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.

The thermal deformation of gray cast iron is much lower than other materials. For example, the contact surface of the base and the upper surface of the vertical car must be manually scraped. If it is cast steel or wrought iron, it cannot be manually scraped.

Cast iron base plate, test bench plate is the large base plate of the test bench for testing the running-in, loading, vibration, and fatigue performance of the automobile, reducer, gearbox, motor and other scientific research institutes and production unit laboratories during the product bench test.
