Today, I will introduce to you the characteristics of the processing technology of horizontal machining centers. Dabai Precision Machine Tool (Jiangsu Co., Ltd.) is a high-tech enterprise specializing in R&D, design, production and manufacturing of CNC machine tools and CNC machine tools.
- Detailed requirements for processing technology.
All process issues should be arranged in advance as much as possible and incorporated into the processing program. The processing technology not only includes detailed cutting processing steps and the clamping scheme of the tooling fixtures used, but also includes the model, specification, cutting amount, other special requirements of the tool, and the process diagram marked with the coordinate position of the CNC processing. - Strict requirements for CNC processing technology.
Comprehensive consideration must be given during the processing process to avoid serious consequences. For example, when tapping, the CNC machine tool does not know whether the hole is full of iron chips, whether it needs to be retracted to clean up the iron chips before continuing processing. When encountering this kind of situation, it is usually necessary to consider it in advance in the process and take a series of process measures to solve it. - To formulate CNC processing technology, mathematical processing of part graphics and calculation of programming dimension setting values are required.
The programming size is not the design size on the part drawing, and the part drawing needs to be mathematically processed and calculated. The programming dimension setting value must be readjusted and calculated according to the part size tolerance and the shape and geometry relationship of the part to determine the programming size. - Consider the influence of feed speed on part shape accuracy.
When selecting cutting parameters, the influence of feed speed on the accuracy of machined parts should be considered. In CNC machining, the moving trajectory of the tool is completed by interpolation operation. According to the interpolation principle, under the given conditions of the CNC system, the faster the feed speed, the lower the interpolation accuracy. - Analyze the importance of tool selection.
The machining programming of complex surfaces usually adopts automatic programming, with a central motion trajectory, so it has a tool compensation function, and the programmed program can only be pushed back and re-written. - Relatively concentrated machining procedures.
Since CNC machine tools, especially CNC machine tools with complex functions, are generally equipped with automatic tool changing devices, they can automatically change tools during machining, and multiple procedures or all procedures can be completed in one clamping. Therefore, the obvious feature of CNC machining technology is that the procedures are relatively concentrated, which is manifested in fewer procedures and more process content.
