Swiss CNC Machined Parts | Custom Precision Manufacturing

Product Overview

Swiss CNC machining delivers high-precision, tight-tolerance cylindrical components combining simultaneous turning and milling. Ideal for complex, slender, and micro-sized parts with high length-to-diameter ratios. Guided by sliding headstock technology and synchronized live tooling, raw bar stock feeds through a guide bushing, minimizing deflection and maintaining micron-level precision across large production runs. Manufactured in an ISO 9001-certified facility equipped with automated bar loaders for 24/7 high-precision production. Suitable for parts ranging from 1 mm to 32 mm in diameter.

Key Features

Dimensional Accuracy:

Achieves tight tolerances down to +/- 0.005 mm through sliding headstock guide bushing support, preventing workpiece deflection during deep cuts.

Batch Repeatability:

Sub-micron positioning and automated bar feeding ensure consistent part geometry from the first piece to the ten-thousandth piece.

Complex Geometry:

Multi-axis capability integrates turning, milling, axial/radial drilling, and slotting in a single clamping operation, eliminating repositioning errors.

Small-to-Large Batch Production:

Optimized for medium-to-high volume production runs with rapid changeover times and minimal unattended cycle downtime.

Superior Surface Quality:

Optimized feed rates and high-pressure coolant systems maintain fine surface finishes, reducing secondary polishing operations.

FAQ

Q: What is your Minimum Order Quantity (MOQ)?

A: No strict MOQ for production runs, though batch pricing is optimized for quantities above 100 pieces due to CNC setup efficiency. Prototypes accepted.

Q: What tolerance ranges can you reliably hold?

A: Standard dimensional tolerances are +/- 0.01 mm, with precision features held down to +/- 0.005 mm or tighter depending on material and geometry.

Q: Can you provide material certificates?

A: Yes. Mill test certificates (MTRs) and RoHS/REACH compliance documentation are supplied with every shipment.

Q: How are samples handled before mass production?

A: First Article Inspection (FAI) reports along with initial physical samples are submitted for customer sign-off prior to releasing full batch production.

Q: What file formats are required for quoting?

A: STEP, IGES, or Parasolid 3D files combined with a 2D PDF drawing containing explicit tolerances, surface finish requirements, and thread specifications.

Q: What is the standard production lead time?

A: Typically 2 to 4 weeks from order confirmation and drawing approval, depending on raw material availability and required surface treatments.
