Expert CNC Multi Axis Swiss Turning Services for Precision Parts

CNC Swiss turning uses sliding headstock lathes with multiple axes (typically X, Z, C-axis, and often B-axis or sub-spindle) to machine complex precision parts from bar stock. These machines require specialized calibration because they combine linear positioning, rotary indexing, and synchronized motion across multiple tooling stations. Even minor positioning errors in any axis directly impact thread quality, concentricity, and surface finish on precision turned components.

Our Renishaw Laser Interferometer provides accuracy to 1.0 parts per million—equivalent to one millionth of an inch per inch of travel. This exceeds the 10:1 ratio required for proper calibration and ensures measurements are fully traceable to NIST and International Standards. This level of precision is essential for Swiss turning operations producing medical devices, aerospace components, and instrumentation parts.

Calibration identifies positioning inaccuracy, poor repeatability, axis straightness errors, squareness problems between axes, backlash in rotary components, servo mismatch, reversal errors, and mechanical wear. For Swiss lathes, we also evaluate sub-spindle alignment, C-axis indexing accuracy, and synchronization issues that affect thread milling and eccentric turning operations.

New machines should be verified immediately after installation to catch shipping damage or setup errors while still under warranty. Established machines benefit from annual calibration or whenever accuracy issues arise. High-volume operations producing critical precision parts may require more frequent verification, especially after crashes, major repairs, or when tolerances tighten.

All calibration is performed on-site at your facility using portable measurement systems. Swiss turning machines remain in place, minimizing downtime and eliminating the cost and risk of machine relocation. Our wireless Ballbar and laser interferometer systems allow efficient testing with minimal disruption to production operations.

Primary service area covers Portland OR and SW Washington with faster response times than out-of-area providers. We also provide calibration services to customers outside this region who require NIST-traceable accuracy and comprehensive multi-axis verification for Swiss turning operations.

Complete multi-axis calibration typically requires 4-8 hours depending on machine size, number of axes, and travel length. Ballbar testing provides rapid machine health assessment in 1-2 hours. We schedule service to minimize production impact and can often work during off-shifts or planned maintenance windows.

Yes, every calibration includes comprehensive documentation with NIST-traceable certification. Reports detail measurements for each axis, identify out-of-tolerance conditions, and provide before/after comparisons when adjustments are made. This documentation supports ISO compliance, customer audits, and warranty claims for Swiss turning operations.
