The spliced cast iron plate (spliced platform) is suitable for larger size more than 4000X8000mm, because the area of a single piece is too large, and it is not easy to transport or install the platform.

The accessories for adjusting the balance of the machine tool include: leveling support, leveling frames, precision leveling pads, etc.

The size and shape of large-scale bed castings have good repeatability and have the characteristics of precision casting;

Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, and weight deviation of the casting; internal quality mainly refers to the chemical composition, physical properties...

The basic principle of cast iron plate base surface transformation is to characterize the translation or rotation or both of the reference plane with the increase or decrease of the original measurement data value.

1. The method of fixing the cast iron ground rail is to fix it firmly with M8 iron expansion nails or shooting nails according to the required distance (about 500-700mm) on both sides of the inner side of the track.
