Both the abrasive sheet layer and the slice layer are made of lossy material. When the cutting and grinding machine is used, the cutting and grinding piece is installed on the cutting machine until the slice layer of the cutting and grinding piece is worn to the slice layer, the cutting and grinding piece is taken down from the cutting machine and is installed on the large-angle grinder for grinding, and when the slice layer is worn to a certain degree, the cutting and grinding piece is installed on the small-angle grinder for continuous use until the cutting and grinding machine is used up. Compared with the conventional cutting machine slice layer, the slice layer has the bright point that the slice layer is zero residual, 100% of materials are applied, and the residual quantity of the conventional slice is about 20%.

Description

Cutting and grinding piece Technical Field The invention relates to the technical field of tool cutting products, in particular to a cutting and grinding sheet. Background In the current state of the art in modern industrial manufacturing, the chips are typically mounted on a cutting machine. Such cutting machines have a critical role in industrial production, in which the slicing plays a critical role, mainly for cutting metal or plastic products. The refiner plate layer is often mounted above the angle grinder. Angle grinders are a common and practical industrial tool, with the abrasive sheet layer being used to polish metal by the power of the angle grinder. The rough metal surface can be gradually smoothed by continuously polishing, so that the requirements of industrial production on the flatness and the smoothness of the metal surface are met. In the prior art case, the slice is actually only that part of the outermost circle which is actually used for the cutting operation. The structure of the sliced layer is more specific, and the middle and inner ring parts are all actually substrates. During the continuous cutting operation of the slicing layer, the outermost ring will continuously rub against the cut material, and gradually wear over time. When the outermost ring of the slice layer is worn to almost the end and effective cutting work cannot be continued, the whole slice layer is directly discarded according to the existing processing mode. However, this treatment has a great disadvantage, since the portion of the substrate that is discarded actually has a certain value, which results in a large amount of material being wasted. Similarly, the lapping layers used in the angle grinder have the same problems. The abrasive disc layer is worn out continuously in the long-time polishing process, and after a certain degree is reached, the whole abrasive disc layer can be abandoned, and the great waste of materials is also caused. Disclosure of utility model To slicing layer or abrasive disc layer utilization ratio among the prior art not high, there is extravagant problem of a large amount of materials, this scheme has proposed a slicing and abrasive disc, makes abrasive disc layer replace slicing layer middle ring layer substrate through making slicing layer abrasive disc layer integrated into one piece, solves prior art problem. In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: the application provides a cutting and grinding sheet, which is disc-shaped and comprises The connecting layer is provided with a mounting hole at the center, and the mounting hole is connected to the rotating shaft of the cutting machine or the angle grinder; The abrasive disc layer is connected to the periphery of the connecting layer and made of a loss material, and the outer diameter of the abrasive disc layer gradually decreases to the periphery of the connecting layer along with the increase of sharpening time; and the slicing layer is integrally connected to the periphery of the abrasive disc layer and is made of a loss material, and the outer diameter of the slicing layer gradually decreases to the periphery of the abrasive disc layer along with the increase of cutting time. The connecting layer of the cutting blade is positioned at the innermost layer of the whole cutting blade, the blade layer is connected to the periphery of the connecting layer and positioned at the middle ring layer of the whole cutting blade, and the cutting blade layer is positioned at the periphery of the blade layer and positioned at the outermost ring of the whole cutting blade. Both the slice layer and the abrasive sheet layer are made of lossy material. When the angle grinder is used, the cutting and grinding piece is firstly installed on the cutter for use, and the cutting and grinding piece is taken down from the cutter and installed on the angle grinder for continuous use until the slice layer of the cutting and grinding piece is worn to the grinding piece layer. When the blade layer on the angle grinder is worn down to the tie layer, the functional area of the entire cutting blade is worn down. Compared with the traditional cutting machine slice layer, the slice layer provided by the application can replace the middle ring layer area of the slice layer, and the slice layer not only can play a role in supporting the slice layer substrate, but also can be continuously utilized to the connecting layer. Therefore, the utilization rate of the slicing layers can be greatly improved, and the waste of the base material is avoided. In the cutting blade provided by the application, further, when the slicing layer is used, the cutting blade is connected to a cutting machine. The slicing layer can directly use the slicing sheet on the cutting machine, so that the slicing sheet can be manufactured into standard types and is suitable for various cutting machines without specially manufacturing the
