High-precision cast iron base table need to be manufactured by manual scraping. The cast iron plate is manually scraped after being machined by the machine tool. The purpose is to reduce the surface roughness value, improve the contact accuracy and geometric accuracy, thereby improving the machine tool's mating rigidity, lubrication performance, mechanical benefit and service life. It is also only a surface grinder. And the processing technology of the machine tool equipment and the cast iron plate is difficult to achieve with the guide rail grinding machine.

The scraping process of cast iron base table is a combination of scraping and grinding. Plane scraping is to grind the surface of the scraping platform by the corresponding grinding tool. After grinding, the scraping shows the contact point, reciprocating, alternating cycles, and continuous operation. The surface roughness value and shape and position error of the cast iron platform are gradually reduced; the contact accuracy and geometric accuracy are gradually improved during operation until the specified requirements are met.

The scraping process of the cast iron base table requires mixing and stirring of red iron powder with diesel or kerosene, and then dripping the color paste onto the surface of the cast iron plate and scouring evenly with cotton yarn. All black spots, black spots are divided into bright spots, thick black spots, and light black spots. These black spots are a variable in scraping. After continuous alternating cycles of continuous operation and continuous scraping, the black spots become dense, from uneven distribution to uniform distribution. The evolution of black spots is also a process of gradual improvement in surface finish, surface contact accuracy, and surface geometric accuracy.
