'METAL BOND' MICRON DIAMOND POWDERS
Syndia® - 'Metal Bond' type monocrystalline micron diamond powder
The SYP polishing size range contains very blocky particles, yet retaining sharp cutting edges. SYP includes all medium and fine precision micron sizes. Through its very blocky particle shape, it withstands the high workloads resulting from any lapping and polishing applications.
SYP Datasheet
The SYG grinding range has been specially developed for metallic, electroplated and vitrified bonds. Its particle shape lies in a defined tolerance range between blocky and irregular. SYG includes a wide choice of micron sizes up to 70-120 microns, which matches the 230/270 mesh size. Its more aggressive particle shape guarantees excellent abrasive performance with good particle retention.
SYG Datasheet
The SYS ‘Sharpcut’ range is of a slightly more friable nature, with even sharper particles to suit the most difficult grinding applications, particularly when the workpiece material or working conditions demand lowest cutting forces. SYS is suitable for all bond types and is available in a large number of sizes between 1 and 50 microns.
SYS Datasheet
All micron diamond powders are produced from crushed raw material. SYT however is an uncrushed 'metal bond' type micron diamond powder. The particles are directly synthesized, with particle characteristics similar to mesh products. SYT is available in the coarsest micron sizes, as a direct extension from the finest mesh size products. It is used in some very sensitive applications, for its higher impact resistance and reduced chipping.
