The characteristics of CNC machine tools include high flexibility, high processing accuracy, high degree of automation, high productivity, and improved working conditions. The following is a detailed introduction to these characteristics:
High flexibility: CNC machine tools can adapt to a variety of processing objects, especially suitable for single-piece production of products such as molds, providing a suitable processing method for manufacturing. At the same time, CNC machine tools can change the type of processed parts by replacing the program, and are suitable for occasions where the processed parts are frequently changed, and are suitable for the production of small batches of products and the development of new products.
High processing accuracy: The processing accuracy of CNC machine tools can generally reach 0.05 - 0.1MM, and the positioning accuracy is relatively high. This is because CNC machine tools are controlled in the form of digital signals. For each pulse signal output by the CNC device, the moving part of the machine tool moves a pulse equivalent (generally 0.001MM), and the reverse clearance of the feed transmission chain of the machine tool and the average error of the screw pitch can be compensated by the CNC device.
High degree of automation: CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The range of spindle speed and feed rate is large, allowing the machine tool to perform powerful cutting with large cutting amounts. At the same time, CNC machine tools are entering the era of high-speed processing. The rapid movement and positioning of moving parts and high-speed cutting processing greatly improve productivity.
High productivity: CNC machine tools can effectively reduce the processing time and auxiliary time of parts. The range of spindle speed and feed rate of CNC machine tools is large, allowing the machine tool to perform powerful cutting with large cutting amounts. In addition, when used in conjunction with the tool magazine of the machining center, continuous processing of multiple processes on one machine tool can be realized, reducing the turnover time of semi-finished products between processes and improving productivity.
Improved working conditions: What the operator of a CNC machine tool needs to do is only the input and editing of the program, loading and unloading of parts, preparation of tools, observation of the processing status, inspection of parts, etc. The labor intensity is greatly reduced, and the labor of the machine tool operator tends to be intellectual work. At the same time, the machine tools are generally combined, which is both clean and safe.
In general, CNC machine tools have become indispensable and important equipment in modern manufacturing with their unique advantages such as high flexibility, high processing accuracy, and high degree of automation. With the continuous progress of technology and the in-depth application, CNC machine tools will play an important role in more fields and promote the manufacturing industry to develop in the direction of higher quality and higher efficiency.
