On electric grinders such as the Kitchen Aid meat grinding attachment, be sure to use the coarse grinding plate first and then regrind the meat a second time with the fine grinding plate. This is much faster than stopping to remove sinew all the time and sometimes the coarser ground meat is fine if the cut of meat you are grinding is tender anyway.
The grinding force ratio or friction coefficient indicates the combination of abrasive cutting and friction between the wear flats and workpiece. In CAMQL grinding, higher lubrication of the wear flat area of grains results to lower frictional shear stress in the contact zone and consequently lower tangential forces in grinding process.

The process is continued with finer and finer grinding and polishing abrasives. The final layer is removed chemically by etching with an acid or some suitable agent. During fine grinding the specimen is held so that the new finer scratches are introduced at approximately right angles, to those resulting from its previous rough grinding operations.
