RIGOROUS CHECKS NECESSARY

In many industries like ours, the need for control and precision is of the utmost importance. Small particles of dirt or a few thousandths of a millimetre margin of error can be devastating for both our own activities as well as for customers and end customers. That is why our quality control is so rigorous for purity in components, oils and cutting liquids, as well as tolerances in dimensions. In our company we have several machines that have the sole task of analysing particles and rejecting parts that do not comply with the specifications set up by the customer. These are also services we offer to the market, with our tried and tested control stations, measuring instruments and laboratory.

Sorting machines are important in our activities. That is why we only use the best. One of them photographs products, counts the pixels and rejects any defective units. Another photographs and ensures that every individual product is free from shavings. It also rejects any that deviate from the limits.

WHY MAKE CLEANLINESS ANALYSES?

Requirements on the cleanliness of components are increasing all the time. The reason is to minimise the risk of breakdowns, reduced efficiency or shorter life-spans. Cleanliness measurements are made to determine the quantity of dirt which the parts (surface), oils, liquid cleaners or systems contain.
How is the analysis carried out? There are several ways to measure cleanliness. Which method is used depends on the conditions for obtaining the most certain result possible. Analyses are often made in a series of tests on 3 to 5 samples. The parts are washed in different ways – rinsing, shaking or ultrasound cleaning – depending on the methods’ suitability for removing particles. The particles are then counted or a gravimetric analysis is made, as well as a simple observation of particles in a light microscope.

 

DOCUMENTS FOR THE FUTURE

After measurements are completed, the results are analysed. In the report compiled on behalf of the customer, the approach is described as well as information on the number of particles, the ISO class, images of the largest particles and other relevant particles. If necessary, our analysts make comments on the results and provide advice.

 

MEASUREMENT WITH PERFECT PRECISION

Error margins for precision components are minimal, with tolerances down to thousandths of a millimetre. In order to quality assure our own production as well as offering measurement as a service, we have a number of control stations.

 

WE MEASURE EVERYTHING

In addition to vernier callipers, micrometers and dial gauges, we also use some very advanced machines. Roundness meters, surface meters, contour meters, profile meters and microscopes are some examples. Another is the coordinate measurement machine that detects contours and observes any deviations outside set tolerances. To control and facilitate the processes in the measuring machines we use Mitutoyo Cosmos, a computerised system with Statistical Process Control.
