cycles.

Bearing steel, hard alloy and precision metal components require high‑quality fine‑ground surfaces before subsequent finishing operations. Water‑based grinding fluids often provide insufficient boundary‑layer lubrication under heavy contact pressure. Poor lubrication will generate excessive frictional heat, which may induce surface burns, local thermal discoloration and micro‑cracks on bearing raceways. Such thermal defects severely shorten the fatigue service life of bearing parts. For hard‑alloy workpieces, thermal stress can trigger tiny edge chipping, resulting in high rejection rate for precision mechanical components.

The oil‑based carrier of JSYAPG‑OILALU builds a consistent protective lubricating film between the grinding plate and workpiece surface. This oil film reduces direct rigid friction between alumina grains and metal substrate. A complete range of particle‑size grades supports sequential processing workflows: medium‑fine grit for removing residual rough grinding marks, ultra‑fine grit for surface leveling before mirror polishing. The slurry is compatible with flat lapping machines, rotary fine‑grinding equipment and semi‑automatic polishing fixtures for batch production of mechanical parts.

During practical processing, technicians shall select suitable abrasive particle‑size grade according to the remaining machining allowance and target surface roughness. Adjust key machine parameters including grinding down‑force, plate rotating speed and slurry feeding volume. For continuous mass‑production circulation, auxiliary filtration is recommended to filter out metal grinding swarf and debris.

Foreign particulate contamination, prolonged high‑temperature storage and direct sunlight exposure must be strictly avoided. High ambient temperature accelerates oil oxidation, thickening of the slurry and irreversible alumina sedimentation. Once solid‑liquid separation occurs and cannot be re‑homogenized through stirring, the slurry should no longer be used for precision fine‑grinding.

Major application fields include fine grinding of high‑precision bearing steel raceways, precision lapping of cemented hard‑alloy mechanical components, surface refinement of carbon‑steel and alloy‑steel mechanical parts.

Store the product in tightly‑sealed original drums within 10‑30℃. Keep away from direct sunlight and heat sources. Sufficient mechanical stirring is required before use for batches with long‑term storage.
