2002101 · The solution of the classic problem of stress in a rotating elastic disk or cylinder, as solved in standard texts on elasticity theory, has two features: dynamical equations are used that are valid only in an inertial frame of reference, and quadratic terms are dropped in displacement gradient in the definition of the strain. I show that, in an …

2022215 · A theoretical model of warping deformation in self-rotating grinding of YAG wafers was developed based on the cutting depth and grinding force. The influence of subsurface damage and residual stress on warping deformation was analyzed based on the theoretical model and finite element simulation. Self-rotating grinding tests of YAG wafers …

201511 · A grinding machine is a machine for material removal with geometrically non-defined, bonded cutting edges, where the relative movement between tool and workpiece is rotational or linear. The machine further must provide relative feed and positioning movements between tool and workpiece. The movements between tool support (spindle) …

Grinding and Polishing Guide Grinding should commence with the finest grit size that will establish an initially flat surface and remove the effects of sectioning within a few minutes. An abrasive grit size of 180-240 [P180-P280] is coarse enough to use on specimen surfaces sectioned by an abrasive wheel. Hack-sawed, bandsawed, or other rough surfaces …

202211 · Abstract Unlike most double-disc grinding processes, which use forced workpiece rotation, some double-disc processes rely on workpiece self-rotation driven by non-uniform shear forces resulting from partial wheel-workpiece coverage. This self-rotation is poorly understood, with workpiece angular frequency remaining unknown despite its …

The grinding-polishing machine is a double-disc desktop, operated by two people simultaneously, applicable to pre-grinding, grinding and polishing of metallographic sample. The machine regulates its speed by a frequency changer, with a speed of 50-1000rpm, thus widening its application. The machine is an indispensable equipment in making the ...

2023328 · The two wheels rotate at different speeds. The relative speed of the two wheels provides the grinding action and the speed of rotation determines how much material is removed from the workpiece. Centerless grinding processes are often automated to enable a higher level of precision machining.
