Typical situations

The most common starting points

Enquiries reach us from purchasing, quality assurance, project management, design engineering and metrology.

For quality assurance and project management

Have parts inspected independently →

First articles, production support or disputed dimensions: CSL measures in a temperature-controlled measuring room — independent and traceable.

For metrology and production

Secure CMM programs and inspection processes →

We write robust CMM programs in Mitutoyo MCOSMOS, Zeiss Calypso, Zeiss Inspect and Hexagon PC-DMIS — offline, while your machine keeps measuring.

For purchasing and incoming goods

Inspect supplied parts before assembly →

Relieve your incoming inspection: CSL checks supplied parts before they are installed and delivers a clear conformity decision.

For supplier quality

Have first articles inspected →

We number every characteristic and document each one individually. The First Article Inspection report follows your template.

For design and development

Clarify drawings and specifications →

Ambiguous drawings usually surface during inspection. ISO GPS drawing review and consulting from someone who comments and votes on the draft standards in the Swiss mirror committee to ISO/TC 213.

Express

Urgent — ask about express measurement

When production is waiting for a result: call us and we will check immediately whether an express measurement is feasible.

From real projects

Two cases where the measurement report was only the beginning

Production

ISO GPS

Defence

Tactile

Reference · Carbomill AG, Seon

Measured red, assembled flawlessly

Carbomill AG in Seon produces complex machined parts. On their behalf, CSL measured a holder for the defence industry on the CMM. The result: not in conformity with the drawing. Yet the assembly trial at the end customer went flawlessly. The drawing described something different from what the function required.

Production

ISO GPS

Zeiss Calypso

Reference · Festo Gewindetriebe AG

First the drawing, then the scale-up

A proven product from Festo Gewindetriebe AG. Quality was never in question: assembly, installation trials and long-term tests were flawless. Only the measurement report kept flagging deviations, because the drawing had grown over the years and no longer fully described the function. Before significantly increasing production volumes, Festo worked with CSL to carry that experience into the drawing.

Standardisation

Christian Schärer sits on the committee that defines the Swiss position on the ISO GPS standards.

He contributes to the development of the standards. Swissmem NK1 is the Swiss mirror committee to ISO/TC 213. The person interpreting your drawing comments on the draft standards himself and votes on the Swiss position.

Current state of the standards

We spot withdrawn standards and outdated references before the drawing goes into production.

Defensible interpretation

For disputed dimensions you receive a justification that holds up — including towards your customer.

Function translated into specification

We translate the function and requirements of your part into a robust specification that conforms to the standards.

Services

From the specification to a defensible conformity decision

A service is the result you receive. The measurement method is the way there.

Dimensional inspection

Independent part inspection — in the temperature-controlled measuring room in Wohlen or on site at your facility. First articles, production support and disputed dimensions.

CMM programming

Robust CMM programs in Mitutoyo MCOSMOS, Zeiss Calypso, Zeiss Inspect and Hexagon PC-DMIS. Written offline — no machine downtime at your site.

View CMM programming →

ISO GPS services →

Consulting, workshops, drawing review and correction.

CSL Quality Gate →

Inspect entire delivery lots before they reach assembly.

Measurement process capability →

Evaluate measurement systems and inspection processes to the standards.

Reverse engineering →

From the physical part to the CAD model.

Laboratory

Which method for which characteristic

The right method for each inspection characteristic. Measured in our laboratory in Wohlen or on site at your facility.

How it works

What happens after you get in touch

Using a dimensional inspection as the example.

Enquiry

Describe your measurement task and attach the drawing or CAD. Excerpts are fine.

Quote

You receive a personal reply with an effort-based quote. You receive the quote before work begins.

Measurement

In the temperature-controlled measuring room in Wohlen or on site. You can also drop off parts directly at our premises.

Report

Measurement report as PDF with a numbered inspection sketch. For multiple parts, an additional Excel matrix of all dimensions for further processing.

Turnaround

Typically 3 to 5 working days. A substantial part of this is acclimatisation to 20 °C in accordance with ISO 1.

Results review

A 30-minute review of the results is included — online or at our site in Wohlen. Optional, not mandatory.

Confidentiality

Drawings and CAD data stay with us; NDA before the first file on request. How we handle it →

Frequently asked

In brief

Do you work throughout Switzerland?

Yes. Parts reach us by post, courier or personal delivery from all over Switzerland — goods reception Monday to Friday, 08:00–17:00. For CMM programs and on-site support we also come to you.

What does a measurement cost?

Quotes are effort-based and transparent: the number of inspection characteristics, the quantity of parts and the depth of documentation determine the price. Describe your measurement task — you will receive a personal reply with a quote.

Do you communicate in English?

Yes — enquiries, quotes, measurement reports and results reviews are available in English. Drawings and specifications based on ISO GPS or ASME GD&T are both handled.
