VT machining offers CNC 4-Axis Machining for 316 Stainless Steel (UNS S31600 / 1.4401 / SUS316), typically supplied annealed. Molybdenum adds chloride/pitting resistance over 304; tougher to cut than 304.
CNC 4-Axis Machining Notes for 316 Stainless Steel
Multi-axis machining lets 316 Stainless Steel parts be completed in one or two setups, which improves feature-to-feature accuracy.
For estimating, a 100 × 100 × 10 mm block of 316 Stainless Steel weighs about 0.80 kg.

Does CNC 4-Axis Machining 316 Stainless Steel require dedicated tooling?
Most 316 Stainless Steel machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
Why is 316 Stainless Steel a good choice for CNC 4-Axis Machining?
316 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC 4-Axis Machining. We tune the process to the alloy so the finished 316 Stainless Steel machining part meets your dimensional and functional requirements.
What tolerances can you hold for CNC 4-Axis Machining 316 Stainless Steel?
Achievable tolerances for 316 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.
What surface finish is achievable on 316 Stainless Steel with CNC 4-Axis Machining?
Surface finish on 316 Stainless Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC 4-Axis Machining 316 Stainless Steel and how is it done?
CNC 4-Axis Machining 316 Stainless Steel refers to four-axis machining adds a rotary axis for indexed or continuous machining around a part. Applied to 316 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.
Can VT machining make custom 316 Stainless Steel parts to my drawing?
Yes. 316 Stainless Steel machining 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.
