1) Shaking out: The measuring tool castings can be squeezed out after being fully cooled, and the general requirement is not less than 3 hours. If the time is too short, surface chilling will occur and the hardness will be higher and cutting will be difficult. When the measuring tool casting is large, thermal cracking may occur, and the internal stress of the measuring tool casting is relatively large, which is easy to cause deformation and affect the overall size of the measuring tool casting.

2) Sand cleaning: For measuring tool castings to obtain castings with good surface finish, small parts can be cleaned by drums to remove the sand on the surface. The large parts are shot blasted to remove the sand on the surface. The sticky sand on the non-processed surface is cleaned up to prevent it from entering the bearing chamber after it falls off when it is loaded into the finished product and moves, and the use of the bearing will cause adverse effects.

3) Aging treatment: General measuring tool castings for measuring tool castings must be aging treatment to reduce the internal stress of measuring tool castings and obtain good performance.

4) Control of the inspection process: Through inspection, feedback the defects of measuring tool castings, find and analyze the reasons, and take timely measures to reduce the occurrence of defects of measuring tool castings.

Through the control of the above controls, the measuring tool castings become qualified products, and each process is required to cooperate and coordinate with each other. Only by paying attention to details can the quality of each process be better controlled and improved, and the quality of the cast iron machine table castings can be guaranteed.
