Maintenance, Certification and Calibration Services
In order to
achieve the highest accuracy of your system and maximize
its productivity, we
highly recommend that your coordinate measuring
machine should only be serviced by
OEM trained specialists. Our service engineers
are former Leitz and Brown & Sharpe®
employees with an unmatched
level of OEM training. All our calibration & certification
services include a comprehensive maintenance.
We also offer repair service, when
needed, to meet the OEM specifications. Maintenance
contracts are also available.
CMM Calibrations/Certifications of your Company's CMM Include:
Calibrations performed to OEM and ISO
10360 and VDI/VDE 2617 specifications.
Report (15+ pages) on work performed, incl. before &
after correction results
Calibrations/Certifications performed in accordance
with industry standards
NIST traceable calibration/confirmation certificate
- CMM lab and temperature sensor accuracy check
- Probe System, reliability and repeatability
- Angular and straightness error corrections,
- Linear accuracy checks and corrections in X,
Y and Z axis
- Squareness checks and corrections in XY, XZ
- Volumetric (3 dimensional) measurements in 4
All reference artifacts are traceable
to the National or International Standards (NIST/ NPL).
CMM Calibration Examples
- Before & After
Example - Before Correction:
Measured on 1000mm KOBA step gage, steps measured at 40mm increments.
Range between upper and lower green Lines indicates maximum OEM allowed tolerance range (in microns),
center line indicates absolute 0 deviation. Maximum allowed tolerance range is 0.9+L/500 (+/- 2.9 microns at
distance of 1000mm). Red dots show the measured positions on the step gage, points lie within +1.5 microns
and -1.2 microns, some of the measured positions exceed the maximum allowed tolerance.
Example - After Correction:
Verified on 1000mm step gage now at 20mm increments to include possible Probehead
offset error. All points lie within +0.30 microns and -0.15 microns. Our service engineer was able to adjust the CMM
geometry to utilize less than 25% of the maximum OEM allowed tolerance.
Example Spatial Measurement:
This is an example that shows the results of 1 of the 4 spatial measurements.
Volumetric measurements in the 4 spatial positions combine all 21 possible accuracy deviations your CMM, such
as linear, angularity, pitch, yaw, roll and straightness deviations. These last 4 spatial measurements will only
indicate the combined errors of all these deviations, they can not be adjusted by the service engineer anymore.
The allowed OEM tolerance in this example is 1.2+L/400(+/ - 3.7 microns at distance of 1000mm).
All measured positions lie within +0.55 microns and -0.80 microns.
Our service engineer adjusted the entire CMM geometry to be within less than 35% of the max. allowed tolerance.
