Precision Turned Parts for Robotics, Sensor Technology and Industrial Automation
Whether it is a robot joint, a precision sensor or an electric actuator, modern automation systems only perform reliably when every single precision turned part maintains its characteristics over years of operation. Even the smallest deviations can affect positioning accuracy, measurement quality or service life.
ISO 9001 · ISO 14001 · ISO 13485 · IATF 16949 certified
Made in Switzerland ·· 80+ Years of Experience


Our machinery is built for precision, and our processes make sure it stays that way. Every part that leaves our factory goes through exactly the same checks, whether it’s a prototype or the ten-thousandth piece off the line. IATF 16949/ ISO 9001 / ISO 14001 / ISO 13485 certification isn’t a framed certificate on the wall for us. It means CAQ-driven inspection and watertight documentation, so every batch holds the same standard as the very first approved sample.

What Sets Us Apart As Your Manufacturing Partner
Robotics, sensor technology and industrial automation place the highest demands on repeatability, form accuracy and process stability. What matters is therefore not only the precision of an individual component, but the ability to manufacture it reproducibly over many years and millions of parts.
Since 1939, Häni + Co. AG has manufactured custom precision turned parts for technically demanding applications. We support our customers from initial technical review through co-engineering to economical series production.
Our versatile machine base of conventional single-spindle automatics, CNC single-spindle turning centres, multi-spindle automatics and rotary transfer machines, combined with in-house finishing operations such as centreless grinding and honing, provides the foundation for economical and sustainably stable series processes. This is complemented by CAQ and SPC-supported quality processes that ensure reproducibility across many production batches.
Swiss Precision. Made in Switzerland. Since 1939
What matters most to our customers
Repeatability across every batch
What counts is not the first article sample but batch 50, produced with the same validated process parameters. CAQ-supported inspection processes and SPC for critical characteristics.
Form accuracy as a design criterion
Roundness, cylindricity and straightness are not treated as a by-product of dimensional accuracy. They are separate inspection characteristics, specified on the drawing and anchored in the inspection plan.
Materials expertise for thermally demanding applications
Thermal expansion affects fits. Which material is suitable for an interference fit in a robot joint depends on operating temperature, the mating material and the joining process — not on unit price alone.
Supply chain security
Raw material, tooling or capacity shortfalls hit the line directly. Buffer stock and short decision-making paths are worth considerably more than well-intentioned promises.
Co-engineering before drawing release
Changes made after release cost iterations. We review tolerance specifications for feasibility, materials for suitability, and geometries for process stability — before a line is built.
Documentation that withstands audits
PPAP, IMDS, first article inspection report, SPC evidence — not available on request, but provided as standard.
Precision Manufacturing. Made in Switzerland.
Made in Switzerland means more to us than the highest technical standards alone. It also stands for a personal, collaborative relationship with our customers and a strong record of on-time delivery, something our customers tell us time and again.
Materials expertise for high-volume production
Free-cutting steel, stainless steel, aluminium and lead-free materials are processed with complete material certificates, the foundation of every traceability record and every IMDS entry.
Validated processes for high-volume series
IQ/OQ/PQ-qualified manufacturing steps ensure that every component is produced under the same controlled conditions, traceable and audit-ready.
Complete traceability
Every batch is fully documented in terms of raw material, production parameters and inspection results, throughout the entire legally required retention period.
Consistent quality across every batch
Stable, CAQ-supported processes and statistical process control ensure that the batch produced in two years’ time is every bit as reliable as the first.
Co-Engineering from Day One
We bring our manufacturing knowledge directly into your development process. That typically eliminates secondary operations, locks in process stability and drives down unit costs.
Short Response Times & Direct Decision-Making
With our own raw material warehouse, we can react quickly when delivery quantities or schedules change.
Everything from a Single Source
From turning and finishing to assembly and quality documentation, we coordinate everything.
Precision as our Attitude. Quality is our Standard.
Quality, to us, is not merely an inspection step, it runs through everything we do. In the automotive industry, that means we measure what we promise and document what we measure. This is underpinned by our IATF 16949 certification, which makes the connection between error prevention, process control and documentation binding rather than optional.
Every batch, every component and every process step passes through clearly defined control stages. From prototype through to high-volume series, you can rely on reproducible, audit-ready results at every stage.


Our measurement capabilities span tactile and optical methods, contour measurement and high-precision 3D coordinate metrology. Surface finish, geometry and positional tolerances are all checked at defined intervals under real production conditions. Every step is monitored using statistical process control.

