CNC Machine Tool Processing Precision Abnormal Fault
Computer Numerical Control (CNC) machine tools, as a sophisticated kind of equipment, are being used more and more widely in various industries. While this helps to improve productivity, it also increases the risk of CNC machine tool processing precision abnormal faults which can lead to a decrease in product quality. Therefore, it is important for CNC machine tool operators and manufacturers to understand the typical abnormal faults of CNC machine tool processing precision, so as to take reasonable measures to prevent and reduce product quality losses.
To begin with, users must identify the common abnormal faults of CNC machine tool processing precision. These faults can be divided into three categories: backlash, operational gap, and geometric modification. The Backlash refers to the gap between the ball screw, end support and the reciprocating guide rail, which creates a loss in accuracy while the tool moves in a helical path. Operational gap is the insufficient openness of the gap between the two components, which will lead to unreasonable lower pressure and amplitude when machining, resulting in poor product accuracy. Lastly, geometric modification refers to the deviations which occur during machining when the machine tool is working, and result in inaccuracies in the product.
To prevent the occurrence of the above mentioned three types of abnormal faults, operators and manufacturers should detect the basic parameters of the CNC machine tool regularly. Specifically, runs tests on the main components such as the ball screw, end support, and reciprocating guide rail, as well as consistent checks on the positioning accuracy of all parts of the machine. Furthermore, if any defects are found, the operator or manufacturer should aim to adjust the relevant parts immediately to avoid any affecting on the processing precision of CNC machine tool.
In addition, the accumulation of dust and debris on the surface of the CNC machine tool, either inside or outside the machine, can interfere with the accuracy of the CNC machine tool processing precision. To prevent this, operators and manufacturers should carry out daily cleaning and maintenance in order to ensure that the environment is clean and free from dust, as well as to clear away any accumulated debris. This can be done simply using a vacuum cleaner, which can essentially reduce the damage to the processing precision of CNC machine tool.
To sum up, CNC machine tool processing precision abnormal faults can cause a decrease in product quality, which will lead to losses for both the operator and the manufacturer. Therefore, operators and manufacturers should understand the common abnormal faults of CNC machine tool processing precision, and take reasonable measures to detect the basic parameters, clean the environment, and adjust any components to ensure a precise output. In doing so, the operator or manufacturer can significantly reduce the likelihood of product quality losses.
