Compared with traditional machine tools, control machine tools have the following characteristics.
Processing parts on a CNC machine tool depends on the processing sequence. It is different from an ordinary machine tool. It does not need to be made, many molds and fixtures are changed, and there is no need to frequently adjust the machine tool. Therefore, CNC machine tools are used in places where the processed parts are frequently changed, which is suitable for the consumption of single-piece, small-batch products and the development of new products, thereby extending the production preparation cycle and saving a small amount of processing equipment costs.
The machining accuracy of CNC machine tools can be individually up to 0.05-0.1MM. CNC machine tools are controlled according to the digital signal situation. Each time a pulse signal is an output from the CNC installation, the moving parts of the machine tool move a pulse equivalent (individually 0.001MM), and the machine tool advances The uniform error between the backlash of the transmission chain and the screw pitch can be compensated by the CNC installation, so the positioning accuracy of the CNC machine tool is relatively high.
To process the same batch of parts, on the same machine tool, under the same processing conditions, using the same tools and processing sequence, the cutting paths of the tools are complete and the same, the parts have good consistency, and the quality is stable.
The CNC machine tool can effectively increase the processing time and auxiliary time of the parts. The large scale of the spindle sound speed and feed rate of the CNC machine tool allows the machine tool to perform powerful cutting with a large amount of cutting. CNC machine tools are currently entering a period of high-speed machining. The rapid movement and positioning of mobile parts of CNC machine tools and high-speed cutting have greatly increased the consumption rate. In addition, it can be used in conjunction with the tool magazine of the machining center to carry out the continuous processing of multiple processes on one machine tool, increasing the turnaround time of semi-finished products and improving the consumption rate.
Before CNC machine tool processing is adjusted, output sequence, and start, the machine tool can actively continue processing until the processing is completed. What the operator has to do is to perform tasks such as sequence output, compilation, part loading and unloading, tool preparation, machining status observation, and part testing. The rest intensity is greatly reduced, and the rest of the machine tool operator tends to be an intellectual task. In addition, machine tools are individually united, which is clean and safe.
