More questions buyers ask
What is a granite surface plate used for?
Granite surface plates are used as a reference plane for precision inspection, layout work, and calibration of measuring instruments in quality control.
Why choose granite over cast iron for surface plates?
Granite offers superior thermal stability, corrosion resistance, and does not develop burrs if scratched, making it ideal for precision metrology.
What does O Grade accuracy mean?
O Grade is a high-precision accuracy standard for granite surface plates, ensuring extreme flatness required for laboratory and precision workshop tasks.
How do I maintain my Luthra granite surface plate?
Keep the surface clean, avoid dropping heavy objects, use protective covers, and periodically check flatness to ensure long-term accuracy.
Are Luthra surface plates suitable for workshop environments?
Yes, they are designed to withstand workshop conditions while providing the stability needed for accurate measurement and marking.
Can I mount gauges on this granite plate?
Yes, the dense, stable surface of Luthra granite plates is perfect for mounting mechanical gauging systems and height gauges.
Does the plate come with a stand?
Many Luthra granite surface plates are available with sturdy metal fabricated stands to provide a stable working height of 900mm.
How is the flatness of the plate measured?
Flatness is measured using precision electronic levels or autocollimators to ensure it meets the specified O Grade tolerances.
Is natural granite affected by temperature changes?
Natural granite has low thermal expansion, providing excellent stability even in environments with minor temperature fluctuations.
Do you provide GST invoices for these plates?
Yes, all purchases include a valid GST invoice for business accounting purposes.
Who should choose the 300x300x50mm Luthra Granite Surface Plate?
This compact size is ideal for small-scale inspection, benchtop layout work, and precision tasks in space-constrained workshops.
Who should choose the 2000x1000x200mm Luthra Granite Surface Plate?
This large-format plate is best suited for heavy-duty industrial inspection, large component assembly, and high-volume quality control labs.
How does the 300x300mm plate compare to the 630x630mm model?
The 300x300mm is for small, portable tasks, while the 630x630mm offers a larger surface area for medium-sized components and more complex layout work.
Is the 1000x630mm plate better than the 900x600mm for general use?
The 1000x630mm provides slightly more surface area and depth, offering better stability for larger parts compared to the 900x600mm model.
