QUALITY ASSURANCE STARTS WITH THE CALIBRATION OF SURFACE PLATES
Surface plates are the basis of high precision measurements in production as well as in laboratory areas. Often this fact is not sufficiently taken into account and the surface plates do not show the surface quality required for the measuring precision expected. Frequently the granite surface plates are locally worn and falsify thus the measuring results.
This uncertainty can be eliminated by a periodic calibration of the surface plate and corrections where necessary. Most quali-ty certificates require imperatively a valid calibration certificate of the measuring equipment used, in order to be accepted.
WYLER SWITZERLAND, traditionally specialized in the field of flatness measurements, can offer a very competent calibration service. Accredited as a calibration laboratory SCS since 1993, WYLER SWITZERLAND assures a professional calibration service for straightness, flatness and rectangularity.
The measurement / calibration as well as a possible reconditioning are executed by well trained staff using high quality measuring instruments and software according to accredited procedures (based on ISO 1101).
These services are made at the WYLER factory under ideal conditions. On special request, particularly for very large objects or for a large number of objects, on-site service can be provided. The calibration is done accord-ing to the requirements specified in our SCS accreditation, or according to special WYLER procedures for non-accredited measurements.
Internal calibration service
This service takes place in our factory in Winterthur.
The measuring and control plates as well as setting squares are measured according to our accreditation under defined environmental conditions, lapped if necessary and an SCS certificate is issued on request. This service is recommended for individual measuring and control plates up to a size of 1200mm x 800mm.
External calibration service
This service is only available in Switzerland and the Principality of Lichtenstein.
For larger measuring and control plates or for simultaneous calibration of several measuring and control plates, we offer a calibration service and rework on site.
Since our internal accredited environmental conditions cannot be reproduced at customer's site, we issue a measurement certificate in this case.