What Buyers and Engineers Want to Know (FAQ)
Who is Häni + Co. AG?
Häni + Co. AG is a Swiss family business founded in 1939, specialising in the manufacture of bespoke precision turned parts. Our strength lies in the cost-effective production of technically demanding components in medium to high volumes, backed by close technical collaboration with our customers throughout.
Based in Arch, canton of Bern, our 65-strong team operates a versatile machine park of conventional and CNC-controlled single-spindle and multi-spindle lathes, as well as rotary transfer machines — producing ready-to-fit precision turned parts across a diameter range of 1 to 65 mm.
We supply companies across a broad range of industries: building services and automation, mobility, electronics and connector technology, medical and laboratory technology, robotics and sensor technology, and renewable energy.
Our processes are certified to IATF 16949, ISO 13485, ISO 14001 and ISO 9001, ensuring the process reliability, quality standards and environmental performance that globally active customers rightly expect.
Where the application demands it, we complement the turning process with in-house secondary operations including honing, centreless grinding, vibratory finishing and roller burnishing. Surface treatments, electroplating in particular, are carried out by long-standing, qualified partner companies.
From development and industrialisation through to on-time series delivery, we work alongside our customers as a dependable manufacturing partner at every stage.
Which application areas in robotics, sensor technology and industrial automation do you manufacture precision turned parts for?
Robotics: Joint shafts, precision axles and transmission components for industrial robots, collaborative robotic systems and automated handling systems.
Sensor technology: Carrier and connector components for pressure, temperature, displacement and position sensors.
Industrial automation: Actuators and components for magnetic drives, valve technology and linear drives.
Which manufacturing processes do you use for turned parts?
Conventional and CNC-controlled multi-spindle automatics and rotary transfer machines for high-volume series. Conventional and CNC-controlled single-spindle automatics for medium-volume series. In-house supplementary operations: centreless grinding, honing, vibratory finishing, roller burnishing. Electroplating and heat treatment via qualified partner companies.
Which batch sizes does Häni + Co. AG manufacture economically?
Our focus is on medium to high-volume series. Thanks to our versatile machine base, however, we support projects from the pre-series stage and provide a seamless transition into series production.
Which materials do you process?
We machine free-cutting steels, stainless steels, aluminium and brass alloys, as well as further materials according to application requirements. We are processing an increasing proportion of lead-free raw materials. We select the most appropriate material together with our customers, taking into account function, machinability and cost-effectiveness.
What tolerances are achievable with CNC turned parts for robotics and sensor technology applications?
We routinely manufacture in the hundredths or thousandths of a millimetre. With appropriate requirements, suitable design, and the right material, these tight tolerances are achievable. In the initial consultation, we discuss together what makes technical sense and is economically feasible for your application.
Can your components be assembled automatically?
Yes, that’s by design. We engineer our components to be assembly-ready from the outset. Feed compatibility, pick-and-place suitability and compatibility with automated assembly equipment are topics we raise in the very first development conversation.
Why is it worthwhile to involve Häni + Co. AG during the development phase?
Many opportunities for optimisation arise before the first chip is cut. By reviewing material selection, tolerances, form and positional tolerances, and manufacturing processes at an early stage, it is possible to reduce manufacturing costs, stabilise processes and avoid design changes later in the project.
Do you handle prototypes and small series as well?
Yes, provided the intention is to scale to medium or larger volumes. For projects that are purely prototypes or very limited runs, we can support you through our partner network where needed. Otherwise, we follow projects all the way from first drawings through pre-production samples to full series manufacturing and we’re at our most useful when we’re involved from the start.
What surface finishes can you offer?
In-house, we offer centreless grinding, honing, roller burnishing, vibratory finishing, and hobbing. We refine your turned parts to micron precision. For processes we do not offer ourselves, we handle the complete coordination including quality control.
How do you ensure process reliability and series stability?
Our manufacturing processes are ISO 9001 certified and CAQ-supported. Every series runs with defined, validated process parameters that are fully documented. Through statistical process control, 3D metrology, and complete batch traceability, we ensure that Batch 1 and Batch 500 are identical. Zero-defect tolerance is not a slogan, it is a concrete goal of our series processes.
Do you offer co-engineering?
Yes, and it’s one of our strongest offerings. Get us involved early and we can work with you to optimise tolerances, materials and geometries together. The result is typically a better part, a simpler process and lower unit costs.
What delivery times and logistics concepts do you offer?
Thanks to our own raw material warehouse, we respond flexibly to changes in demand. We offer VMI warehouse concepts, safety stock, and flexible batch size adjustments. As a Swiss precision parts manufacturer with direct decision-making channels, our response times are short and you always have a direct contact person.
How quickly can I expect a quote?
With complete drawings, we normally come back within three to five working days with a concrete offer. We’re a Swiss family business with short internal chains, decisions get made quickly, and you’ll always speak to someone who knows the project.
How do you ensure traceability?
For every batch, we document material certificates, production parameters, inspection results and despatch records. This information remains available throughout the legally required retention periods.
