VT machining offers CNC Reaming for C377 Brass (UNS C37700 / CuZn39Pb2 / Forging brass), typically supplied as forged. Best hot-forging brass; forged near-net then machined.
CNC Reaming Notes for C377 Brass
Reaming C377 Brass gives H7 holes with a fine finish; stock allowance is set by hole diameter so the reamer cuts cleanly.
For estimating, a 100 × 100 × 10 mm block of C377 Brass weighs about 0.84 kg.

Why is C377 Brass a good choice for CNC Reaming?
C377 Brass is free-machining with good conductivity, which makes it well suited to CNC Reaming. We tune the process to the alloy so the finished C377 Brass machining part meets your dimensional and functional requirements.
What surface finish is achievable on C377 Brass with CNC Reaming?
Surface finish on C377 Brass is controlled to your specification; we confirm the achievable Ra against your callout.
What is CNC Reaming C377 Brass and how is it done?
CNC Reaming C377 Brass refers to reaming finishes drilled holes to a precise diameter and smooth surface in a single controlled pass. Applied to C377 Brass — free-machining with good conductivity — VT machining produces each part to your CAD drawing, selecting parameters from your tolerance, finish and quantity requirements.
Can VT machining make custom C377 Brass parts to my drawing?
Yes. C377 Brass machining 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 Reaming C377 Brass require dedicated tooling?
Most C377 Brass machining work uses standard cutting tools and CNC programs; dedicated fixtures are made only when geometry or volume requires them.
