CNC surface grinding machine is an important equipment in modern machining, the stability of its running speed directly affects the machining accuracy and production efficiency. However, in the process of use, sometimes the speed of CNC surface grinding machine will be worse. This paper will carry on the reason analysis, and put forward the corresponding solution.

1. Reason analysis

1. Hydraulic system problem: The hydraulic system of CNC surface grinding machine is the core part of its power transmission. When the hydraulic system fails, such as hydraulic cylinder wear, hydraulic oil pollution or hydraulic pipeline blockage, it will cause the grinding machine speed to slow or unstable.

2. Transmission parts wear: the transmission parts of the CNC surface grinding machine, such as gears, bearings, lead screws, etc., will wear after a long time of use, resulting in reduced transmission efficiency, which affects the running speed of the grinding machine.

3. Control system failure: The control system of CNC surface grinding machine is the key to achieve high-precision machining. When the control system fails, such as controller damage, sensor failure or program errors, it will cause the grinder speed to be unstable or unable to reach the expected speed.

4. Poor lubrication: CNC surface grinding machine needs good lubrication to reduce friction and wear during operation. If the lubrication is poor, it will lead to increased friction inside the machine tool, which will slow down the grinding machine speed.

Second, the solution

1. Check and maintain the hydraulic system regularly to ensure the cleanliness of the hydraulic oil and the integrity of the hydraulic cylinder, and replace the damaged hydraulic components in time.

2. Check the wear of the transmission parts regularly, replace the parts with serious wear in time, and maintain the good condition of the transmission system.

3. Check and debug the control system regularly to ensure the normal operation of the controller and the accuracy of the sensor, and repair program errors in time.

4. Check the working state of the lubrication system regularly, replace the lubricating oil in time, and maintain the good lubrication state inside the machine tool.

In short, the reasons for the speed deterioration of CNC surface grinding machines are various, and we need to investigate and solve them from many aspects. Only by ensuring that all parts of the machine tool are in good working condition can we ensure the stable operation and efficient processing of the CNC surface grinding machine.
