Brass Swiss Screw Machined Parts: Product Overview
Brass swiss screw machined parts are precision components produced on Swiss-type automatic screw machines using brass bar stock.
The brass bar stock feeds through a guide bushing positioned immediately at the cutting zone, eliminating workpiece deflection.

- Tight tolerancesReview critical dimensions, datums and mating features and functional requirements before defining the process.
- Single-cycle multi-featureThreading, knurling, cross-drilling, milling — no re-fixturing needed.
- High-volume throughputContinuous automated cycles for millions of parts per year.
Why CNCPioneer for Brass Swiss Screw Machined Parts?
Coordinate geometry, material, finishing and inspection around the part's intended function.
Burr-free surface finish
Brass produces naturally smooth, clean surfaces in screw machining, eliminating secondary deburring operations in most applications and reducing total cost.
Corrosion resistance
Inherently resistant to atmospheric and fluid corrosion; further enhanced with nickel, tin, or chrome plating to meet specific environmental requirements.
Electrical conductivity
Essential for screw machined electrical contacts, terminals, and connector pins where conductivity is a core functional requirement of the part.
Dimensional consistency
Brass's low work-hardening rate ensures stable dimensions across millions of parts in continuous screw machine production runs without drift.
Thread quality
Brass threads cut cleanly and precisely , producing leak-free sealing surfaces critical for fluid control fittings and hydraulic connectors.
