What are the processing characteristics of horizontal machining centers?

Today, what are the processing characteristics of horizontal machining centers? Dabai Precision Machine Tool (Jiangsu Co., Ltd.) is a high-tech enterprise specializing in research and development, design, production, and manufacturing of CNC machine tools and CNC tool machines.

1. Detailed requirements for processing technology content

All process issues should be arranged in advance and included in the processing program as much as possible. The machining process not only includes detailed cutting steps and the clamping scheme of the used fixtures, but also includes the model, specification, cutting amount, other special requirements of the cutting tool, as well as the process diagram marked with CNC machining coordinate positions.

2. Strict requirements for CNC machining process

During the processing process, comprehensive consideration must be taken to avoid serious consequences. When tapping threads, the CNC machine tool does not know whether the hole is filled with iron filings, and whether it is necessary to retract the tool to clean the iron filings before continuing processing. When encountering a situation, it is usually necessary to consider it in advance in the process and take a series of process measures to solve it.

3. Developing CNC machining processes requires mathematical processing of part graphics and calculation of programmed size settings

Programming dimensions are not the design dimensions on the part drawing, but require mathematical processing and calculation of the part drawing. The programming size setting value needs to be recalculated based on the geometric relationship between the part size and the shape of the part, in order to determine the programming size.

4. Considering the influence of feed speed on the shape accuracy of parts

When selecting the cutting amount, it is necessary to consider the influence of feed speed on the accuracy of the machined parts. In CNC machining, the movement trajectory of the tool is completed by interpolation operations. According to the interpolation principle, under the predetermined conditions of the CNC system, the faster the feed speed, the lower the interpolation accuracy,.

5. The importance of analyzing tool selection

Complex surface machining programming usually adopts automatic programming method, with a central motion trajectory. Therefore, with tool compensation function, the programmed program can only be reversed and restarted.

6. Relatively concentrated processing processes

Due to the fact that CNC machine tools, especially those with complex functions, are generally equipped with automatic tool changing devices, they can automatically change tools during the machining process, and multiple or all processes can be completed with one clamping operation. So, the obvious characteristic of CNC machining technology is the relatively concentrated process, manifested as fewer days of process and more content of process.
