Ball bar test machine accuracy

The CNC machine tool of the engraving machine integrates the automation technology, servo drive, precision measurement and precision engraving machine. The CNC machine tool integrates the technical achievements in various fields such as automation technology, servo drive, precision measurement and precision machinery, along with CNC technology and CNC machine tools. Development, the accuracy of CNC machine tools is an important indicator of the performance of machine tools, and it has become the main factor affecting the machining of workpieces. In order to improve the processing advantages of CNC machine tools, it is necessary to quickly identify and accurately correct the errors and improve the accuracy of CNC machine tools. . At present, the traditional method for precision detection of CNC machine tools is difficult to analyze the source of CNC machine tool error, and the commissioning cycle is long, which seriously affects machine tool productivity and production quality. The ballbar instrument is the most effective tool for comprehensive error parameter measurement, which solves this problem well.
1 The working principle of the ball bar is mainly composed of instrument sensor, magnetic cup, magnetic center frame, ball joint, magnetic tool cup, club transfer, etc., due to the inherent characteristics have been recognized by the majority of users. The ballbar instrument can quickly and conveniently and economically evaluate and diagnose the precision of CNC machine tools. It is suitable for various vertical horizontal machining centers and CNC lathes. It has the characteristics of simple operation and convenient carrying. The main working principle is to fix the precision sphere at both ends of the ballbar with one end fixed on the basic workbench by magnet, the other end is fixed on the machine main shaft, and then measure the circular trajectory formed by the two-axis differential compensation motion.
2The application of the ballbar instrument For the machine tool manufacturer, the ballbar instrument can be used to quickly check the machine tool and use it as a random machine tool accuracy acceptance document. At present, the ballbar instrument has been adopted by the international machine tool inspection standard, and the club is used at the same time. The instrument can easily compare the performance between machine tools, prompt machine problems, and establish machine performance files.
