ادامه مطلبMicro grinding is a promising process to produce small scale structures in hard and brittle materials. Just like macro grinding processes, a high number of abrasive grits embedded on the grinding tools, are applied. This high number of grits results in low cutting forces on individuall grits and very small chip thicknesses, thus generating surfaces with a high quality.
ادامه مطلبGrinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
ادامه مطلبTHE HISTORY Blanchard Grinding, also called Rotary Surface Grinding, dates back to 1909 when Henry Spencer developed the process for the Blanchard Machine Company in Cambridge, MA. The basic design of these revolutionary machines has changed little since those days and, indeed, some machines from the early decades of the last century are still in use today.
