SUPERIOR GRINDING PERFORMANCE ——---— Synthetic diamond wheel grit products specifically developed for applications in metal, electroplated, resin and vitrified bond tools.

E X TREME PERFORMANCE SY N THE TIC DIAMOND GRI T S The PremaDia range encompasses synthetic diamond wheel grit products specifically developed for applications in metal, electroplated, resin and vitrified bond tools. The product range extends from PremaDia PDA999, which is a high strength crystalline abrasive suitable for demanding applications and high production rates, to the micro-chipping PremaDia PDA321 and PDA211, particularly suitable for grinding cemented tungsten carbides and hard ceramics. The products are ranked in terms of their relative particle characteristics in the PremaDia...

T HE PRODUC T R ANGE The PremaDia range encompasses synthetic diamond products specially developed for applications in metal, electroplated, resin and vitrified bond tools. PremaDia PDA999 is a highly crystalline synthetic diamond product with a high impact strength, thermal stability and uniform particle shape. It is designed to withstand the high dynamic loads encountered in very demanding metal bond applications. Designed for use in high-productivity metal bond grinding applications. PDA989 performs particularly well in applications requiring a high strength abrasive. It is a blocky,...

PREMADIA FOR MULTIPLE APPLICAT IONS PRODUCT PDA446 has a sharp particle shape to ensure good free-cutting characteristics. The average particle strength is controlled to make it suitable for use in metal bond tools where low abrasive strength is required. This degree of friability also makes it suitable in metal clad form as PDA446NX55 for use in some resin bond applications. PDA433 is a friable abrasive suitable for use in a wide range of standard resin bond applications and is offered with the full range of metal claddings. It is recommended for use in general purpose applications and...

ME TAL CL AD ABR ASI V E FOR RESIN BONDS Resin bond diamond tools are used extensively in the machining of cemented carbides and are finding increasing popularity in applications such as stone polishing and the grinding of advanced engineering ceramics. The metal claddings applied to diamond particles have been found to provide the distinct advantages in resin bond tools of improving heat dissipation and particle retention in the bond. The metal claddings applied to PremaDia products have been specifically developed for tools using resin bonds, ranging from the widely used phenolic resins...

PROPERT IES OF PREMADIA E-T R E AT MEN T OF SY N T HE T IC DI A MOND PR ODUC T S PHYSICAL PROPERTIES PRODUCT A slightly roughened surface on the diamond particle aids retention of the abrasive in the bond system. The special E-treatment further enhances the plating characteristics of the particle and, in addition, can improve its retention in this way. All PremaDia synthetic diamond products with a Particle Structure Indicator value of 7 or higher are available with E-treatment, e.g. PremaDia PDA989E. CLADDING WEIGHT (%) The sizing of all standard PremaDia products is carried out under...
