LEMAN cutting wheels The ratio between the volume of tissue characterization abrasive abrasive abrasive

The ratio between the volume of tissue characterization abrasive abrasive abrasive, bond and porosity between the three, often occupied by abrasive abrasive entire volume percentages. metal cut off wheels‍ Coarse abrasive organization into tight, medium and loose three categories. Each category can be subdivided and number, (often expressed as 0 to 14) with the organization number to distinguish. The greater the number of abrasive tissue, the share of the abrasive in the abrasive volume percentage is smaller, the wider the gap between the abrasive particles, said more loose tissue. On the contrary, the smaller the organization number indicates more tightly organized. Loose abrasive organization is not easy when you use passive, less grinding process heat, can reduce heat deformation of the workpiece and burns. Tight organization of abrasive grit easy to fall off, helps maintain abrasive geometry. Abrasives organization to be only in the manufacture of abrasive formula by control, generally do not make the determination.

Because of superhard abrasive abrasive diamond, cubic boron nitride high price, with good abrasion resistance, they are manufactured using ordinary abrasive abrasive abrasive concrete cutting wheels‍ different, except for super abrasive layer, but also there are the buffer layer and the substrate. Super abrasive layer is a part of the cutting action, the super abrasive grains and bonding agent. Bracket base is played in grinding of metal, bakelite or ceramic materials. For connecting the substrate and the buffer layer of super-hard abrasive layer consisting of a binding agent and, sometimes, may be omitted. The binding agents are used resin, metal, plated metal, and ceramics. Such abrasive characteristics marked with ordinary abrasive abrasive much the same, but not marked and labeled abrasive tissue concentrations. Characterization of the abrasive concentration of the inner layer of super abrasive grains per unit volume of the content of the super abrasive grains, expressed as a percentage. 1 cm superabrasive volume containing 0.88 g (4.4 kt) who called 100% concentration, cutting disc china‍ containing 0.44 g (2.2 kt) are referred to 50% concentration, I analogy.
