The main components are various sintered bronzes. Steel and carbide bindings are rarely used due to their very low self-sharpening effect. Due to the possibility of alloying with a wide variety of metal fillers, this bond in the high-speed range at cutting speeds> 100m / s can lead to high cutting performance and tool life.
This bond group also enjoys a high level of value in the profile grinding area due to the eroding conditioning (simultaneous profiling and sharpening) that is possible today. The sintering temperature, adjusted to the respective binding properties, fluctuate between 700-800 ° C. Sintered metal bonds are harder than synthetic resin bonds, are more wear-resistant and very good heat conductor. They are mainly used for grinding processes in the production of hard metal, HSS / E, ceramics and glass.
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.
