One is a polynismous planar grinder, with a vacuum cleaner, dust and iron filings that occur when grinding the workpiece, grinding such a workpiece is the unmatched workpiece, thickness and width are very large, in oneIt is a water grinding, a flushing apparatus, which is deformed by the parts, and the surface heat is flushed, so that the workpiece surface heat is eliminated, so that the finish of the workpiece ensures small workpiece deformation coefficient, so that the workpieceSolid, there are several special grinding, slope grinding, trimming grinding, grinding workpiece, circular grinding, assignee grinding machine, using end faces around the grinding wheel, roll workpiece to grindR angle grinding, also the R viewpoint that complies with the grinding wheel and the workpiece, and eating the knife slowly.
