VT machining offers CNC 5-Axis Machining for 317L Stainless Steel (UNS S31703 / 1.4438), typically supplied annealed. More Mo than 316L for harsher chemical service.
CNC 5-Axis Machining Notes for 317L Stainless Steel
For a hard-to-cut grade like 317L Stainless Steel, multi-axis machining reduces the number of setups, so there are fewer re-clamps and less time spent cutting.
For estimating, a 100 × 100 × 10 mm block of 317L Stainless Steel weighs about 0.80 kg.

What is CNC 5-Axis Machining 317L Stainless Steel and how is it done?
CNC 5-Axis Machining 317L Stainless Steel refers to five-axis machining orients the tool to complex geometry in one setup, reducing fixturing and improving accuracy. Applied to 317L 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 tolerances can you hold for CNC 5-Axis Machining 317L Stainless Steel?
Achievable tolerances for 317L 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 5-Axis Machining 317L Stainless Steel require dedicated tooling?
Most 317L Stainless Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 317L Stainless Steel a good choice for CNC 5-Axis Machining?
317L Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC 5-Axis Machining. We tune the process to the alloy so the finished 317L Stainless Steel machining part meets your dimensional and functional requirements.
What surface finish is achievable on 317L Stainless Steel with CNC 5-Axis Machining?
Surface finish on 317L Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
