What are the processes for inspecting machine tool castings

Machine Tool CastingsThe market competition is fierce, which is not only a competition for quality, but also a competition for delivery time. The straightness of the machine tool bed is the fundamental accuracy of the machine tool. In the consumption of machine tools, the bed is the fundamental component, and the assembly process is completed on the bed. If the consumption does not produce qualified bed bodies, other consumption processes cannot be stopped. The long consumption cycle of castings is an important factor affecting the consumption cycle of machine tools. The residual stress of castings is a hot issue that the machine tool manufacturing industry pays attention to in order to maintain the stability of casting accuracy. The methods for casting stress can be summarized as natural aging method, vibration aging method, and thermal aging method. Choosing the appropriate stress process method is very important for accelerating enterprise consumption." Important role. Based on this application, harmonic vibration 1. Introduction to residual stress. During the solidification and cooling process of cast iron castings cast at high temperatures, shrinkage and phase change occur due to temperature drop. If shrinkage and phase change are obstructed, casting stress will be generated in the castings. Casting stress can be divided into three types according to its composition: thermal stress, phase change stress, and mechanical barrier stress. Casting stress is the sum of thermal stress, phase transformation stress, and mechanical stress
