Precision parts manufacturing –
ready for installation & documented
Precision comes from a stable process chain: clean data, suitable strategies, reliable manufacturing and traceable quality. As a partner for general precision engineering, we supply precise, machined precision parts that meet the specified parameters – from prototypes to series production, ready for installation and with clear documentation. We are used to components that require out-of-the-box thinking.
We will check feasibility and get back to you shortly.
What precision engineering means to us is
Our precision engineering combines design-oriented consulting (DFM) with reproducible manufacturing and documented quality. We think in terms of reference surfaces, tolerance chains and process windows – with the aim of minimising risks, shortening ramp-ups and reliably meeting deadlines.
Precision parts manufacturing:
From DFM to series production
We start with an honest DFM check (radii, wall thicknesses, accessibility, reference/clamping concept). From this, we derive the most economical process chain – right down to measuring points, marking and packaging. Precision parts are only finished when function, dimensions and surface finish match – documented and reproducible.
Part categories
& Geometries
We manufacture miniature and complex precision parts as well as medium-sized/large milled and turned parts. Free-form surfaces, sealing and fitting surfaces, defined edge logic and ready-to-use threads/seats are all part of the process. Where appropriate, we supplement machining processes with eroding or defined finishes.
Ready-to-install components: surfaces, edges, packaging
Ready for installation means: defined surface characteristics, low-burr and low-edge design, cleaned components in accordance with specifications, threads and fits checked, and packaged in accordance with factory logistics (labelling, corrosion protection, container cycles).

Quality & evidence:
measurement report, 100% inspection, traceability
Quality is measurable. We define test plans, check all relevant characteristics tactilely/visually and, on request, provide 100% testing. Measurement reports include reference surfaces, temperature specifications and measuring equipment references. Traceability (e.g. batch/serial number, QR/data matrix) is available.
UHV & cleanroom-compatible components
For UHV-components and cleanroom-compatible components we pay attention to suitable materials, reproducible surfaces and controlled cleaning/packaging. Sealing surfaces, particle behaviour and media compatibility are coordinated by us with your design; the verifications are based on your specification.
From prototype to small-batch/series production
After the prototype, we stabilise parameters, reduce transformer ratios and secure cycle times – this makes it possible to plan the transition to small series production and series production. We document iterations for fine-tuning functions and costs in a transparent manner.
Quality assurance in accordance with ISO 9001 –
measurable, documented, traceable
At Bonsack, quality is not a matter of chance, but the result of structured processes. Our quality assurance begins during production and only ends with delivery. All products undergo extensive testing in our modern testing laboratory, which is equipped with several 3D coordinate measuring machines from Carl Zeiss.
This is how we ensure that that each component precisely meets the technical specifications – regardless of quantity or complexity.
FAQ Precision parts manufacturing
What evidence will I receive?
Measurement report, 100% inspection on request, material/batch certificates and labelling in accordance with specifications.
Are complex free forms possible?
Yes – using suitable 5-axis strategies and reference concepts and, if necessary, complex special tool geometries.
Do you deliver ready to install?
Yes – with defined surfaces/edges, tested threads/fits and packed according to your specifications.
UHV/clean room requirements?
Covered – with suitable materials, separate cooling lubricant, cleaning/packaging and documented evidence in accordance with customer requirements.
How does the transition to the series work?
Via small series and optimisation loops for parameter stabilisation, followed by scaled batches with constant cycle times.
