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.

Cast iron slab should be based on the quality of castings when selecting the pouring position. Generally speaking, the following principles should be paid attention to:

The base plate of the dynamometer is also called the testing plate of the dynamometer. It is the basic cast iron plate and an important part of the dynamometer. The dynamometer is mainly used to test the power of the engine.

The design of the base drawing of the motor test bench should be designed according to customer needs. According to the welding platform standard GB/T22095-2008, it mainly includes external dimensions, load-bearing size, working surface t-slot size, working surface accuracy, etc.

Scraping is one of the methods of flat surface finishing of round cast iron platform. It is to reduce the surface roughness value, improve the contact accuracy and geometric accuracy, thereby improving the mating rigidity, lubrication performance, mechanical efficiency and service life of the machine tool.
