Titanium CNC Machining Services

We start with a solid Ti-6Al-4V (Grade 5) billet. The first step is face milling to establish perfectly flat datum surfaces for subsequent multi-axis setups. Due to titanium's poor thermal conductivity, we use specialized carbide face mills with optimized cutting parameters (moderate speeds with increased feed per tooth) and high-pressure coolant to prevent heat build-up and warping from the start.

Removing bulk material to shape the T-profile. As seen in the image, we maintain a highly stable tool path to ensure uniform stock removal. We utilize highly rigid CNC machining centers to prevent tool chatter, ensuring the block maintains dimensional stability without stress-induced deformation.

Machining the large smooth bore on the side and the small intersecting cross-hole. Drilling titanium is risky due to chip packing. We use through-coolant carbide drills with optimized chip-breaking cycles to effectively evacuate chips. The large bore is then finished with a precision boring bar to ensure perfect concentricity and tight tolerances.

Creating the internal threads in the main port (clearly visible in the center). Tapping titanium conventionally often leads to broken taps stuck in the part. Instead, we use Thread Milling via CNC interpolation. This technique produces cleaner, highly precise threads with zero risk of tool breakage ruining a nearly finished part.

All sharp edges are chamfered (as seen on the outer profiles) for safe handling and proper seal/assembly clearance. The part is then ultrasonically cleaned and transferred to our CMM room. We verify all critical dimensions, especially the perpendicularity between the threaded hole and the side bore, before issuing the final inspection report (available upon request).
