In former days hard and brittle materials, as i. e. hard metals and cermets, were generally processed with rubber or resinoid bonded diamond grinding wheels where as result used cutting velocities (vc=18-22 m/s) and material removal rates (Q'w = 0.5-2.0 mm/s) had been very low. Aqueous solutions or emulsions had been used as coolants.

29/01/2018Thru-feed grinding is a type of centerless grinding. During this process, the workpiece passes through the machine itself. It proves to be an effective option for single-size diameter parts anywhere from a small dowel pin to a 16" shaft. We're able to automate our thru-feed operations via vibratory bowls, which allow for continuous feeding.

The effects of mechanical grinding on morphology and electrochemical performance of graphite and soft carbon powders with respect to lithium insertion were studied. The morphology of the milled graphitic powders was found to depend strongly upon the nature of the interactions (e.g., impact or shear) generated by the two kinds of mixer mills used. For the same milling time,
