From real projects

Two cases where the measurement report was only the beginning

ProductionISO GPSDefenceTactile
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.

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We spot withdrawn standards and outdated references before the drawing goes into production.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

How it works

What happens after you get in touch

Using a dimensional inspection as the example.

01
Enquiry
Describe your measurement task and attach the drawing or CAD. Excerpts are fine.
02
Quote
You receive a personal reply with an effort-based quote. You receive the quote before work begins.
03
Measurement
In the temperature-controlled measuring room in Wohlen or on site. You can also drop off parts directly at our premises.
04
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 →

Let's talk about your measurement task.

Describe your measurement task — I will look at it personally.
