Functional characteristics of machine tool castings
2023-01-02
Compared with the traditional sand casting process, the casting of Large Castings such as machine tool bed can not only save expensive wood costs, but also operate more conveniently, which greatly improve the production efficiency. Machine tool bed Castings are also very convenient in use. It needs regular verification and maintenance, long-term use of precision measuring tools, but also need to be regularly sent to the metering station for maintenance and precision testing, to prevent product quality problems caused by the measurement error. Although the accuracy of the surface Rockwell hardness tester is not higher than that of the Vickers hardness tester, it is sufficient to meet the requirements as a testing method for quality management and qualified inspection in heat treatment plants. What's more, the machine bed castings have the advantages of simple operation, convenient use, low price, rapid measurement, and direct reading of the hardness value, which makes the machine stable on the ground. The surface Rockwell hardness tester can be used to treat batches of surfaces. The heat-treated workpieces are tested quickly and non-destructive. This is of great significance for metal processing and machinery manufacturing plants. As a large casting, the machine bed casting also needs heat treatment to improve its own performance.
