About us

FRENCO GmbH was founded in 1978 and has since then been engaged in the special field of Gear and Spline Metrology.

Most of today’s gears and splines are precision items, for whose production both expertise and special tooling with very tight tolerances are required.

In order to measure the manufactured workpieces, companies need even more accurate measuring and inspection equipment. FRENCO has committed itself to this challenge:


Gear and Spline Metrology








Our FRENCO concept is characterised by consistent quality and customer orientation. Customer preferences and requirements can always be integrated, as we only start manufacturing the measurement solution on receipt of the order. We also place a lot of emphasis on service, flexibility and quality. This is reflected in our slogan:

Company Information

Our custom QM system is subject to constant changes and improvements. It contains, amongst others, the following elements:

  • description of the QM system in form of guidelines
  • at least random, if possible 100% testing of produced goods
  • incoming material inspection
  • unique identification of the products
  • production control at regular intervals
  • systematic intermediate and final inspections by means of inspection plans and inspection instructions
  • issuing of inspection certificates
  • direct traceability of measuring results to national artefacts
  • documentation of inspection results with a 10-year retention period
  • internal and external computer-aided monitoring of inspection equipment
  • recording of quality relating coststraceability to the sub-supplier
  • procedure to process complaints, identify the cause of error and prevent future errors
  • guidelines for all business sectorsquality assurance officer
  • FRENCO is not certified in accordance with ISO 9000 et seq. and only aims at such certification in the longer term. The main reason for this decision is the fact that the quality of our products and services are not dependant on certification and cannot be proven by such certification either. Although our QA system has very much been influenced by ISO/QS 9000, many formal requirements are not fulfilled. We feel that this bureaucratic effort is unreasonable with respect to a predominantly single item production and a workforce of approximately 70 employees. In this respect, we fulfil what is essential for us, e.g. documentation of rules in specific problems.
  • Advanced tasks, such as application-relevant support for our customers and quick implementations of new findings and experiences are important to us. Accordingly, we have set ourselves the following medium-term targets, from which our customers in the main will benefit:

100% final inspection of all gear profiles that must have gauge quality. Reduction of measurement uncertainties during gear and spline inspection improving existing and developing of new inspection methods for industrial metrology of gearing Guaranteeing of comparability of all measuring results with calibrated artefacts and ring comparisons Instead of a certificate, which is with regard to product quality rather questionable anyway, we offer the following:

  • Every customer is welcome to visit us on short notice to learn about our QM system.
  • We are happy to undergo auditing by our customers.
  • In audits according to IATF 16949 we constantly score 95% to 100% results.

This ensures that our customers can verify requirements, which may even exceed those of ISO/QS 9000, and establishes mutual trust.

The future development of FRENCO GmbH is continuously focused on improved technology. The further development refers to the qualification of staff, the internal processes and their transparency as well as to the products offered on the market consisting of mechanics, electronics and software.

FRENCO is striving for uniqueness, with the services and products offered, which are otherwise not available on the market in this particular form. None of the products is to be comparable to those of the competition. Our efforts are focussed on good products and services and should not be devoted to offering comparable products at a cheaper price compared to those of our competitors. There is a particular emphasis on the humane personal characteristics of our employees, as well as their best possible qualifications and placement at the right position within the company. All employees shall take pleasure and pride in testing new technologies and in implementing them. This requires much creativity, which is encouraged within the company through high levels of freedom for the employees. The interaction between people within the company and outside should be honest and straightforward.

Control is limited to the essential, excessive control is avoided. FRENCO’s planning schedules are long-term. Continuity should be connected to steady growth of expertise in gear metrology.
