VT machining provides CNC Broaching 440C Stainless Steel for customers who need accurate, repeatable 440C Stainless Steel components. The machinability of 440C Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing, so we set the operation up specifically for this grade.
CNC Broaching Capability for 440C Stainless Steel
- Austenitic/martensitic grades
- Corrosion resistant
- Tolerance to ±0.01 mm
- Typical hardness 70–200 HB (annealed)
Machining 440C Stainless Steel with CNC Broaching
The machinability of 440C Stainless Steel is moderate; work-hardens, so positive-rake tooling and steady feeds are used to avoid glazing. For CNC Broaching we select tooling, feeds, speeds and coolant to match, keeping the 440C Stainless Steel workpiece stable and the result accurate.
Because we machine 440C Stainless Steel regularly, proven settings shorten setup and keep quality repeatable across reorders.
Why 440C Stainless Steel?
Specifying 440C Stainless Steel for CNC Broaching 440C Stainless Steel is usually about its properties: corrosion resistant, strong and hygienic. Tell us the condition you need and we machine to it.
Secondary Operations & Finishing
We complete 440C Stainless Steel components with the secondary steps your drawing calls for. We arrange heat treatment, surface treatment, marking and assembly as needed. Tell us the final spec and we will plan the full route so parts arrive ready to use.
Design Tips for CNC Broaching 440C Stainless Steel
A few design choices make a real difference to cost and quality. Generous internal radii, sensible pocket depth-to-width ratios and avoiding very thin unsupported walls all reduce cost and improve accuracy in 440C Stainless Steel. If you send your model early, we will return practical DFM feedback before you commit to production.
CNC Broaching Tolerances & Surface Finish
For CNC Broaching, dimensional and positional tolerances around ±0.01 mm are routine, tightening toward ±0.005 mm on precision setups. Surface finish on machined faces typically falls in the Ra 0.4–1.6 µm range depending on tooling and pass strategy.
The tightest tolerances are reserved for the features your drawing flags as critical. Share your tolerance scheme and we will confirm what is realistic before quoting.
CNC Broaching Quality & Inspection
Consistent quality comes from disciplined process control. Critical dimensions on 440C Stainless Steel parts are checked in-process and verified at final inspection using calibrated instruments and, where required, CMM measurement. Full documentation — dimensional reports, mill certs, FAIR — is available when your programme needs it.
Applications of CNC Broaching 440C Stainless Steel
CNC Broaching of 440C Stainless Steel supports parts across aerospace, medical, automotive, electronics, semiconductor, energy and general industrial sectors. We scale from one-off prototypes to ongoing production while holding the same quality.
