Description

Technical Field

[0001] The utility model relates to the technical field of nickel-titanium alloy wire processing, in particular to a nickel-titanium alloy wire polishing device. Background Art

[0002] In the field of nickel-titanium alloy wire processing technology, polishing process plays a vital role. Nickel-titanium alloy wire has been widely used in many fields such as medicine, aerospace, electronics and machinery due to its good biocompatibility, superelasticity and shape memory effect. However, its polishing process faces many challenges.

[0003] At present, the polishing of nickel-titanium alloy wire mostly relies on manual operation. Although this method can meet basic polishing needs to a certain extent, its efficiency is extremely low, and the polishing quality is often affected by human factors, making it difficult to maintain consistency. In addition, manual polishing also has problems such as high labor intensity and poor working environment, which is not conducive to improving production efficiency and worker health. With the development of automation technology, some automatic polishing devices have been introduced into the nickel-titanium alloy wire processing field in order to improve polishing efficiency and quality. However, these automatic polishing devices are often unable to adapt to nickel-titanium alloy wires of different thicknesses in actual applications, and cannot meet the polishing needs of diversified products. Therefore, a polishing device for nickel-titanium alloy wire is proposed. Utility Model Content
