No CNC milling is capable of handling micro machining with extremely tight tolerances.

CNC milling can create aerospace parts with tolerance tight as 0.00125 mm

When it comes to titanium parts, especially those used in biomedical applications such as implants and medical devices, biocompatibility is a crucial factor. The most biocompatible surface finishing techniques for titanium include:

Anodizing: This process enhances the natural oxide layer on titanium, improving its corrosion resistance and biocompatibility. Anodized titanium is often used in dental and orthopedic implants due to its excellent tissue compatibility and ability to promote bone osseointegration.

Passivation: In this process, titanium parts are treated to remove surface contaminants and improve corrosion resistance, which is essential for biocompatibility. Passivation forms a protective oxide layer that reduces ion release from the titanium, thereby enhancing its biocompatibility.

Electropolishing: This technique smooths and polishes the titanium surface, reducing the risk of bacterial adhesion and biofilm formation. A smoother surface also minimizes the wear and tear of moving parts, important for implantable devices.

The ASTM standards, while developed in the United States, are indeed used worldwide, especially in industries where international trade is common. Many companies and governments globally adopt ASTM standards for their operations and regulations.

Other widely recognized standards include:

ISO (International Organization for Standardization): A global network of national standards bodies with members from over 160 countries.
EN (European Norm): Standards that are used throughout the European Union.
JIS (Japanese Industrial Standards): Used in Japan and in many international markets for Japanese products.
DIN (Deutsches Institut für Normung): German standards that are highly regarded in engineering and often adopted internationally.
BS (British Standards): Developed by the BSI Group, these are used in the UK and in many places that follow British regulatory models.
These standards ensure that materials, products, processes, and services are fit for their purpose.
