In modern manufacturing, internal thread grinding centers are important equipment for precision machining, and their stable operation is crucial for product quality and production efficiency. However, due to prolonged high load operation and complex working environments, such machine tools are inevitably prone to various malfunctions. This article will provide a detailed introduction to several common faults, effective troubleshooting methods, and maintenance strategies to help users better manage and maintain their equipment, thereby extending its service life and improving overall performance.

1、 Main spindle system malfunction and handling

1. Abnormal vibration or increased noise

When strong vibrations of unknown cause are detected in the spindle, the first consideration should be whether it isInternal thread grinding centerUnbalanced rotation caused by bearing wear. At this time, it is necessary to immediately stop the machine for inspection and replace high-quality original parts if necessary to ensure the restoration of accuracy. In addition, it is also possible that poor lubrication has intensified the collision sound between internal parts due to dry friction; This problem can be solved by adding an appropriate amount of specialized lubricating oil.

2. Unstable speed or even stalling

There are various reasons for this phenomenon, which may be due to excessive fluctuations in the power supply voltage affecting the normal operation of the motor; It may also be due to improper parameter settings in the control system triggering the protection mechanism to automatically stop outputting power source signals to the drive actuator, resulting in delayed response actions beyond the expected target value range! For such situations, it is recommended to first investigate whether there are poor contacts or other issues with the external power supply lines, and then gradually delve into the electrical cabinet to find the specific root cause for repair and treatment, in order to restore normal operation~

2、 Common problem analysis of feed mechanism

1. Inaccurate positioning or crawling phenomenon occurs

This usually indicates that there is a large gap or insufficient preload between the guide rail pairs! The solution is to readjust the tightness of the inlay until the desired fit is achieved; At the same time, remember to regularly clean the dust and impurities accumulated on its surface to prevent further damage to already fragile and sensitive parts. In addition, it is important to maintain appropriate load balancing principles to avoid adverse consequences such as deformation and distortion caused by excessive unilateral force!

2. Slow movement speed accompanied by stuttering sensation

This symptom is often caused by an increase in resistance due to excessive preloading of the ball screw pair, which is just one of the manifestations of the result! Relaxing the locking nut appropriately can effectively alleviate the current predicament; But if it is due to foreign objects invading and obstructing the smooth passage path, then the protective cover must be removed and cleaned thoroughly to make it work. Of course, the potential defect factors that may exist in the servo drive unit itself cannot be ignored, and the issue of space size cannot be ruled out

3、 Key maintenance points for cooling system

Good heat dissipation conditions are one of the fundamental guarantee measures for ensuring long-term continuous operation of the entire machine, which cannot be ignored, my friends!! Once the water temperature is observed to rise beyond the normal threshold range, fresh coolant should be replaced in a timely manner to prevent boiling, overflow, waste of resources, and potential safety risks such as scalding of operators. At the same time, close attention should be paid to whether the filter is severely blocked, which hinders the smooth and unobstructed flow of liquid to complete the heat exchange process task. What is the effect of achieving the established goal smoothly? If the filter screen is found to be damaged, it is necessary to contact professionals as soon as possible to repair and replace it with a new component before it can continue to be used. Wow!!

In summary, after a detailed analysis of the typical fault cases that may occur in the main components of several internal thread grinding centers and providing corresponding solutions, I believe everyone has mastered an effective set of daily inspection procedures, right? As long as you strictly follow the technical manual guidance provided by the manufacturer to implement standardized operating procedures and persistently carry out preventive maintenance work, your beloved machine will undoubtedly maintain good work efficiency for a long time and create more value returns for your enterprise!
