Micro Switches

A global business demand micro-precision measurement and inspection of machined parts

C&K is a manufacturer of a wide range of micro switches used in many applications world-wide. The business offers more than 55,000 standard products and 8.5 million switch combinations in many different designs used in the industrial, automotive, consumer electronics, telecom, space, and medical sectors. Manufacture of these switches and other machined parts require the accurate inspection and measurement of both micro finish and micro geometry. As some of these products are safetycritical, these accurate measurements are vital; switches could fail in use or become stuck in an inoperable condition.

Our micron tolerance level machines met the brief for automated part inspection

The main application is the validation and inspection of machined parts in wire EDM (Electrical Discharge Machining), sinker EDM or HSM (High Speed machining), by fitting and comparing the scanned datasets with the nominal shapes from CAD files. The tolerances are in the range of a few microns. By measurement of the stamping tools and dies used to manufacture these products, they can maximise tool life by measuring wear against CAD models. These components are very small, as can be seen in the 3D models produced by the InfiniteFocus in the illustrations below.  According to Mr Gagey, they are very challenging to measure; with shiny surfaces and a complex form.These small machined partsrequire the fusion of several 3D data sets with high precision. The Bruker Alicona system fitted with the Advanced Real3D rotation device achieves this, automatically producing high quality, dense and robust 3D models that can easily be compared against original CAD data.

Alicona InfiniteFocus G6

We recommend The Bruker Alicona InfiniteFocusG6 optical 3D measurement system with an advanced real 3D Rotation Unit (an upgrade from the G5 shown above with Laurent Gagey of C&K) to solve these challenges. The geometric measurement, surface profile and finish data has helped improve quality in the manufacture of these switches, tackling the complexity of these parts as demonstrated in the image.

Trusted by the World's Most Innovative Brands

The Optimax team with their extensive knowledge and expertise, have proven themselves to be the ideal partner for independent, candid advice. They are a company we can trust to support our metrology and visual inspection needs whether we are purchasing equipment or developing specific metrology instruments for our applications. Their experience and methodical attention to detail mean the outcomes we achieve support our testing requirements.

Dr Andrew Johnson, Assistant Director, RandA

Optimax are a trusted partner! We have been working in partnership with Optimax for several years, to supply us with inspection solutions, service, and onsite calibration to UKAS standards. Their knowledge and expertise is exceptional, they provide honest, independent advice. Optimax are quick to provide options and solutions for our inspection requirements. They work hard to deliver a solution that 100% fits the application rather than just supplying a product. Optimax work with us to ensure we achieve our inspection objectives – they are one of the first companies I turn to.

Bruce Daggett, Senior Aerospace Weston, Inspection Team Leader

For over 14 years Optimax has been providing us with inspection equipment, service and most importantly expertise. We need suppliers that can go the extra mile in looking specifically at our application and then providing a suitable and sometimes bespoke solution, and this is where Optimax have really made a difference

John Harris, Director, Nevo Developments

Optimax have an extensive product range that was very attractive to us. They took the time to understand my requirements and align a solution that fitted into my manufacturing processes. They were very knowledgeable and friendly, I found the virtual demonstration extremely helpful. The outcome of the project has been very successful and performs above expectations. I would definitely recommend Optimax.
