Import Granite Measurements -Vk-5701 Surface Plates — Buy in Bulk from Supplier in Taiwan

Jacob Iron Works Co., Ltd supplies the VK‑5701 granite surface plates, precision‑ground tools used as reference surfaces in dimensional inspection. Each plate is fabricated from A2 grade granite, a material selected for its low thermal expansion and dimensional stability. The plates are manufactured to meet German DIN flatness standards, providing traceability for high‑accuracy measurements.

Standard dimensions include 300 × 300 mm, 600 × 600 mm and 900 × 900 mm, with a typical thickness of 50 mm. Flatness tolerance is commonly specified as 0.5 µm per metre, and the surface finish is ground to a Ra ≤ 0.4 µm roughness. The granite grade conforms to ASTM C615 Class A2, ensuring consistent hardness and wear resistance. Each plate undergoes laser interferometry verification to confirm flatness within the declared tolerance.

Metrology labs, calibration workshops and manufacturing quality‑control departments rely on these plates for equipment calibration and part inspection. The supplier offers FOB and CIF shipping, and MOQ details are handled directly with the sales office. Prospective buyers should request the calibration certificate and the DIN traceability report before confirming the order. Payment terms and lead time are negotiated per contract and must be clarified during the quotation process.
