VT machining offers CNC Punching for 1018 Steel (UNS G10180 / C15 / S20C), typically supplied cold-drawn. The most common low-carbon machining bar; good finish and carburisable.
CNC Punching Notes for 1018 Steel
1018 Steel punches cleanly with standard clearance; minimum hole diameter is about the sheet thickness.
For estimating, a 100 × 100 × 10 mm block of 1018 Steel weighs about 0.79 kg.

How clean are the edges produced by CNC Punching on 1018 Steel?
Punched 1018 Steel edges are clean when punch/die clearance is correct; we set clearance to the gauge and can add deburring if specified.
What tolerances can you hold for CNC Punching 1018 Steel?
Achievable tolerances for 1018 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.
Why is 1018 Steel a good choice for CNC Punching?
1018 Steel is strong, economical and widely available, which makes it well suited to CNC Punching. We tune the process to the alloy so the finished 1018 Steel punching part meets your dimensional and functional requirements.
What is CNC Punching 1018 Steel and how is it done?
CNC Punching 1018 Steel refers to cNC turret punching shears holes and form features in sheet metal using programmable tooling for fast, repeatable patterns. Applied to 1018 Steel — strong, economical and widely available — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
