Titanium Machining Expertise
Titanium machining requires specialized expertise due to the material's low thermal conductivity, chemical reactivity with cutting tools, and spring-back tendency. At CastAlloy, we have refined our titanium machining processes through extensive production experience, utilizing sharp positive-rake carbide tooling, high-pressure coolant systems, and rigid workholding setups to deliver dimensionally accurate components with excellent surface integrity. We machine both cast and forged titanium blanks across all common grades.
Capabilities & Quality
Our titanium machining capabilities include multi-axis CNC milling, CNC turning, precision drilling and reaming, thread milling, and surface grinding. We achieve tolerances as tight as ±0.0005 inches and surface finishes to 16 Ra µin on titanium components. Quality inspection includes CMM verification, surface roughness measurement, and visual inspection per applicable aerospace and medical standards. Full documentation packages with FAI reports, CoC, and material certifications are provided with every shipment.

Frequently Asked Questions
Titanium's low thermal conductivity causes heat to concentrate at the cutting edge rather than dissipating through chips. Combined with its chemical affinity for tool materials (causing galling and built-up edge) and its low elastic modulus (causing spring-back and chatter), titanium requires slower speeds, positive-rake sharp tools, rigid setups, and generous coolant flow.
