The temporal dynamics of anthropogenic impacts on the Pchelina Reservoir is assessed based on chemical element analysis of three sediment cores at a depth of about 100–130 cm below the surface water. The 137Cs activity is measured to identify the layers corresponding to the 1986 Chernobyl accident. The obtained dating of sediment cores gives …
The condition of your chips is also important information. When grinding, the workpiece is ground by the cutting edges of abrasive grains, discharging fine chips. The shedding, glazing, etc. of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain. This phenomenon occurs from a constant timing.
