Swiss Machining for Small, Complex Precision Parts
BGCNC supports engineers and procurement teams with high-precision Swiss machining for small-diameter components, demanding geometries, and consistent production runs.
Using a sliding headstock and guide bushing close to the cutting tool, we produce long, slender parts with reduced vibration and deflection—well suited to medical, electronics, automotive, instrumentation, and connector applications.

Typical units
Complex features, one setup
Combine turning, milling, drilling, and cross-drilling in one cycle.
Built for repeat orders
Process control and in-process inspection help sustain batch consistency.
Technical capabilities
Precision control for slender, intricate parts
Guide-bushing support stabilizes long, small-diameter stock near the cutting zone. That support helps limit deflection while machining demanding profiles and features.

Designed for production
More than machine time: a controlled supply path
For small-part production, repeatability across thousands of units matters as much as the first-article result. BGCNC coordinates engineering, production, and quality planning around your requirements.
Reduce secondary operations
Machining complex milling and cross-drilled features on the Swiss lathe can reduce extra setups, unit cost, and tolerance stack-up.
Maintain batch consistency
In-process inspection protocols support consistent production from the first component through the full repeat run.
Coordinate finishing services
We can integrate ultrasonic cleaning, heat treatment, passivation, and specialized coatings to help deliver ready-to-assemble parts.
Industry applications
Small components for precision-critical sectors
Medical & dental
Surgical instruments, bone screws, and connector housings.
Electronics & telecommunications
Precision pins, standoffs, and fiber-optic components.
Automotive
Fuel-system sensors, micro-valves, and instrumentation parts.
Industrial automation
Precision actuators and sensor-housing components.
Our supply-chain network includes partners with ISO 13485 (medical) and IATF 16949 (automotive) certifications, helping align projects with the appropriate quality management system.
Process selection
Is Swiss machining right for your project?
Not every small component needs a Swiss lathe. BG CNC evaluates your drawing, geometry, and expected annual volume to identify a cost-effective route.
Get a DFM reviewA strong Swiss machining candidate
High-volume, small-diameter parts with complex features
Swiss machining is often an economical choice when a part combines slender geometry, tight tolerances, or multiple machined features with repeat demand.
Another process may be more suitable
Simple geometry or very low prototype quantities
For simple parts or very small quantities, such as 5–10 prototypes, standard CNC turning may avoid unnecessary setup cost.
Every quote includes a Design for Manufacturing (DFM) review so the proposed process fits the part and production plan.
