Why is Grade 3 Titanium a good choice for CNC Thread Grinding?
Grade 3 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Thread Grinding. We tune the process to the alloy so the finished Grade 3 Titanium grinding part meets your dimensional and functional requirements.
Does CNC Thread Grinding Grade 3 Titanium require dedicated tooling?
Most Grade 3 Titanium grinding work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is CNC Thread Grinding Grade 3 Titanium and how is it done?
CNC Thread Grinding Grade 3 Titanium refers to thread grinding produces precise, high-finish threads on hardened parts and lead screws. Applied to Grade 3 Titanium — high strength-to-weight, biocompatible and corrosion resistant — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can VT machining make custom Grade 3 Titanium parts to my drawing?
Yes. Grade 3 Titanium grinding is made to order from your CAD/2D drawing. Share your geometry, material grade, tolerance and quantity and we will confirm feasibility, lead time and pricing.
What surface finish is achievable on Grade 3 Titanium with CNC Thread Grinding?
Grinding can take Grade 3 Titanium to a fine finish — typically Ra 0.1–0.4 µm, and to a mirror grade on suitable alloys.
