The dimensional accuracy of machine tool castings depends on the strict degree of process design and process control. The higher the dimensional accuracy of castings, the stricter the control of factors, and the correspondingly higher casting production costs. There are scientific standards to coordinate the requirements of both the supplier and the demander.

Cast iron plate accuracy: According to the standard metrological verification procedures, there are four levels of 0, 1, 2, and 3. The material is high-strength cast iron HT200-300. The hardness of the working surface is HB170-240.

The adjustable cast iron pad has two adjusting pad irons (two-layer adjusting pad iron) and three adjusting pad irons (three-layer adjusting pad iron). The horns are brought from random beds, and their standards and quantities are described by the equipment manufacturer.

The magnetic V-shaped block is easy to use, and the parts cannot be disassembled arbitrarily, so as not to reduce the magnetic force and affect the service life.

During the production process of cast iron floor plates, there will be a part of the deviation of the theoretical weight. It should be noted that the deviation of the cast iron floor plates will affect its usage.

The cast iron measuring platform is used for power experiments of machinery and engines, equipment debugging, and has good plane stability and toughness. The surface has a T-shaped groove, which can be used to fix the experimental equipment.
