VT machining offers CNC Tapping for C377 Brass (UNS C37700 / CuZn39Pb2 / Forging brass), typically supplied as forged. Best hot-forging brass; forged near-net then machined.
CNC Tapping Notes for C377 Brass
C377 Brass is ductile enough for form (roll) tapping, which gives stronger, chip-free threads; cut taps are used where the drawing or material condition requires.
For estimating, a 100 × 100 × 10 mm block of C377 Brass weighs about 0.84 kg.
Starting Parameters for CNC Tapping C377 Brass

Does CNC Tapping 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.
What is CNC Tapping C377 Brass and how is it done?
CNC Tapping C377 Brass refers to rigid CNC tapping cuts internal threads in sync with spindle feed for precise, repeatable thread engagement. 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.
What tolerances can you hold for CNC Tapping C377 Brass?
Achievable tolerances for C377 Brass machining depend on the alloy, geometry and feature size. Milling holds positional and dimensional tolerances to around ±0.01 mm, tighter with precision setups. Exact figures are confirmed against your drawing callouts.
Why is C377 Brass a good choice for CNC Tapping?
C377 Brass is free-machining with good conductivity, which makes it well suited to CNC Tapping. We tune the process to the alloy so the finished C377 Brass machining part meets your dimensional and functional requirements.
What is the typical lead time and minimum order for CNC Tapping C377 Brass?
CNC Tapping prototypes for C377 Brass can be produced quickly and scaled to series production. Send your drawing and quantity and we will advise lead time and any minimum order.
