How clean are the edges produced by CNC Honing on 309 Stainless Steel?
Our deburring leaves 309 Stainless Steel with a consistent, controlled edge break and burr-free surfaces.
Why is 309 Stainless Steel a good choice for CNC Honing?
309 Stainless Steel is corrosion resistant, strong and hygienic, which makes it well suited to CNC Honing. We tune the process to the alloy so the finished 309 Stainless Steel finishing part meets your dimensional and functional requirements.
Does CNC Honing 309 Stainless Steel require dedicated tooling?
Most 309 Stainless Steel finishing work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What is CNC Honing 309 Stainless Steel and how is it done?
CNC Honing 309 Stainless Steel refers to honing finishes bores with abrasive stones to precise size, roundness and a cross-hatch surface. Applied to 309 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 309 Stainless Steel parts to my drawing?
Yes. 309 Stainless Steel finishing 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 309 Stainless Steel with CNC Honing?
Our finishing processes refine 309 Stainless Steel surfaces to Ra values as low as 0.05 µm for cosmetic or sealing faces.
