Description
Technical Field
The utility model relates to a combination formula emery wheel for cutting into grinding.
Background
In grinding of workpieces, grinding wheels having a large aspect ratio are often used, and such grinding wheels are generally called high-thickness grinding wheels or high-thickness grinding block grinding wheels. The high-thickness grinding wheel has two grinding modes when processing a workpiece, namely a through grinding mode and an in-cutting grinding mode, wherein the through grinding mode refers to that the grinding wheel synchronously performs axial and radial feeding relative to the workpiece in the grinding process, and the in-cutting grinding mode refers to that the grinding wheel only performs radial feeding relative to the workpiece in the grinding process.
Because the axial size of the grinding wheel is large, if the traditional integral pressing forming process is adopted, even if the measures of double-sided pressure application and fractional feeding and tamping are adopted, the problems of large hardness at two ends of the grinding wheel, small hardness in the middle of the grinding wheel or inconsistent uniformity of axial tissues caused by pressure loss can not be effectively solved, although the grinding wheel can meet the processing quality requirement in the through grinding, for the cut-in grinding, the consistent processing can not be carried out on all parts of the workpiece due to inconsistent axial consumption of the grinding wheel along the cut-in grinding, and the processing quality of the workpiece is directly influenced.
Aiming at the problems, the prior art can adopt a combined mode to produce the high-thickness grinding wheel, namely, a plurality of single grinding wheels with relatively small axial dimension and consistent hardness are produced, the axial end face of each single grinding wheel is vertical to the axis, and then the plurality of single grinding wheels are fixedly combined into the high-thickness grinding wheel with the required axial dimension by a parallel stacking method. The technical problem that high-thickness grinding wheels are different in axial hardness can be effectively solved through the production mode, the phenomenon that the grinding wheels are inconsistent in axial consumption in the working process is avoided, however, when the grinding wheels are cut in, due to the fact that fit gaps exist between two adjacent single axial small-size grinding wheels, an annular grinding trace which cannot be eliminated can be left on a workpiece, and therefore the machining quality of the workpiece is low.
