Preferably, the cross sectional shape of described grinding sword is triangle, and this leg-of-mutton base is for grinding the root of sword.
Perhaps, the cross sectional shape of described grinding sword is trapezoidal, and this trapezoidal bottom is for grinding the root of sword.
Wherein, the middle part of described matrix is provided with the connecting hole of perforation.
Further, described matrix is the copper dish.
Further, described matrix also comprises iron pan or aluminium dish, and described iron pan or aluminium dish be and concentric cylindrical of described copper dish, and a bottom surface of described copper dish is connected with grinding layer, and another bottom surface is connected with described iron pan or aluminium dish.
Described iron pan or aluminium sheet and described copper dish by bonding, welding or bolted one or more be connected.
The invention has the beneficial effects as follows: a kind of pyramid abrasive disk, its grinding layer comprises the grinding bottom, several grind sword, described grinding bottom and described grinding sword are one-body molded, described grinding sword is the annular protrusion centered by the center of circle of matrix, the spacing of described adjacent grinding sword equates, add man-hour, after grinding the end wear of sword, the part of exposing forms new end, can grind workpiece, thereby keep certain roughness so that grind the end of sword, can proceed to grind, therefore, pyramid abrasive disk of the present invention can grind and keeps the long period with high stock removal rate, and the operator applies almost identical pressure condition in the overall process of grinding, can carry out stably, continuous processing, made things convenient for processing, and the consistent correct grinding effect that easily obtains.

The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments, is not practical range of the present invention is limited to this.
Such as Fig. 1, Fig. 2, shown in Figure 3, the pyramid abrasive disk of the 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 present invention is divided into two parts matrix 1 with the pyramid abrasive disk, 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, grind bottom 2 identical with the material that grinds sword 3, but its shape is different, 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 centered by the center of circle of 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 keep certain roughness so that grind the end of sword 3, can proceed to grind, therefore, pyramid abrasive disk of the present invention can grind and keeps the long period with high stock removal rate, and the operator applies almost identical pressure condition in the overall process of grinding, can carry out stably, continuous processing, made things convenient for processing, and the consistent correct grinding effect that easily obtains.
