Diamond tools - Import export

Beside the non-dressable CBN grinding tools, dressable grinding tools of leading manufacturers can be used on our machines, too. Vitrified bond aluminium oxide tools are dominant. Sintered aluminium oxide is preferred as the grinding tool for grinding of steel due to its resilience and grinding capability. Gray cast-iron can also be processed with normal aluminium oxide. The profiling of the grinding tools takes place via a machine-integrated CNC dressing unit. A diamond-plated, rotating dressing tool profiles the wheel in accordance with the respective gear parameters. The grinding tool is conditioned specifically for rough or finish grinding by selecting respective technological dressing parameters. Form consistency and cutting capacity of the grinding wheel is assured by repeated dressings, dependent on pre-defined stock removal rates. The automatic balancing produces smoother turning for larger grinding tools, and consequently, high gear quality. dressable CBN tools Single-layere

ZINNER PKD or highly positively polished cutting inserts are used for machining aluminium and copper. Glass-fibre reinforced materials are machined with PKD or coated PKD tools. Diamond tools are ideally suited for the high gloss turning of non-ferrous metals.

CBN (cubic boron nitride) is the next hardest material after diamonds. When properly used, tools made from CBN exhibit considerably less wear than other materials. Cutting inserts or even VHM tools can be equipped with CBN. Technical application: Hardened tool steels with hardnesses greater than 55 HRC or high speed steels (HSS) can be machined without problems using CBN. Case hardened steels and chilled cast iron can also be machined with CBN. Non-ferrous metals are totally unsuitable for CBN; diamond tools are needed for these.
