- Tolerance to ±0.02 mm
- Hardenable by heat treat
Machining 42CrMo Steel with CNC Wire EDM
When EDM machining 42CrMo Steel, machinability is good to excellent depending on carbon content; free-machining grades cut cleanly. Our process plan reflects this so the finished part holds its tolerances without distortion or poor finish.
Documented parameters for 42CrMo Steel mean predictable cycle times and stable, repeatable results.
Design Tips for CNC Wire EDM 42CrMo Steel
Small design adjustments often cut cost and lead time. EDM suits sharp internal corners, thin ribs and hardened 42CrMo Steel that cannot be milled; allowing a small corner radius where possible speeds the cut. If you send your model early, we will return practical DFM feedback before you commit to production.
Why 42CrMo Steel?
Customers select 42CrMo Steel for CNC Wire EDM because it is strong, economical and widely available. We handle grade verification and any required heat treatment or finishing.
Secondary Operations & Finishing
Most 42CrMo Steel parts need some finishing, which we manage in-house or through vetted partners. Options include deburring and edge-breaking, heat treatment, surface grinding, polishing, and plating or anodising for corrosion resistance and appearance. Give us the finished-part requirement and we will sequence every operation correctly.
CNC Wire EDM Quality & Inspection
Quality is built in, not inspected on. We monitor key features during the run and confirm them at final inspection, with CMM verification available for tight tolerances. We provide the inspection and traceability records your quality system requires.
CNC Wire EDM Tolerances & Surface Finish
EDM holds tolerances to roughly ±0.002–0.005 mm with no cutting force on the 42CrMo Steel part, producing fine, controlled surface textures and sharp internal corners impossible to mill.
Exact achievable figures depend on the alloy, the feature size and the part geometry. Tell us which dimensions are critical and we will advise feasibility up front.
Applications of CNC Wire EDM 42CrMo Steel
42CrMo Steel parts made this way are found throughout aerospace, medical, automotive, electronics and industrial equipment. Prototype, bridge and production volumes are all welcome.
How to Order CNC Wire EDM 42CrMo Steel
Starting your project takes one email. Send your CAD or 2D drawing, the 42CrMo Steel grade and condition, the quantity and any finish or inspection requirements. We respond quickly with price, lead time and any DFM notes, in clear English.
