CNC Spring End Grinding Machines Test accuracy
How to judge the accuracy of CNC spring end grinding machine
In particular, the primary requirement for large stiffness precision springs is the high precision of the device, the small load of the spring. Because of the small changes in displacement, it will cause a large change in the test force, and to ensure the test force of the test accuracy, it is easy to do, but to ensure that the spring test machine another parameter displacement accuracy, to ensure the accuracy of spring test key, But also to determine the accuracy of the spring test machine specifications.
Therefore, more and more users, the accuracy of the displacement test as a measure of the level of high and low standard test machine. CNC spring end grinding machine in the national norms, the displacement accuracy requirements are very low can not meet the requirements of large stiffness precision spring, therefore, for CNC spring end grinding machine manufacturers, the need to improve the accuracy of displacement testing to meet the requirements of users. There are many factors that affect the accuracy of the displacement test, such as the detection method, the whole structure, the machine stiffness, the parallelism of the pressure plate, the measurement components, the data, the load displacement sink, etc. As long as these factors are overcome, the guarantee of the displacement precision is not questionable.
To ensure that the test force in the full range, the spring test machine is strictly in accordance with the norms of the displacement detection to ensure that the spring placed in different places in the pressure plate test force is basically the same. Any load will not cause the displacement of the load sensor sink. In addition, the spring test machine loading method on the impact of the test results can not be ignored The early loading method is mainly for ordinary AC motor drive system load, loading speed can not be adjusted, for spring and other elastic components, due to rebound stress There is a rapid compression of the data automatically collected and slow compression or static compression of the collected data is very different, and now more use of variable speed systems such as AC servo speed control system, through the realistic simulation of the working state of the spring, the real measure of the spring in this state Under the internal stress, to provide the basis for the spring design.
CNC spring end grinder function is relatively simple shortcomings have been improved by the computer, with the development of computer technology. Intelligent function set expert system, parameter selection, database, clear window Chinese interface, simple mouse operation, so that the spring test the process of the most ideal state possible, intelligent level has been greatly improved, the operator as long as gently Click the mouse, you can follow the pre-set any mode of measurement, control, by setting a different test speed, the test process parameters, so that the test mode, the entire test process can be controlled in accordance with people's will, test curve and test data in real time Display, test data can also be calculated according to industry norms or corporate norms, finishing, output, but also on the previous test process, test results for inquiries, powerful computing and mathematical statistics function instead of the past complicated work, greatly reducing the people The amount of labor.
The application of computer technology, in addition. (Referred to as the lower computer) and the calculation center of the host computer (referred to as the host computer) together to achieve the test data transmission, disposal, integrated management, the central laboratory, by the host computer to the next crew to achieve integrated management The.
