Nickel products are commonly used in medical devices, aerospace, and other fields due to their superelasticity, shape memory effect, and excellent biocompatibility. Their delicate and complex structures make traditional processing methods difficult to meet the precision requirements. However, laser cutting, with its high-energy-density beam, instantly melts and vaporizes the material, and uses high-pressure gas to remove slag, makes it an ideal processing method.
In terms of precision, the laser beam spot can reach micron levels, with cutting errors controlled within ±0.01mm, meeting the requirements of high-precision products such as vascular stents and precision instrument parts. During the cutting process, the laser beam does not contact the material, avoiding deformation and surface damage caused by mechanical stress, ensuring the stable performance of nickel products. Furthermore, the laser action time is short, resulting in a minimal heat-affected zone, effectively preventing material hardening and embrittlement, maintaining its superelasticity and shape memory properties.
In actual processing, precise control of laser parameters is required. For example, when cutting thin-walled medical device components, low power and high pulse frequency are recommended. The auxiliary gas selection is tailored to the product's application: medical products often use nitrogen to prevent oxidation, while industrial components can use oxygen to improve cutting efficiency. Furthermore, proper surface cleaning and pretreatment of the material are essential, and cutting speeds are optimized to ensure high-quality output.
