Titanium is renowned in the manufacturing world for its exceptional strengthtoweight ratio, outstanding corrosion resistance, and excellent biocompatibility. These properties make it the material of choice for demanding industries like aerospace, medical implants, and highperformance automotive. However, these very advantages also present significant machining challenges. Successfully CNC machining titanium requires a specialized approach, and partnering with an expert machine shop is critical to achieving costeffective and highquality results.

Instead, it concentrates at the cutting tool edge, leading to rapid tool wear and potential failure. Furthermore, titanium's galling tendency can cause it to weld to the cutting tool, resulting in poor surface finish and tool damage. Its high strength also demands significant machining power and rigidity from the CNC equipment.
To overcome these challenges, a successful strategy involves several key factors:
1. Tooling Selection: Using sharp, premiumgrade carbide tools with specialized coatings like PVD (Physical Vapor Deposition) is essential. These coatings reduce friction and heat generation. Geometry is also critical; a positive rake angle helps shear the material cleanly.
2. Optimized Parameters: Conservative cutting speeds with higher feed rates are generally more effective than aggressive speeds. This approach helps control heat by ensuring the chip carries away the majority of the thermal energy. A consistent and ample supply of highpressure coolant is nonnegotiable to cool the tool and flush chips away.
3. Machine Rigidity: The machining process imposes high cutting forces. Therefore, a very rigid CNC machine, sturdy workholding, and a short tool overhang are mandatory to minimize vibration (chatter), which can ruin surface finish and damage tools.
