Cast iron plate is an important tool used in machinery manufacturing plants for measurement, inspection, marking and fitter assembly.

Although the cast iron platform and the cast steel platform are both iron-carbon alloys, due to the different percentages of chemical elements such as carbon, silicon, manganese, phosphorus, and sulfur, they have different metallographic structures after crystallization, and show mechanical properties.

1. Due to the use of a foamed plastic pattern that vaporizes when it encounters molten metal, there is no need for mold release, no parting surface, no core, so there is no flash burr, and the dimensional accuracy and surface roughness of cast iron platform castings are close to investment casting.

There are many reasons for the error of the cast iron platform in the machining process, such as the problem of the workpiece itself or the problem of the machine tool. In the following, we will introduce the causes of errors in cast iron platform planing from three main aspects.

The special platform for motor performance test is also called cast iron platform, motor test bench, T-slot motor test platform, and motor test workbench.

1. Design craftsmanship of castings. When designing, in addition to determining the geometry and size of the casting according to the working conditions and the properties of the metal material
