The scraping of the cast iron platform is divided into rough scraping, fine scraping and finest scraping.

1. Cast iron platform blank: make drawings according to technical requirements, make wood or foam shapes according to drawings, batching, modeling, drying, casting, sand falling, cleaning and inspection of various parts of the blank.

1. In order to prevent the deformation of the cast iron T-slot platform, when hoisting the cast iron T-slot platform, four steel wire ropes of the same length should be used to hang the four lifting holes on the cast iron slab. At the same time, stabilize the cast iron T-slot platform hoisting on the transportation tool.

If there is sand hole on the surface of the cast iron floor plate, according to the regulations, if the size of the hole does not exceed 0.5 mm, normal use will not be affected. If the sand hole is large, the cast iron workbench will be repaired during processing.

The accuracy of the cast iron assembly plate is mainly the smoothness and flatness, and the cast iron platform will inaccurate if it is rusted and used for a long time.

The advantages of using clamping rails, T-slot clamping rails, ground beams, ground trough irons, and foundation trough irons: In this way, there is no need to make a large platform, which not only saves material costs, but also takes up a small space. It can be said to be very cost-effective.
