Anong mga salik ang nakakaapekto sa katumpakan ng machining ng CNC Machine Tool Co., Ltd. ng CNC rolling at bending machine ng Manhart (Guangdong)?

The machining accuracy of CNC rolling and bending machines is influenced by various factors, which may come from multiple aspects such as the equipment itself, the machining process, environmental factors, and operating methods. The following are some main influencing factors:
1. * * Machine tool error * *: including manufacturing error, installation error, and wear of the machine tool. These errors can be attributed to the guide rail guidance, spindle rotation, and transmission chain of the machine tool. The accuracy and stability of machine tools directly affect the machining accuracy of rolling and bending machines.
2. * * Adjustment error * *: Error caused by inaccurate machine tool adjustment. This may be due to the operator’s imprecision or negligence in adjusting machine parameters.
3. Residual stress inside the workpiece: Residual stress may occur inside the workpiece during rough manufacturing, heat treatment, cold straightening, and cutting processes. These stresses may be released during the machining process, causing deformation of the workpiece and thus affecting machining accuracy.
4. Environmental impact on the processing site: There may be various interference factors on the processing site, such as small metal shavings, electromagnetic wave interference, voltage fluctuations, and dust. These factors may all have an impact on the machining accuracy of CNC rolling and bending machines.
5. * * Manufacturing errors and wear of fixtures * *: The errors of fixtures may include positioning elements, tool guide elements, indexing mechanisms, and specific manufacturing errors of clamps. During the use of fixtures, wear and tear can also cause errors, which directly affect the positioning and machining accuracy of the workpiece.
6. * * Thermal error * *: The heat generated during the machining process may cause temperature changes and thermal expansion of various components of the machine tool, resulting in thermal errors. This error may cause a change in the relative position between the tool and the workpiece, affecting machining accuracy.
7. * * Workbench motion accuracy error * *: During the rotation of the workbench around the three coordinate axes in space, there may be errors in roll angle, pitch angle, and yaw angle. These errors will affect the positioning and machining accuracy of the workpiece.
8. * * Perpendicularity error between component movements * *: The movement of machine tool components in the vertical, longitudinal, and transverse directions may have verticality errors, which can affect the accuracy and consistency of workpiece processing.
In summary, the machining accuracy of CNC rolling and bending machines is influenced by various factors such as the accuracy of the machine tool itself, various factors during the machining process, and environmental factors. To ensure machining accuracy, it is necessary to comprehensively consider these factors and take appropriate measures for control and optimization.
