What items need to be checked for unpacking and acceptance of newly purchased cast iron fixed plates?

The primary task for unboxing and accepting new cast iron fixed plates is to verify the vouchers and visually inspect them. Carefully compare the purchase contract to confirm whether the specifications, accuracy levels (such as 00 level, 1 level), and material standards of the ordered plate are consistent. Subsequently, a comprehensive visual inspection will be carried out to check for any obvious bumps, cracks, sand holes, or rust caused during transportation, and to inspect the details such as T-slots and lifting holes for completeness.

The core step is to conduct preliminary verification of key dimensions and accuracy. Use qualified measuring tools to measure the main external dimensions and diagonal length of the fixed plate, and confirm that they are within the tolerance range. The most crucial thing is to use professional tools such as a level or laser interferometer to conduct a preliminary inspection of the flatness of its working surface, compare the results with the data on the factory certificate, and determine whether it meets the promised accuracy level.

Finally, verify the integrity of the accompanying documents and accessories. Ensure that the factory certificate of conformity, inspection report, user manual and other documents are complete. Simultaneously check all accompanying accessories, such as anchor bolts, adjusting shims, special tools, etc., to ensure they are intact and complete. After completing the above checks and recording all results, sign to confirm acceptance. If there is any dispute, immediately communicate with the supplier.
