Why CNC Turning is Crucial for Medical Device Manufacturing?
CNC turning has a number of benefits in terms of manufacturing medical CNC turning equipment particularly in the production of devices that need high precision and reliability. Let’s discuss the factors that make cnc turning important in the medical field.
Précision et exactitude
Medical equipment requires parts with very tight tolerances, and sometimes, as tight as ±0.0001 inches. CNC turning offers the utmost precision in that a component will fit and work perfectly as required in the body or a medical apparatus.
Efficacité et rapidité
Although accuracy is essential, time is also an important aspect of the medical field. CNC turning is able to make parts without losing quality. This renders it suitable to small-batch and large-volume production operations of medical parts, minimising lead times.
Versatility of Materials
Titanium, stainless steel, medical grade plastics and ceramics are some of the high-strength and biocompatible materials that are used in medical CNC turning devices. There are many types of materials that can be used in CNC turning, which guarantees the final product meets regulatory standards and can be used in the desired Medical CNC turning application.
Cohérence et répétabilité
Fabrication de dispositifs médicaux requires consistency because every single part of the devices should be satisfied with strict quality standards. CNC turning presents superior repeatability, i.e. the first piece will be the same as the last piece which is important in medical devices.
CNC Turning vs. CNC Milling in Medical Device Manufacturing
Although both Fraisage CNC and CNC turning are part of the production process of medical CNC turning devices, the purposes they are used in are different. Here’s how they compare:
| Fonctionnalité | Tournage CNC | Fraisage CNC |
| Ideal for | Producing cylindrical or rotational parts | Producing flat, complex, and 3D-shaped parts |
| Utilisation des matériaux | Best for materials like metal, plastics | Suitable for a wider range, including aluminum, titanium, and plastics |
| Vitesse | Faster for high-volume production of cylindrical parts | Slower due to its ability to create more intricate designs |
| Précision | High precision, especially for rotational parts | Excellent precision, ideal for complex geometries |
| Common Medical Uses | Needles, bone screws, implants | Surgical tools, medical housing, prosthetics |
Top Tips for Designing CNC Turning Medical Parts
