Possible Causes and Solutions of the Accuracy Exceeding Tolerances in X62W Milling Machine
Milling machine is a common mechanical processing equipment, which has high automation and wide application range. The X62W milling machine is also a common type of milling machine. In practical application, it is often required to process workpieces and reach certain accuracy requirements. If the accuracy of the parts after machining exceeds the specified tolerance, it will bring great losses to the enterprise. Therefore, the causes of the accuracy exceeding the tolerance in X62W milling machine should be analyzed and solved correctly.
Cause 1: Improper Tool Selection
The selection of milling tools has a great influence on the accuracy of the machined parts, and the selection of the wrong tools will lead to the accuracy of the machined parts exceeding the tolerance. X62W milling machine should be equipped with high-quality carbide cutting tools and sharp inserts for stable cutting performance. Otherwise, the edges of the parts will cause burrs and reduce the accuracy of the parts.
Solution
The selection of the tools should be based on the size of the workpiece, the amount of vibration of the workpiece and the material of the workpiece. Do not use old and blunt tools for processing, and replace the tools regularly to ensure the cutting performance and accuracy of the parts.
Cause 2: Unstable Machine
The precision of X62W milling machine is greatly affected by the machine’s own damping performance and machine rigidity, which will cause the accuracy of the machined parts to exceed the tolerance. High-precision machining requires not only a stable machine body but also a strong cutting force to ensure the accuracy of the machined parts.
Solution
No matter when processing or setup and maintenance of the machine, it is necessary to keep the machine away from external shocks, such as sources of large vibration. In addition, the rotary table of X62W milling machine should be tightened to ensure the stability of the machine body, and regular maintenance should be carried out to ensure its high efficiency.
Cause 3: Poor Workpiece Fixture
The precision of the machined parts is also related to the quality of the fixture, and the improper use of the fixture will easily cause the accuracy of the parts exceeding the tolerance. X62W milling machine should use a high-precision workpiece fixture to ensure the true location of the workpiece, and it is necessary to regularly check the tightness of the workpiece fixture.
Solution
In the case of complex workpieces, it is necessary to use workpiece fixing fixtures with mechatronics to ensure that the workpiece is firmly fixed on the X62W milling machine. For serial parts with similar size, a universal workpiece fixture can be used to fix multiple workpieces at the same time to ensure repeatability and improve machining efficiency.
Conclusion
The accuracy of the machined parts on X62W milling machine cannot exceed the tolerance by any means. Therefore, it is necessary to analyze the possible causes of the accuracy exceeding the tolerance and to take effective measures to ensure the accuracy of the machined parts. The selection of tools, the stability of the machine body and the effects of the workpiece fixture must be strictly checked and managed to ensure the high accuracy of the machined parts.
