The terms "first", "second", etc. in the specification and claims of the present invention or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0029] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 3 In some embodiments, the present invention provides a method for processing a sapphire blade head for a hair clipper, comprising the steps of:

[0032] S1. Selecting a block sapphire raw material, and cutting the block sapphire raw material into sapphire rough embryos by wire cutting equipment;

[0033] S2, grinding the rough blank into a sapphire blank of a preset size, and polishing the surface of the sapphire blank;

[0034] S3, placing the polished sapphire blank into a preset fixture and fixing it, advancing the sapphire blank in the direction of the teeth to be ground by a preset rough grinding wheel and grinding out a first tooth shape, advancing the sapphire blank in the direction of the teeth to be ground by a preset fine grinding wheel and fine grinding into a second tooth shape, advancing the sapphire blank in the direction of the teeth to be ground by a preset fine grinding wheel and fine grinding into a third tooth shape;

[0035] S4, polishing the shape of the third cutter teeth to form a blank for the sapphire cutter teeth;

[0036] S5. Grind the sapphire blade blank to the size that meets the preset hair clipper head, and then use a CNC machine tool to make grooves on the bottom surface and make fixing holes to form a sapphire blade head for the hair clipper.

[0037] In step S1, the selected block sapphire raw material only needs to be able to be cut into a blank larger than 42 mm in length, 22 mm in width, and 2.5 mm in height.

[0038] In step S2, the rough blank is ground into a sapphire blank of a preset size, that is, a sapphire blank of 42 mm in length, 22 mm in width, and 2.5 mm in height, and then the sapphire blank is installed in a fixture of a polishing machine, and is first rough-polished and then fine-polished to make the surface of the sapphire blank bright. The polishing mesh can be gradually increased from 400 mesh to 2000 mesh. For example, first polish with a 400 mesh polishing sheet, and then gradually increase to 800 mesh, 1200 mesh, 1600 mesh to 2000 mesh.

[0039] In step S3, the polished sapphire blank is placed in a preset fixture and fixed. The preset fixture is as follows: Figure 2 As shown, the sapphire blank is placed in the preset fixture as shown in Figure 3As shown, it is worth mentioning that the preset fixture is in the shape of a right-angled triangular prism as a whole, wherein the side wall where the hypotenuse of the right-angled triangular prism is located is provided with a U-shaped groove with an opening facing one side, and the bottom of the U-shaped groove is provided with a plurality of holes penetrating the right-angled triangular prism. By placing the sapphire blank on the preset fixture, the above-mentioned holes are connected to the negative pressure equipment, and fixed to the preset fixture by negative pressure adsorption. This fixing method is extremely simple and easy to operate, and can be manually operated or adapted to automated processing. The preset rough grinding wheel is used to advance the sapphire blank in the direction of the teeth to be ground and the first tooth shape is ground. At this time, a 300-500 grinding wheel is used for tooth grinding, such as a 400 grinding wheel; the preset fine grinding wheel is used to advance the first tooth shape and finely grind it into the second tooth shape. At this time, a 600-800 grinding wheel is used for tooth grinding, such as an 800 grinding wheel; the preset fine grinding wheel is used to advance the second tooth shape and finely grind it into the third tooth shape; at this time, a 1000-1200 grinding wheel is used for tooth grinding, such as a 1200 grinding wheel. After three steps of tooth grinding, the teeth can be sharp enough to cut hair with a driving force of 0.15-0.2N. It is worth mentioning that the preset rough grinding wheel, the preset fine grinding wheel and the preset fine grinding wheel are all in the shape of a corrugated tube, such as Figure 4 As shown, the feed rate during the three-step grinding process is controlled at 0.02-0.05mm / time to prevent the embryo from collapsing.

[0040] In step S4, the third tooth shape is polished to form a sapphire tooth blank. The polishing can be done by polishing the frosted bevel of the tooth with a polishing device.

[0041] In step S5, the sapphire blade blank is finely ground to meet the preset external dimensions of the hair clipper head, that is, after fine grinding, it is consistent with the external dimensions of the ordinary stainless steel blade head or alloy blade head, adapted to the conventional hair clipper, and then the bottom surface is grooved and the fixing holes are made by a CNC machine tool to form a sapphire blade head for the hair clipper, which has the same external dimensions as the ordinary stainless steel blade head or alloy blade head, such as Figure 5 shown.

[0042] Finally, additional steps can be added to clean and inspect the sapphire blade head of the hair clipper to ensure the yield rate.

[0043] The above method has a simple manufacturing process and a high yield rate, and the produced blade head has a high hardness, with a Mohs hardness rating of 9, while the Mohs hardness rating of general stainless steel is only 5.5. In comparison, the sapphire blade head is extremely durable.

[0044] Obviously, the embodiments described above are only some embodiments of the present invention, rather than all embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
