Granite Surface Plate with Bench Centre
Dual-Purpose Precision Inspection System for High-Accuracy Measurement
Product Overview
SPT Metrology manufactures premium Granite Surface Plates with Bench Centre Attachments, designed as a versatile dual-purpose inspection system for high-precision measurement tasks. This innovative combination functions both as a high-grade granite surface table and a precision bench centre, allowing users to perform flatness inspection, layout marking, concentricity checking, parallelism testing, and true rotation measurement on a single compact platform. Engineered for performance and built to international standards, this product offers unmatched flexibility and accuracy in quality-control environments.
The granite surface plate is manufactured from high-density, naturally seasoned black granite, offering exceptional stability, rigidity, and resistance to wear, corrosion, and temperature variations. The plate complies with IS: 7327-2003 for granite surface plates, ensuring long-term accuracy and minimal deformation under continuous industrial use. Precision machining, lapping, and rigorous inspection ensure that the plate meets the highest accuracy grades required for metrology and inspection applications.
To enhance utility, the granite plate is equipped with metal inserts and T-slots, enabling secure mounting of fixtures, attachments, and bench centre components. This allows the equipment to be used both as a traditional surface plate and as a precision rotational inspection system. The bench centre attachment is manufactured according to IS: 5980 standards, ensuring reliable measurement of concentricity, runout, parallelism, and true rotational accuracy for shafts, mandrels, spindles, and cylindrical components.
The cast iron referencing and centre supports meet IS: 2285-2003, offering the strength, vibration damping, and structural rigidity necessary for accurate testing under load. Hardened and ground centres ensure smooth rotation of components while maintaining alignment throughout the inspection process. The combined system provides superior versatility, making it ideal for tool rooms, machine shops, R&D labs, calibration facilities, and precision engineering industries.
By integrating flatness inspection and rotational measurement into one unit, the Granite Surface Plate with Bench Centre significantly improves workflow efficiency, reduces workspace requirements, and eliminates the need for multiple inspection tools. This makes it a cost-effective, space-saving solution for industries seeking reliable, repeatable, and highly accurate inspection capabilities.
Choose SPT Metrology for precision-engineered inspection systems that deliver durability, accuracy, and long-lasting performance—crafted to meet the highest international metrology standards.
