The larger grain load, the more shallow abrasive cutting depth

Experiments show that the work twice as fast, wheel blockage increased threefold. Because the higher the speed the workpiece, abrasive load greater, the more shallow depth of cut grain, chip  abrasive grinding  area becomes small, when the grinding thickness increases, and glazing increase, increase the grinding wheel layer extrusion of the workpiece equivalent wheel features harden, thus exacerbate wheel clogged.
In the grinding way, all wheel and workpiece increases the contact area of the grinding wheel will  ubic boron nitride . This is because the contact area of the wheel and the workpiece, the cutting edge of abrasive wear scar at once on the same scratch the workpiece on the grinding wheel layer enhanced intensified cooling fluid into the grinding zone and difficult, grinding more heat, high temperature , to create  cutting tools  for the blockage, easy to produce chemical adhesion clogging and blockage embedding. End mill grinding than weeks as easy to plug, horizontal than vertical plunge grinding grinding congested.
