Dongguan Qida Hardware Machinery Co., Ltd. Precision Medical Device Parts Processing Project Case

       Dongguan Qida Hardware Machinery Co., Ltd. was established in 2008, headquartered in Dongguan, with a branch factory, Changsha Daqi Intelligent Equipment Co., Ltd., located in Hunan, mainly providing intelligent manufacturing solutions for precision hardware components to domestic and foreign customers.

In the field of medical devices, its company has undertaken a processing project for high-end medical equipment precision components. The client for this project is a well-known medical device manufacturer that requires a batch of high-precision medical endoscope lens components, with extremely high demands on the precision and quality of the components. For example, the dimensional tolerance of the lens connection areas must be controlled within ±0.01mm, and the surface roughness must reach below Ra0.2μm. Any slight error may affect the imaging effectiveness and safety of the endoscope.

        After receiving the project, Qida Company quickly formed a special team composed of mid-to-senior level technical personnel. In response to the complex structure and high precision requirements of the accessory, team members first conducted in-depth technical discussions and process analyses, ultimately deciding on a processing plan that utilized a high-precision five-axis CNC machining center. During the processing, to ensure the surface quality of the lens accessory, the team adopted micro-lubrication cutting technology, which effectively reduced cutting heat and tool wear, while also improving surface finish.

       In terms of quality management, the company strictly controls every aspect according to the ISO 9001:2015 quality management system. From the inspection and storage of raw materials to the measurement of dimensional accuracy and surface quality control during the processing, and finally to the final inspection of finished products, there are professional quality inspection personnel to ensure strict compliance. For example, after completing each processing step, a coordinate measuring machine is used to measure the key dimensions of the parts. If any dimensional deviation is found to exceed the allowable range, immediate adjustments and corrections are made.

      Through the efforts of the team, the company successfully completed the processing tasks for this batch of precision medical device accessories. The product's precision and surface quality met the client's strict requirements, with dimensional tolerances for the lens connection controlled within ±0.008mm and a surface roughness of Ra0.15μm. The successful delivery of this project not only provided strong assurance for the client's medical equipment to smoothly enter the market but also further enhanced the company's reputation and credibility in the precision hardware processing industry. Subsequently, the client established a long-term and stable cooperative relationship with the company, leading to deeper collaboration on more medical device accessory processing projects.
