VT machining offers CNC Turning for SPCC Steel (JIS G3141 / ~DC01 / ~1008 CR), typically supplied cold-rolled sheet. Cold-rolled commercial sheet with clean surface for painting.
CNC Turning Notes for SPCC Steel
SPCC Steel turns with good chip control at standard cutting data.
For estimating, a 100 × 100 × 10 mm block of SPCC Steel weighs about 0.79 kg.
