In flat glass processing, arrissing and seaming operations require a balance between stock removal, edge control and finish consistency. The tooling must remove material efficiently while helping to reduce visible edge defects and maintain a repeatable finish across production.
DK Holdings Limited manufactures Flexible Diamond Belts for glass arrissing and seaming applications from its ISO-certified production facilities in the United Kingdom. The company was one of the early developers of Flexible Diamond Belts for the glass manufacturing market and has continued to develop the range through in-house testing, customer feedback and live production experience.
The belts are manufactured using DK’s Flexible Diamond material, which combines the cutting action of diamond with a backing material that provides both strength and flexibility. This allows the belt to follow the working area more effectively than a rigid format while maintaining controlled abrasive performance during wet processing.
The manufacturing process creates diamond islands of consistent size and shape with regular spacing. This pattern allows slurry to be washed away with the lubricant or coolant during use, reducing the risk of clogging and supporting efficient stock removal and finishing.
For glass arrissing and seaming, belt size, grit grade, machine type, glass thickness, contact pressure, coolant use and production speed all influence the final tooling recommendation. DK manufactures Flexible Diamond Belts in a variety of sizes, with 1,180 by 80 millimetre among the most popular sizes used for arrissing and seaming operations.
The belts can be supplied in a range of diamond grades, depending on whether the customer requires heavier stock removal, edge refinement or a finer finish. DK’s technical team works with customers to select a belt grade or sequence that reflects the machine set-up and production requirement.
Alongside popular standard sizes, DK Holdings can manufacture belts to suit a wide range of glass processing machines. This supports processors who need tooling built around existing equipment rather than adapting production around a standard product.
Flexible Diamond Belts form part of DK’s wider Flexible Diamond range, which also includes discs, hand pads and sheets for wet grinding, polishing and finishing applications.
DK Holdings is showcasing its Flexible Diamond Belt range during glasstec 2026, Düsseldorf, from October 20 to 23, in Hall 11, Stand B24. Visitors will be able to discuss belt applications for glass arrissing and seaming, as well as wider precision diamond tooling requirements for glass processing.
