The Cast Machine Tool Bases is made of HT300 material, with resin sand casting process and induction furnace melting process using all scrap steel and carbon additive, effectively ensuring the strength, hardness, and stiffness requirements of the machine tool. A CNC machine tool consists of a base, a screw guide rail, a worktable, a column, a machine head, etc. The Cast Machine Tool Bases mainly serves as a support, and is equipped with a worktable, spindle box, column, system, etc. The base is the foundation of the machine tool.

The weight and size range of Cast Machine Tool Basess are relatively wide, with lengths ranging from a few millimeters to tens of meters, which can meet the usage requirements of different industrial sectors; The quality of castings includes appearance quality, internal quality, and usage quality. Appearance quality refers to the surface roughness, surface defects, dimensional deviation, shape deviation, and weight deviation of castings; Internal quality refers to the chemical composition, physical properties, mechanical properties, metallographic structure, as well as the presence of pores, cracks, inclusions, segregation, and other conditions inside the casting. The quality of use refers to the durability of castings under different conditions, including wear resistance, corrosion resistance, cold and heat resistance, shock absorption, fatigue performance, as well as machinability, weldability and other process properties.

Quality of Cast Machine Tool Bases castings:

Mainly including appearance quality, internal quality, and usage quality. The appearance quality of cast iron platforms refers to the surface roughness, surface defects, dimensional deviation, shape deviation, and weight deviation of Cast Machine Tool Bases castings; Internal quality mainly refers to the chemical composition, physical properties, mechanical properties, metallographic structure, as well as the presence of holes, cracks, inclusions, segregation, and other conditions inside the casting of the Cast Machine Tool Bases; The quality of use refers to the working durability of Cast Machine Tool Bases castings under different conditions, including wear resistance, corrosion resistance, cold and heat resistance, fatigue, shock absorption, as well as machinability, weldability and other process properties. The quality of Cast Machine Tool Bases castings has a significant impact on the performance of mechanical products. The wear resistance and dimensional stability of cast iron flat Cast Machine Tool Bases castings directly affect the accuracy and service life of the Cast Machine Tool Bases.

Factors affecting the quality of Cast Machine Tool Bases castings:

1. Design processability of Cast Machine Tool Bases castings. When designing, in addition to determining the geometric shape and size of the Cast Machine Tool Bases casting based on working conditions and metal material properties, the rationality of the design must also be considered from the perspective of casting alloy and casting process characteristics, that is, obvious size effects and solidification, shrinkage, stress and other issues. The marking platform is used to avoid or reduce the occurrence of component segregation, deformation, cracking and other defects in the Cast Machine Tool Bases casting.

2. There should be a reasonable casting process. Based on the structure of the Cast Machine Tool Bases casting, the weight and size of the three-dimensional flexible welding platform, the characteristics of the casting alloy, and the production conditions, suitable parting surfaces, shapes, and core making methods are selected, and casting bars, cold iron, risers, and pouring systems are reasonably set. To ensure the acquisition of high-quality Cast Machine Tool Bases castings.

3. The quality of raw materials used for casting. The quality of metal furnace materials, refractory materials, fuels, fluxes, modifiers, as well as casting sand, sand binders, coatings, and other materials that do not meet standards can cause defects such as porosity, pinholes, slag inclusion, and sand adhesion in castings, affecting the appearance and internal quality of Cast Machine Tool Bases castings. In severe cases, it can lead to the scrapping of Cast Machine Tool Bases castings.

4. Process operation requires the development of reasonable process operation procedures, and the riveting and welding platform should improve the technical level of workers to ensure the correct implementation of process procedures.

Quality control and inspection of Cast Machine Tool Bases castings:

In casting production, the quality of Cast Machine Tool Bases castings should be evaluated. Firstly, it is necessary to establish process guidelines and technical conditions for the control and inspection of raw materials, auxiliary materials, and each specific product. Strictly control and inspect each process according to the process rules and technical conditions. Conduct quality inspection on the finished Cast Machine Tool Bases afterwards. Reasonable testing methods and appropriate testing personnel should be equipped. Generally, the appearance quality of Cast Machine Tool Bases castings can be judged by comparing sample blocks to determine the surface roughness of Cast Machine Tool Bases castings; Minor cracks on the surface can be inspected by coloring and magnetic particle methods. The internal quality of Cast Machine Tool Bases castings can be inspected and judged using methods such as audio, ultrasound, eddy current, X-ray, and gamma ray.
