VT machining offers CNC Press Brake Forming for SECC Steel (JIS G3313 electro-galvanised SPCC), typically supplied cold-rolled, EG coated. Thin, smooth zinc coating for painted or bare electronics enclosures.
CNC Press Brake Forming Notes for SECC Steel
SECC Steel bends to a tight inside radius (about 1× thickness) in this condition.
For estimating, a 100 × 100 × 10 mm block of SECC Steel weighs about 0.79 kg.

What tolerances can you hold for CNC Press Brake Forming SECC Steel?
Achievable tolerances for SECC Steel forming depend on the alloy, geometry and feature size. We hold tight, repeatable tolerances appropriate to the feature and material. Exact figures are confirmed against your drawing callouts.
Why is SECC Steel a good choice for CNC Press Brake Forming?
SECC Steel is strong, economical and widely available, which makes it well suited to CNC Press Brake Forming. We tune the process to the alloy so the finished SECC Steel forming part meets your dimensional and functional requirements.
Does CNC Press Brake Forming SECC Steel require dedicated tooling?
Most SECC Steel forming work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
What surface finish is achievable on SECC Steel with CNC Press Brake Forming?
Surface finish on SECC Steel is controlled to your specification; we confirm the achievable Ra against your callout.
What material thickness or size range suits CNC Press Brake Forming SECC Steel?
We form SECC Steel sheet and plate to your developed flat pattern and bend sequence.
Can VT machining make custom SECC Steel parts to my drawing?
Yes. SECC Steel forming 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.
