ABRASIVE COMPOUNDS

BKM Abrasive Flow Machining process uses a compound laden with abrasive grain as the cutting tool. Abrasive Flow compounds can be designed for specific applications and to control material removal precisely.

BKM Abrasive Flow compound has two principal components, a base and abrasive grain. The base is a highly resilient organic polymer blended with special lubricating diluents. The base is manufactured into varying viscosities from high viscosity, which is stiff, to a low viscosity, which is less stiff.

The abrasive grain component of the compound is composed of many different grain types and sizes. Some commonly used abrasive grains are aluminum oxide, boron carbide and silicon carbide. These abrasive grains can be used for material removal, processing especially hard materials, and polishing. All of these abrasive grains offer long life, durability and are economical.

After a compound has had extensive use lubricants are lost from the compound due to gradual transfer to the processed workpieces. In addition the abrasive grain will break down or lose its effectiveness. It is possible to recondition the compound by using a reconditioning compound which will extend the life of the compound. When reconditioning your abrasive flow compound a measured amount of abrasive grain and lubricant-rich base is added to restore the working efficiency of the compound. The reconditioning compound is added directly the Abrasive Flow Machine, a mixing cycle needs to be run in order to ensure proper mixing of the used compound and the reconditioning compound.
