Debugging of CNC machine tool

How to adjust the CNC machine tool? Before debugging, the horizontal position of the machine bed should be adjusted first, the main geometric accuracy of the machine tool should be roughly adjusted, and then the relative position between the main moving parts and the host machine should be adjusted, such as the correction of the position of the manipulator, tool magazine and host machine tool change. After that, add lubricating oil, hydraulic oil and cutting fluid according to the requirements of the machine manual, and connect the external air source.

More than 80% of the machine tools must be debugged in the field before they can meet the technical specifications. The correctness of this step largely determines whether the CNC machine tool can play a normal economic efficiency and its own service life. Therefore, when the new machine tool is checked and accepted, the machine tool can be ensured to achieve its technical indicators and expected quality and efficiency at the beginning of installation. The new machine tool needs to be tested again after half a year’s use, and then it can be verified once a year. The machine tool error is detected regularly and the pitch and reverse clearance are corrected in time.

The NC machine tool should be started and debugged according to the following steps:

1、 Preparation before commissioning

Before debugging the machine tool, the horizontal position of the machine bed should be adjusted first, the main geometric accuracy of the machine tool should be roughly adjusted, and then the relative position between the main moving parts and the host machine should be adjusted, such as the correction of the position of the manipulator, tool magazine and the host machine tool change. After that, add lubricating oil, hydraulic oil and cutting fluid according to the requirements of the machine manual, and connect the external air source.

2、 Power on test run of machine tool

The power on test run of machine tool generally adopts the power on test of each component separately, and then makes a comprehensive power supply test. According to the machine tool manual, check whether the main parts of the machine tool function normally and completely, so that all parts of the machine tool can operate and move.

3、 Adjustment of machine tool accuracy and function

1. Using the precision level instrument and other testing tools, the level of the main bed of the machine tool is adjusted by adjusting the iron pad, so that the geometric accuracy of the machine tool can reach the allowable tolerance range;
2. For the automatic tool change device, adjust the position of the tool magazine, manipulator, travel parameters, etc., and then check the action with the command, which is required to be accurate;
3. For the machine tool with APC automatic exchange table, after adjusting the relative position, carry out automatic load exchange;
4. After the adjustment of the machine tool, carefully check whether the parameter setting values in the numerical control system and the programmable controller conform to the data specified in the random index, and then test the main operation functions, safety measures, execution of common instructions, etc.
5. Check the auxiliary functions and accessories of the machine tool.
