Comprehensive Technical Transformation to Improve the Efficiency of CNC Vertical Lathe
Aiming at the common problems in the application of existing CNC vertical lathes, through research on key technologies to improve the efficiency of CNC machining, such as tapping the potential of CNC equipment, exerting the performance of machine tools, increasing the existing limited cutting time ratio, improving products and testing Efficiency, etc., give a very effective implementation plan for improving its processing efficiency.
Optimizing process plan
(1) Reasonably set the rough turning machining dimensional tolerance and allowance.
(2) Concentrate the process according to the principle of equipment efficiency.
(3) Improve the clamping positioning structure and increase the rigidity of the processing system.
The automatic compensation technology of CNC vertical lathe on-line measurement is to use the measurement and cutting function of the machine tool to realize the measurement of the machining error or the tool yield, and automatically compensate the machining tool compensation to avoid the out of tolerance or scrapping of the machined parts caused by the artificial calculation of the tool compensation value. . The movement process of the machine tool with this function is as follows: the machining allowance of the part is processed in two times. For example, leave a 0.6mm allowance on the surface of the part, first use the turning tool to turn off the 0.3mm allowance, and then return the tool to the tool magazine and adjust it through the program. Take out the measuring head and measure the deviation between the machining size of the machined part and the programmed value according to the measurement program. The machine tool automatically calculates the tool deviation value, returns the probe to the tool magazine, and then recalls the previous turning tool, and at the same time performs online measurement and calculation The tool compensation value input is called out of the tool wear, and the compensated tool is used to process the remaining 0.3mm margin. The entire processing process is called online measurement and automatic compensation cutting.
The efficiency and potential of CNC machine tools are greatly improved, which can effectively solve the common problem of insufficient effectiveness of CNC vertical lathe equipment. Through rapid positioning fixtures, high-efficiency testing and other aspects of application research, the utilization rate and production efficiency of CNC equipment are greatly improved, the quality of CNC machining products is guaranteed, the production cost is reduced, the machining cycle is shortened, and the improvement of CNC is explored. The realization mode of machining efficiency has very high practical value and promotion significance for improving the economic benefits of CNC machining in the industry.
