Choose between advanced metal bond and versatile resin bond systems to perfectly match your application needs.

Mastering the Challenges of Cutting Optical Glass

Optical glass presents unique cutting challenges due to its brittle nature, stringent surface finish requirements, and high material value. Our diamond discs are meticulously designed to address these issues:

• Minimize Chipping & Cracking: Employing high-quality, precisely graded diamond particles ensures sharp, efficient cutting action that significantly reduces mechanical stress and thermal damage, preserving the integrity of the delicate glass material.
• Ensure High Precision & Minimal Waste: These discs create exceptionally narrow, precise cuts (kerfs or “slits”), minimizing valuable material loss and enabling the accurate dimensioning essential for optical components.

Choosing Your Bond: Metal vs. Resin for Optimal Results

The choice of bond system is critical for optimizing performance based on your specific optical glass type, cutting parameters, and desired finish quality:

• Metal Bond Discs: Engineered for maximum durability and wear resistance, delivering the longest possible operational life. Metal bonds allow for the construction of ultra-thin discs (down to 0.3mm thickness), ideal for minimizing kerf loss. They typically utilize diamond grit sizes ranging from 60 to 600, making them well-suited for general-purpose high-efficiency cutting and processing harder types of optical glass.
• Resin Bond Discs: Offer a softer, more free-cutting action, which often results in superior surface finishes and minimized edge chipping, particularly beneficial for more sensitive or brittle glass materials. Resin bonds can incorporate a much wider range of finer diamond grits (from 80 up to 2000), enabling the achievement of demanding, near-polish-ready surfaces directly from the cutting step. Their typical thickness starts from 0.5mm.

Key Performance Advantages

Optimized specifically for optical glass, these diamond discs consistently deliver the performance needed for high-quality results:

• High Sharpness: Enables fast, efficient cutting operations while requiring lower processing forces, minimizing mechanical stress on delicate glass materials.
• Minimal Kerf Width: Achieves ultra-thin, precise cuts (“slits”), maximizing the yield from valuable optical glass blanks and enabling the production of intricate components.
• Extended Durability: Offers substantial operational life within the selected bond system category (metal or resin), contributing to cost-effective production cycles and reduced tooling costs.
• Excellent Edge Quality: Produces clean, smooth cut surfaces with minimal chipping or subsurface damage, meeting the stringent quality control standards demanded by the optical industry.
