Our Comprehensive Calibration Process
Our specialists bring years of expertise to the calibration of your granite surface plates. The process includes:
Thorough Assessment - evaluating the current condition of your surface plate
Precision Measurement - using advanced equipment to identify deviations
Expert Hand-Lapping - carefully restoring the surface to original specifications
Final Verification - confirming the plate meets the required grade
Certification - providing UKAS-accredited documentation of compliance
Depending on the size of your plate and your workshop requirements, our calibration specialists can service plates on location or at our UKAS-accredited laboratory.
Why is Granite Surface Plate Calibration Important for Your Business?
Surface plates change over time. The more your granite surface plates are used, the more they change with wear and tear, making accurate measurement increasingly challenging. Regular calibration helps manage the effects of wear and optimises the longevity of your graded surface.
Regular scheduled specialised calibration of your surface plates and tables helps to:
Maintain measurement accuracy critical to your quality control
Extend the life of your valuable metrology equipment
Reduce errors and rework in your manufacturing processes
Meet quality assurance requirements and maintain compliance with industry standards
Protect your investment in precision measuring equipment
Maintaining Your Granite Surface Plates Between Calibrations
To protect your investment and extend the time between formal calibrations, we recommend these maintenance practices:
Only Use a Granite Surface Plate for Measurement
Your granite surface plate is a precision measuring tool. Using it for storage or resting food and drinks can cause wear and staining, which can lead to incorrect measurements. We recommend covering your surface plate when it is not in use to preserve its calibration and maintain measurement accuracy.
Use Different Parts of the Granite Surface Plate
Regularly changing the workpiece location helps distribute wear evenly across your surface plate. Our team can advise on rotation systems or specialised apparatus to safely move and position heavy plates.
Avoid Overloads or Scratches
Minimise impacts and spread loads over a wide area, not at a single point. Resting flat edges on the surface plate protects the material while stabilising the workpiece and maintaining your surface plate’s calibration.
