Choosing the Right Lens Blocking Pad Size for Your Edging Machine

When it comes to precision in optical lens processing, selecting the correct lens blocking pad size for your equipment is essential. Different edging machines are compatible with different pad sizes, and using the right match ensures stability, adhesion, and accurate lens alignment throughout the process.

Compatibility by Equipment Type

  • Essilor Machines: Compatible with 33mm × 17mm pads

  • Nidek Edging Systems: Best suited for 24mm × 30mm or 24mm × 31mm pads

  • Briot Machines: Often used with 22mm × 25.5mm or 24mm × 28mm pads

  • Topcon or Huvitz Equipment: Commonly work with 20mm × 28mm or 18.5mm × 29mm

  • Manual Blocking Systems: Use larger pads like 20mm × 32.5mm or 20mm × 31mm

Why Pad Size Matters

Using the correct pad size directly influences the accuracy of the lens cutting and polishing. It also helps reduce waste, avoid slippage, and prevent lens misalignment. Pads that are too small may lose grip during edging, while oversized ones might interfere with machine sensors or lens holders.

Tips for Optical Labs

  • Refer to the manufacturer’s specifications

  • Keep an inventory of multiple pad sizes

  • Conduct regular quality control tests

Using the correct optical lens pad is a small but vital step in achieving high-quality lens outcomes.
