Our stainless steel CNC turning process begins with selecting premium-grade stainless steel bars such as SS304, SS316, or SS416. The material is cut to length and precisely turned using advanced CNC lathes. Our technicians control critical dimensions, surface geometry, and any required features like threading, grooving, or drilling.
However, the true value of a high-end stainless steel component isn’t just in its shape — it’s in the final surface finish, which is where our expert polishing process comes into play.
While functional performance is essential in medical components, the surface finish is equally critical. Polished stainless steel parts are preferred in medical environments for several reasons:
In medical settings, parts must withstand harsh environments. A polished surface eliminates microscopic surface defects that can serve as entry points for corrosion. A smooth, polished finish improves the part’s resistance to moisture accumulation, ensuring longevity even in high-humidity or sterile environments.
A polished finish elevates the visual appeal of stainless steel components, providing a sleek, high-end look. This is particularly important for parts that are visible in medical equipment or surgical tools, where both functionality and aesthetics play a role in patient care and user confidence.
Medical devices and equipment often involve dynamic assemblies or fluid systems where friction and wear are concerns. Polished stainless steel minimizes these issues by reducing surface resistance, which in turn decreases the buildup of particulates. This ensures the longevity of the components and reduces the risk of malfunctions or contamination in critical medical applications.
Sterility is paramount in the medical industry. Polished stainless steel surfaces are smooth and non-porous, making them less likely to harbor contaminants. This is crucial for medical parts that must be cleaned frequently and thoroughly, such as surgical instruments, diagnostic equipment, and implants.
At [Your Company Name], we follow a detailed multi-step polishing process to achieve the highest surface finish quality. Every step is tailored to the specific geometry and application requirements of the medical components we manufacture.
The first step involves a thorough inspection of the turned surface, followed by the removal of any burrs or machining marks through abrasive brushing or buffing. This ensures that the surface is free of imperfections before the polishing process begins.
Using a variety of specialized polishing tools and compounds, we refine the surface roughness to meet industry-standard Ra values or customized specifications. This step ensures that each part meets the stringent surface finish requirements for medical applications.
Depending on your application needs, we offer different finish options:
Satin/Matte Finish: Ideal for industrial or low-glare environments.
Mirror Polish: Perfect for high-visibility or aesthetic-sensitive medical devices and components.
After polishing, every part undergoes ultrasonic or chemical cleaning to ensure it is free from contaminants. We then conduct a final inspection to verify surface quality, consistency, and cleanliness before packaging.
We understand that every medical application has unique requirements. That’s why we offer customized polishing services, including:
Surface roughness options ranging from Ra 0.4 to 3.2 μm
Passivation and electropolishing services for enhanced corrosion resistance
Polishing for both internal and external features
Full traceability and surface roughness reports available upon request
