Abrasive Slurry Delivery System for Precision Optical Lens Polishing

Product Specifications

Technical details and manufacturing context for Abrasive Slurry Delivery System

Definition

The Abrasive Slurry Delivery System is a critical component of a Precision Optical Lens Polishing Machine. Its primary function is to precisely meter, transport, and uniformly distribute a suspension of fine abrasive particles (the slurry) to the contact point between the polishing tool (e.g., a polishing pad) and the optical lens substrate. This ensures consistent material removal, surface finish quality, and process control during the precision polishing operation. The system typically comprises a slurry reservoir, a pump or pressurized delivery mechanism, flow control valves, and distribution nozzles or manifolds. The abrasive slurry is drawn from the reservoir and propelled through the delivery lines. Flow rate and pressure are precisely regulated to maintain a consistent supply of fresh abrasive to the polishing zone. The slurry is then dispensed onto the polishing pad or directly at the lens interface, where the abrasive particles facilitate the micro-cutting and smoothing of the lens surface. The system is designed for integration into industrial polishing machines, with wetted parts made of corrosion-resistant stainless steel (grade 316L) and chemical-resistant polymers such as PTFE or PVC. It handles slurry particle sizes from 0.05 to 10 μm, operates within a temperature range of 10–40 °C, and delivers flow rates of 0.5–5 L/min at pressures of 0.2–0.6 MPa. Electrical requirements include a supply voltage of 220–380 V AC (IEC 60038) and power consumption of 0.5–1.5 kW. The system offers ingress protection ratings of IP54–IP65 (IEC 60529) and weighs between 50 and 150 kg, with dimensions ranging from 600×400×500 to 800×600×700 mm. These values are reference ranges; actual specifications must be confirmed with the legal manufacturer or supplier for the specific model and application. The system is not a standalone product but a component intended for use in precision optical lens polishing machines.

Working Principle

The system operates by drawing abrasive slurry from a reservoir via a pump or pressurized mechanism. Flow control valves regulate the flow rate and pressure, ensuring a consistent supply to the polishing zone. The slurry is then distributed through nozzles or manifolds onto the polishing pad or directly at the lens interface. The abrasive particles in the slurry perform micro-cutting and smoothing of the lens surface. The system maintains uniform distribution to achieve consistent material removal and surface finish.

Common Materials

Stainless Steel (for wetted parts and tubing), Chemical-resistant polymers (e.g., PTFE, PVC for seals and lines), Abrasive particles (e.g., cerium oxide, aluminum oxide, diamond)
