Abstract
The utility model relates to the technical field of grinding equipment, in particular to a pyramid grinding disc. The pyramid grinding disc comprises a cylindrical base body, and at least one bottom surface of the base body is connected with a grinding layer comprising a grinding bottom layer and a plurality of grinding blades. The grinding bottom layer and the grinding blades are formed integrally. The grinding bottom layer is positioned between the base body and the grinding blades. The grinding blades are annular protrusions taking the circle center of the base body as the center. The grinding blades are connected with the grinding bottom layer through roots. The gaps between adjacent grinding blades are the same. During processing, new ends of the grinding blades are formed on exposed portions after the ends of the grinding blades are abraded so as to grind workpieces, and the ends of the grinding blades are allowed to keep certain roughness to continue grinding. Therefore, the pyramid grinding disc can perform grinding at a high cutting rate for a long time, an operator applies almost the same pressure condition in the whole grinding process to process stably and continuously, processing is facilitated, and a good, uniform and accurate grinding effect is easy to achieve.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model being described in further detail, is not that practical range of the present utility model is limited to this.
As shown in Figure 1, the pyramid abrasive disk of present embodiment, it comprises columniform matrix 1, at least one bottom surface of described matrix 1 is connected with grinding layer, during use, matrix 1 is connected with milling apparatus, grinding layer is towards workpiece to be processed, milling apparatus drives matrix 1 and rotates, thereby by grinding layer workpiece is ground, and is holistic disk with respect to the pyramid abrasive disk of prior art, the utility model is with pyramid abrasive disk separated into two parts matrix 1, grinding layer two parts, after using a period of time, the grinding layer after the wearing and tearing can be replaced, and matrix 1 can reuse.And, described grinding layer comprises grinding bottom 2, several grind sword 3, described grinding bottom 2 and described grinding sword 3 are one-body molded, described grinding bottom 2 is positioned at described matrix 1, grind between the sword 3, it is identical with the material that grinds sword 3 to grind bottom 2, but its shape difference, grinding bottom 2 is writing board shape, mainly play a supportive role, mainly play abrasive actions and grind sword 3, described grinding sword 3 is the annular protrusion at center for the center of circle with matrix 1, described grinding sword 3 is connected with described grinding bottom 2 by root, the spacing of described adjacent grinding sword 3 equates, grinding the cross-sectional width of sword 3 from root to the end diminishes gradually, during use, after grinding the end wear of sword 3, the part of exposing forms new end, can grind workpiece, the chip of grinding sword 3 and workpiece falls into the groove between the adjacent grinding sword 3, and then discharge with lapping liquid, thereby make the end of grinding sword 3 keep certain roughness, can proceed to grind, therefore, pyramid abrasive disk of the present utility model can grind and keeps the long period with high stock removal rate, and the operator applies pressure condition much at one in the overall process of grinding, can carry out stably, continuous processing, made things convenient for processing, and the correct grinding effect of the unanimity that obtains easily.
