In the stone processing industry, stone calibration machines are the core equipment to ensure processing accuracy and surface quality, and their stability is crucial to production efficiency. However, in actual operation, stone calibration machines may face a variety of mechanical failures, which not only affect equipment performance, but may also have a significant impact on processing efficiency and finished product quality.
Types and causes of mechanical failures
Common mechanical failures of stone calibration machines mainly include screw misalignment, loose drive lines, bearing damage, and drive shaft wear. These problems usually stem from factors such as wear and tear caused by long-term operation of the equipment, external impacts caused by improper operation, and lack of regular maintenance. For example, misalignment of the lead screw may be due to structural fatigue under long-term load, while loosening of the drive line may be due to loose connections caused by vibration and thermal expansion and contraction.
Fault diagnosis and location
Effective troubleshooting is the first step in solving mechanical failures, which usually includes the following links:
Observation and monitoring: Operators need to carefully observe the operating status of the equipment and pay attention to whether there are signs of abnormal sounds or vibrations. These anomalies are often precursors to mechanical failures, and timely detection can avoid more serious problems.
Inspection and Measurement: Use professional tools to carefully inspect and measure each component of the equipment. For example, check the tightening of the screw, measure the wear degree of bearings and drive shafts, etc., to ensure that all components are in normal working condition.
Analyze the cause of the failure: Combine the observation and measurement results, and the operation history and operation records of the equipment to conduct a comprehensive analysis of the cause of the failure. This process helps determine the root cause of the failure so that effective solutions can be developed.
Troubleshooting strategy
Lead screw misalignment
Phenomenon: The machine head cannot be returned to zero, resulting in a decrease in processing accuracy.
Solution strategy: Under the premise of ensuring safety, turn off the power of the equipment and use professional tools to adjust the position of the screw to restore it to the correct state. During the adjustment process, it is necessary to ensure the tightness and lubrication of the screw to prevent misalignment from occurring again.
Loose drive wire
Phenomenon: Abnormal sound occurs when the device is running or the operation is unstable.
Solution: Check the connection of the drive cable to make sure it is secure and in good contact. If looseness is found, the drive cable needs to be re-fixed or replaced. At the same time, check the wear of the drive line and replace it in time if necessary to avoid the expansion of the fault.
Bearing damage
Phenomenon: Abnormal noise or increased vibration occurs when the equipment is running.
Solution strategy: When ensuring safety, turn off the power of the equipment, remove the damaged bearing and replace it with a new bearing. During the replacement process, it is necessary to ensure that the model and specifications of the new bearing match the original equipment, and the installation and adjustment must be carried out in strict accordance with the equipment instructions.
Drive shaft wear
Phenomenon: Stuttering or decreased accuracy occurs when the device is running.
Solution: Check the wear of the drive shaft. If the wear is serious, replace the drive shaft with a new one. During the replacement process, ensure that the size and accuracy of the new drive shaft match the original equipment, and install and adjust it in strict accordance with the equipment instructions. At the same time, lubricate and maintain the drive shaft regularly to extend its service life.
