The main components are phenolic resins. Resin bonds flow at approx. 180-200 ° C. In other words, they polymerize from powder to liquid. In contrast to the ceramic bond, synthetic resin bonds are much more susceptible to solutions, oils, polluted water and temperature influences.
They are more elastic than ceramic bonds, yet very tough and strong, and also have good thermal conductivity, which means that frictional heat can be removed more quickly from the cutting zone, which means that the grinding behavior is cooler, especially for dry grinding tasks.
Due to its chemical properties and hardness, it is particularly suitable for processing: hard metal, hard metal – steel combinations, sprayed and welded alloys, oxide ceramics, porcelain, earthenware, silicon, ferrite, semiconductor materials, graphite, electric carbon, natural and artificial stone, glass fiber reinforced plastics , Thermosets, glass, quartz, refractories, polycrystalline diamond (PCD) and polycrystalline CBN (PKB). The selection of the suitable diamond type is made from a very wide range of synthetic and natural, metal-coated, vapor-coated or uncoated, regularly or irregularly shaped grains.
It is manufactured synthetically, is resistant to high temperatures and is mainly used to machine the following materials: tempered steels, cast iron, spring steels, case hardening steels, high alloy steels, hot and cold work steels, high speed steels, ball bearing steels and stellites. Similar to diamond, CBN can also choose from a wide range of types with different properties.
The grain size used largely determines the grinding performance and the surface quality achieved. With constant carat content, the number of grain tips on the surface of the base increases with finer grain, subjectively the disc becomes denser, harder and less abrasive. In order to create chip spaces on the abrasive coating, it is therefore necessary to adjust the concentration to the grain size in order to prevent the grain from being packed too tightly.
