What material thickness or size range suits CNC Surface Grinding Grade 23 Titanium?
We machine Grade 23 Titanium across a broad size range; share your part envelope for confirmation.
What is CNC Surface Grinding Grade 23 Titanium and how is it done?
CNC Surface Grinding Grade 23 Titanium refers to surface grinding produces flat, parallel faces with fine finish using a horizontal abrasive wheel. Applied to Grade 23 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.
Why is Grade 23 Titanium a good choice for CNC Surface Grinding?
Grade 23 Titanium is high strength-to-weight, biocompatible and corrosion resistant, which makes it well suited to CNC Surface Grinding. We tune the process to the alloy so the finished Grade 23 Titanium grinding part meets your dimensional and functional requirements.
What tolerances can you hold for CNC Surface Grinding Grade 23 Titanium?
Achievable tolerances for Grade 23 Titanium grinding depend on the alloy, geometry and feature size. Grinding routinely holds single-micron tolerances on diameter, flatness and parallelism. Exact figures are confirmed against your drawing callouts.
What is the typical lead time and minimum order for CNC Surface Grinding Grade 23 Titanium?
CNC Surface Grinding prototypes for Grade 23 Titanium can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
