Why 40Cr Steel?
Customers select 40Cr Steel for CNC Punching because it is strong, economical and widely available. We handle grade verification and any required heat treatment or finishing.
Machining 40Cr Steel with CNC Punching
When punching 40Cr 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.
Applications of CNC Punching 40Cr Steel
Typical uses for CNC Punching 40Cr Steel include precision 40Cr Steel components for instrumentation, automotive, medical, energy and general industrial applications.
CNC Punching Quality & Inspection
Each 40Cr Steel part is inspected against your drawing, with critical dimensions verified before release. Material certificates and inspection records are available on request.

Can VT machining make custom 40Cr Steel parts to my drawing?
Yes. 40Cr Steel 40Cr Steel punching 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.
Does CNC Punching 40Cr Steel require dedicated tooling?
Punching uses programmable turret tooling; standard tools cover most patterns, with special tools added for unique forms.
What tolerances can you hold for CNC Punching 40Cr Steel?
Achievable tolerances for 40Cr Steel punching depend on the alloy, geometry and feature size. Punching holds hole-position repeatability to around ±0.10 mm. Exact figures are confirmed against your drawing callouts.
What surface finish is achievable on 40Cr Steel with CNC Punching?
Surface finish on 40Cr Steel is controlled to your specification; we confirm the achievable Ra against your callout.
