What Kunz Precision does

Kunz Precision AG is a Swiss precision metrology company headquartered in Zofingen, Switzerland, founded in 1980 and operating with 11–50 employees. The firm specializes in high-precision measurement instruments and accredited calibration services built around proprietary vacuum-air bearing technology that delivers nanometer-level accuracy and repeatability. Kunz holds Swiss Calibration Service (SCS) ISO/IEC 17025 accreditation, first obtained in 1987 as the first such laboratory in Switzerland and renewed for the 2023–2028 cycle, which underpins its credibility as a traceable calibration provider.

The product portfolio comprises high-precision measurement instruments, customized measurement systems, and specialized instruments such as the LTP-1400 Long Trace Profiler used in neutron accelerator optics. Underlying technology rests on a proprietary vacuum-air bearing design combined with optical/metrological measurement methods refined over more than four decades. Complementary offerings include accredited calibration services, Q-Support training and capability analyses, and a TESA Silver Service Partner distribution and service arrangement. The firm is also extending its technology perimeter through R&D partnerships, notably with CSEM on a Grating Machine and with Parriaux Consulting.

Kunz generates revenue from three streams: one-time sales of high-precision measurement instruments and customized measurement systems, recurring accredited calibration services, and training/consulting engagements (Q-Support). The customer base is diversified across the watchmaking industry (Patek Philippe, IWC Schaffhausen, Cartier, ETA SA), medical technology (Roche Diagnostics, Stryker Osteosynthesis), machine industry (DMG MORI SEIKI, Bystronic Laser, Fehlmann, Carl Zeiss, Leica Geosystems, Mitutoyo), national metrology and research institutes (METAS, PTB, NIM Thailand, Paul Scherrer Institut, Fraunhofer IAF), and industrial/transport customers (BLS AG, SBB, RUAG, Pilatus, Axpo Power, MAN Diesel & Turbo, Caterpillar, SR Technics). Geographically, the firm serves Switzerland, Germany, USA, Thailand, Liechtenstein, and Taiwan, positioning itself as a globally reachable niche specialist.

Comparable on high-precision optical/metrology systems; broader portfolio and global scale but overlapping on optical surface and mask measurement where Kunz operates (Zeiss is also a Kunz customer).

Direct peers

• Renishaw: UK-based global leader in precision measurement, encoders, and calibration products serving machine tool, semiconductor, and research customers. Directly comparable in calibration/positioning precision and machine-geometry product lines; Kunz even lists Mitutoyo and Renishaw as adjacent ecosystem players.
• Heidenhain: German manufacturer of high-precision linear encoders, length gauges, and machine-tool inspection systems. Comparable on linear measurement accuracy and machine-geometry applications; broader industrial scale but overlapping technology stack.
• Mahr Group: German precision measurement specialist producing length, form, and surface metrology instruments. Direct comparable on dimensional metrology and calibration services for industrial customers in the DACH region.
• SIOS Messtechnik: German specialist in laser interferometry and nanometer-precision length/angle measurement systems. Highly comparable on nanometer-precision technology and customer base in research institutes and machine-tool builders.
• TESA Technology (Hexagon Manufacturing Intelligence): Swiss precision height gauges and length measurement brand, now part of Hexagon. Kunz is a TESA Silver Service Partner and resells TESA height instruments; TESA competes head-on with Kunz's straightness, length, and squareness product families.
