VT machining offers CNC Tapping for 316L Stainless Steel (UNS S31603 / 1.4404), typically supplied annealed. Low-carbon 316 for welded and implant-grade parts.
CNC Tapping Notes for 316L Stainless Steel
316L Stainless Steel is tapped with cut taps (spiral-point for through holes) and controlled rigid-tapping speed; thread milling is used where tap breakage would be costly.
For estimating, a 100 × 100 × 10 mm block of 316L Stainless Steel weighs about 0.80 kg.

What surface finish is achievable on 316L Stainless Steel with CNC Tapping?
Surface finish on 316L Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Tapping 316L Stainless Steel and how is it done?
CNC Tapping 316L Stainless Steel refers to rigid CNC tapping cuts internal threads in sync with spindle feed for precise, repeatable thread engagement. Applied to 316L Stainless Steel — corrosion resistant, strong and hygienic — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
What is the typical lead time and minimum order for CNC Tapping 316L Stainless Steel?
CNC Tapping prototypes for 316L Stainless Steel can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
What tolerances can you hold for CNC Tapping 316L Stainless Steel?
Achievable tolerances for 316L Stainless Steel machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Does CNC Tapping 316L Stainless Steel require dedicated tooling?
Most 316L Stainless Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 316L Stainless Steel a good choice for CNC Tapping?
316L Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Tapping. We tune the process to the alloy so the finished 316L Stainless Steel machining part meets your dimensional and functional requirements.
