Problems solved by technology
[0002]According to market research and patent retrieval, high-gloss chamfering processing of stainless steel and other products, especially the fingerprint recognition keys in mobile phones requires a very high smooth surface. After the chamfering knife is processed, it is easy to produce defects such as sharp edges, burrs, different colors, streaks and vibration lines, and the finish is low, and the yield is not high, resulting in the need to increase the manual deburring process in the later stage, resulting in low production efficiency and poor quality. high return rate

The invention discloses a specular rose reamer for processing fingerprint identification keys. The specular rose reamer comprises a reamer handle and a blade portion formed on one end surface of the reamer handle, wherein the blade portion extends in the direction of a rotating shaft to form a bottom surface. The specular rose reamer further comprises a main blade used for cutting a conical specular inner surface, the angle formed between the main blade and the rotating shaft is 74.75 degrees, and the tolerance is + / -0.25 degree. The back angle blade width is 0.13mm, and the tolerance is + / - 0.02mm. The specular rose reamer can produce the specular surfaces in one time; is firm in structure, durable and good in work stability and safety, and greatly improves the production efficiency. Therefore, the specular rose reamer has excellent technical performance and economical efficiency.
Description
[0001] 【Technical field】 [0002] The invention relates to a high-gloss chamfering knife used for processing fingerprint identification keys. 【Background technique】 [0003] According to market research and patent retrieval, high-gloss chamfering of stainless steel and other products, especially the fingerprint recognition keys in mobile phones, requires a very high smooth surface. The existing chamfering knives are prone to sharp edges, burrs, and discoloration after processing. , stripes and vibration patterns, etc., and the finish is low, and the yield rate is not high, which leads to the need to increase the manual deburring process in the later stage, low production efficiency, poor quality, and high return rate. In order to overcome the above defects, we have developed a high-gloss chamfering knife for processing fingerprint identification keys. 【Content of invention】 [0004] The technical problem to be solved by the purpose of the present invention is to provide a ...
