Granite Surface Plates according to DIN 876 | ULTRA Shop

Buy ULTRA granite surface plates (natural hard stone) according to DIN 876 in grade 0, grade 00, or grade 000 for maximum flatness. Available with cabinet, support stand & calibration certificate.

Granite surface plates from ULTRA Germany represent the highest precision and dimensional stability in industrial metrology. Manufactured from the finest granite with a homogeneous structure, they exceed the requirements of DIN 876. They are ideally suited for reliable use in measuring rooms, production areas, and testing laboratories.

Diamond-Lapped Precision for Demanding Industrial Environments

The measuring surfaces of each granite surface plate are diamond-lapped. This ensures permanently high flatness as well as a wear-resistant, corrosion-proof, and acid-resistant surface. Thanks to the extreme thermal and dimensional stability of the natural hard stone, accuracy is fully maintained even during temperature fluctuations in operation.

Custom Modifications: Threaded Inserts & T-Slot Rails

Maximum flexibility for your measuring fixtures: We are able to integrate custom modifications into almost all surface plate sizes. The matching accessories can be configured directly on the respective product page:

• Precise Guide and Clamping T-Slots: For a secure and stable clamping of tailstocks, roller blocks, or other measuring components.
• Robust Threaded Inserts: High-strength inserts in various thread sizes for rigid fixation of your testing setups.

Certified Quality & Custom Construction

• Accuracy Grades for Every Requirement: Choose between grade 000 and grade 00 for maximum precision in climate-controlled measuring rooms, or grade 0 for direct use on the shop floor.
• Guaranteed Traceability: Final processing is carried out under strictly controlled climate conditions. Each precision surface plate is individually tested and delivered including a calibration certificate.
• Optimal Weight Distribution: The design incorporates the physical Bessel points to effectively minimize deflection during 3-point support.

Ergonomics and Accessories for Daily Work

The surface plates are flexibly configurable: Choose a stable cabinet base including a practical drawer module or a robust support stand. Height-adjustable leveling feet and integrated anti-tilt protection ensure an absolutely secure, low-vibration, and ergonomic application in your quality assurance.
