Product Specifications

Technical details and manufacturing context for Precision Optical Lens Polishing Machine

Definition

The Precision Optical Lens Polishing Machine is a specialized industrial equipment designed for the final surface finishing stage in optical lens manufacturing. It employs advanced polishing techniques to achieve ultra-smooth surfaces with nanometer-scale roughness, critical for minimizing light scattering and maximizing optical performance. This machine serves as essential capital equipment in the optical instrument supply chain, enabling manufacturers to produce high-quality lenses for cameras, microscopes, telescopes, and medical imaging devices. Its automated operation ensures consistent results while reducing manual labor requirements in precision optics production facilities.

Key specifications include a maximum lens diameter of 200 mm, surface roughness range of 0.1–1.0 nm Ra (ISO 4287), polishing speed of 50–500 rpm, pressure control range of 0.1–0.5 kPa, positioning accuracy of ±0.01 mm (ISO 230-2), power consumption of 3.5 kW, spindle speed range of 100–2000 rpm, polishing time per lens of 1–5 minutes, air supply pressure of 0.5–0.7 MPa (ISO 8573-1), operating temperature range of 10–40 °C, relative humidity range of 30–80% RH, machine weight of approximately 1500 kg, and footprint of 1800×1200×1800 mm with safety enclosure. Materials on file include stainless steel 304, aluminum alloy 6061, polyurethane polishing pads, and ceramic abrasive slurries.

This equipment is intended for use in controlled industrial environments. Operators must verify model-specific values and standards with the legal manufacturer or supplier before procurement or operation. The listed standards serve as procurement references, not certifications of compliance. Always confirm that the machine meets your specific application requirements.

Working Principle

The machine uses rotating polishing pads with precisely controlled abrasive slurries to gradually remove microscopic material from lens surfaces through mechanical abrasion. Programmable pressure, speed, and motion patterns achieve specified surface roughness and flatness. The process involves a polishing spindle that rotates at speeds between 50 and 500 rpm, while the workpiece is positioned with high accuracy. The abrasive slurry, typically ceramic-based, is applied to the polyurethane pad, and the pressure is controlled within 0.1–0.5 kPa. The motion patterns are designed to ensure uniform material removal, resulting in a surface finish with roughness as low as 0.1 nm Ra. The machine operates within a temperature range of 10–40 °C and requires clean dry air at 0.5–0.7 MPa. The entire process is automated, reducing manual intervention and ensuring consistency.
