What guarantees the machining accuracy of machine tools?
The machining accuracy of CNC machine tools depends on the accuracy of the machine itself. The accuracy of CNC machine tools includes geometric accuracy, positioning accuracy, repeated positioning accuracy and cutting accuracy.Geometric accuracy: also known as static accuracy, is a comprehensive reflection of the key components of CNC machine tool after the assembly of the comprehensive geometric error.
Positioning accuracy: it indicates the accuracy of the movement parts of the measured machine tool under the control of the numerical control device. According to the measured positioning accuracy value, the best machining accuracy of workpiece can be determined in the process of automatic machining. It refers to the gap between the actual position of parts or tools and the standard position (theoretical position, ideal position). The smaller the gap, the higher the accuracy. It is the premise to ensure the machining accuracy of parts.
