For Sandblasting barrel parts with complex shapes, the realization of its processing technology is a systematic and delicate process, involving the comprehensive application of multiple advanced processing methods and technologies.
First, advanced modeling technology is often used in the initial stage of manufacturing. Computer-aided design (CAD) software is used to accurately draw a three-dimensional model of the part, which presents every detail of the complex shape in detail, including curved surfaces, grooves, holes, etc. Through the CAD model, the part can be virtually analyzed to evaluate the processing difficulty and possible problems in advance, such as stress concentration points and material removal rate.
In actual processing, for some parts with complex internal structures, casting technology may be used. By making a high-precision mold, liquid metal is poured into it and waited for it to solidify and form. During the casting process, parameters such as mold temperature, pouring speed and pressure need to be strictly controlled to ensure the integrity of the internal structure of the part and the accuracy of the shape. For example, for Sandblasting barrel parts with fine internal flow channels, a suitable casting process can form these complex channels in one go.
For the external complex curved surfaces and high-precision dimensions of the parts, numerical control processing technology (CNC) plays a key role. Multi-axis CNC machine tools can accurately cut parts according to preset programs. When processing complex curved surfaces, complex tool path planning is used to move the tool in multiple directions to gradually process the parts to the designed size. At the same time, in order to ensure the processing accuracy, high-precision measuring instruments are used to measure and feedback the parts in real time so that the processing parameters can be adjusted.
In addition, electrospark machining (EDM) is very effective in processing some parts with high hardness and complex shapes. For example, for cavities with deep holes, narrow grooves or complex shapes, EDM uses pulse discharge between the electrode and the workpiece to erode the material, and can process shapes that are difficult to achieve with traditional cutting. Moreover, for some complex-shaped Sandblasting barrel parts that require extremely high surface quality, surface treatment processes such as grinding and polishing will be combined to further improve the quality of the parts and ensure their good performance in the sandblasting barrel. The comprehensive use of these processes realizes the processing process of complex-shaped Sandblasting barrel parts from design to finished products.
