Precision Optical Lens Grinding Machine

Product Specifications

Technical details and manufacturing context for Precision Optical Lens Grinding Machine

Definition

This standalone industrial machine is used in optical manufacturing facilities to grind lens blanks to specific spherical or aspherical curvatures. It employs diamond-impregnated grinding wheels to remove material from glass or crystal substrates with micron-level accuracy. The machine is essential for creating the base optical form before polishing and coating processes. It features automated control systems for maintaining consistent surface profiles across production batches.

The machine accommodates lens blanks up to 200 mm in diameter. The grinding spindle operates at speeds between 3,000 and 10,000 RPM, with a spindle motor power range of 2.2 to 7.5 kW. Positioning accuracy is ±0.005 mm, verified according to ISO 230-2. The grinding wheel diameter ranges from 150 to 300 mm, affecting surface finish and edge quality. Achievable surface roughness (Ra) is 0.01 to 0.05 μm, per ISO 4287. Coolant flow rate is 20 to 60 L/min for heat dissipation. Total power consumption ranges from 5 to 15 kW. The machine operates in ambient temperatures of 10 to 40 °C and relative humidity of 30 to 85%. It has an IP54 protection class per IEC 60529. Machine weight is 1,500 to 3,000 kg, and footprint dimensions are 2000×1500×1800 mm (L×W×H).

Constructed from stainless steel, cast iron, and aluminum alloy, the machine is designed for durability and stability. These values are reference ranges; verify model-specific specifications and standards with the legal manufacturer or supplier before procurement or use.

Working Principle

The machine uses rotating diamond-impregnated grinding wheels that contact the lens blank at controlled angles and pressures. Material is removed through abrasive action while computer-controlled positioning systems maintain precise curvature. The workpiece is held in a fixture, and the grinding wheel moves along programmed paths to generate the desired spherical or aspherical profile. Coolant is circulated to dissipate heat and flush debris. The process is monitored to ensure consistent surface quality across production batches.
