Diamond Weaver

What Diamond Weaver does

Diamant Weber AG is a privately held Swiss specialty manufacturer of diamond and CBN (cubic boron nitride) precision grinding and dressing tools, founded in 1896 and headquartered at Industriestrasse 12 in Winterthur. The company designs and produces a comprehensive portfolio spanning eight dressing-tool families — including profile diamonds, single-grain and multi-grain dressers, the DIAMOLL dressing wheel line, the internally cooled DIAVLISS dressing plates, PCD/CVD dressing plates, profile rolls and form rolls — alongside four grinding-wheel families for flat/round, profile, internal and tool-grinding applications. Underlying technology covers all four major bond systems for superabrasives: vitrified/ceramic, resin, metallic and galvanic, with grit sizes from B54 to B181, wheel diameters up to 800 mm, and cutting speeds approved to vc=125 m/s. The company's proprietary vitrified bonded CBN platform, developed in 2005, and its internally cooled DIAVLISS dressing plates constitute its main technical differentiators.

The firm sells directly to industrial customers across six verticals — aerospace, medical technology, mechanical engineering, tool making, watch making and automotive — via a sales-led go-to-market with an external field sales force (Aussendienst) providing on-site technical consultation and process analysis. The revenue model combines one-time hardware sales of standardized and custom tools with recurring professional services: a dressing service for wheels up to 750 mm diameter, an EDM eroding service producing complex radii down to 0.125 mm at ±0.02 mm tolerance, and tool regeneration/repositioning services. Pricing is quote-based and not publicly disclosed. The company holds ISO 9001 certification and SWISS LABEL membership, ships worldwide from its single Winterthur production site, and emphasizes short lead times on custom special designs as a core commercial promise.

Products and services

• Profile Diamonds (Profildiamanten) High-precision profile diamonds used for dressing complex grinding wheel profiles. Manufactured in various angle and radius configurations in synthetic versions, offering equivalent service life to natural diamonds.
• Single-Grain Dresser (Einkornabrichter) Classic dressing tools with natural or synthetic diamond tips (mono or polycrystalline), used for internal grinding operations and small batch dressing of grinding wheels.
• Multi-Grain Dresser (Vielkornabrichter) Economical natural diamond dressing tools with large diamond cross-sections for efficient high-feed dressing on cylindrical and internal grinding machines.
• DIAMOLL Dressing Wheels (Abrichträder) Highly efficient dressing tools with special diamonds evenly arranged on the circumference, held by sinter bonding. Used for dressing straight grinding wheels and profiling, suitable for medium and coarse grits.
• DIAVLISS Dressing Plates High-quality diamond dressing plates available in synthetic (MKD/CVD) or natural diamond, used for single-profile straight dressing and complex profile dressing operations. Features internal cooling (DIAVLISS IK) for extended tool life.
• PKD & CVD Dressing Plates Triangular PCD (polycrystalline diamond) and CVD dressing plates with three usable dressing corners, suitable for internal grinding and profiling external cylindrical grinding wheels.
• Diamond Dressing Wheels (Diamant Profilrollen) High-precision profile dressing rolls developed for long tool lives and maximum precision at short dressing intervals. Achieves profile accuracies in total tolerance range of ≤ 0.002 mm.
