JSYAPG‑FAL calcined alumina lapping slurry is an aqueous lapping suspension using high‑grade calcined alumina as the core abrasive. It is compounded with dispersing agents, anti‑sedimentation stabilizers and friction‑reducing lubricants. This slurry is suitable for precision grinding and polishing of metal hardware, optical glass and structural ceramic components. Controlled abrasive grain hardness delivers stable material removal while minimizing deep scratch defects. The concentrated stock slu

Product Detail

Product Detail Page: JSYAPG‑FAL lapping slurry is formulated with calcined alumina obtained from high‑temperature calcination and subsequent precise particle‑size classification. During slurry manufacturing, multi‑stage filtration is performed to remove oversized grit and hard agglomerates. Raw‑material purification reduces trace heavy‑metal impurities to prevent surface staining on finished workpieces. The functional additive system improves particle dispersion in aqueous medium and slows down rapid sedimentation of high‑density alumina particles during circulation on lapping equipment.

Precision lapping serves as a critical intermediate processing step for metal, glass and ceramic components. For machined metal parts, coarse tool marks and burrs generated by CNC machining need to be eliminated to improve surface smoothness and anti‑corrosion performance. Optical glass blanks retain uneven surface texture after cutting and rough grinding; uncontrolled aggressive abrasion would introduce subsurface micro‑cracks which degrade light‑transmission properties. Dense structural ceramics are brittle by nature, and deep surface scratches can become stress‑initiating points under mechanical load, shortening component service life.

Calcined alumina features well‑defined grain hardness and sharp cutting edges. It delivers reliable material‑removal efficiency for rough‑to‑intermediate lapping operations. The built‑in lubricating additives lower instantaneous frictional heat between lapping plate and workpiece, which helps to reduce thermal stress on glass and brittle ceramic substrates. This slurry can be deployed on double‑sided lapping machines, single‑side grinding equipment and rotary polishing platforms for batch processing of industrial components.

Process technicians can adjust working concentration by diluting the concentrated slurry with deionized water. Lapping quality can be optimized by modifying key process parameters including applied down‑force, lapping plate rotating speed and slurry feeding flow rate according to workpiece material hardness and target surface roughness.

Foreign chemical contamination, prolonged high‑temperature storage and freezing conditions must be strictly avoided. Freezing will destroy the dispersion‑stabilizing system and cause irreversible hard sedimentation of alumina particles. Once hard sediment cannot be re‑dispersed through sufficient stirring, the slurry should no longer be used for precision lapping.

Major application fields include precision lapping of hardened metal components, intermediate grinding and finishing for optical glass blanks, surface refining of dense structural ceramic workpieces.

Store the product in tightly‑sealed original plastic drums within 5‑30℃. Keep away from direct sunlight and freezing conditions. Sufficient stirring and circulation is required before using long‑term stored batches.
