What are the reasons for the crawling of CNC end face cylindrical grinding machines

2025-04-10

What are the reasons for the crawling of CNC end face cylindrical grinding machines?The crawling of CNC end face cylindrical grinding machines is often caused by poor lubrication of the worktable running guide rails. The lubrication is too small, or simply due to the blockage of the lubrication channel, the lubricating oil cannot reach the guide rail at all, which increases the friction between the guide rail pairs and causes the crawling phenomenon of the CNC end face cylindrical grinder. At this point, we only need to open up the lubrication channel or increase the lubrication amount appropriately to solve the problem of workbench crawling. It should be noted that the lubrication amount between the guide rail pairs cannot be adjusted too much, otherwise it will cause drift during the operation of the worktable, which will lead to related quality problems of the ground workpiece.Hydraulic system adjustment...

2025-04-10

Why does the stability of a grinder determine its quality?There are many hydraulic transmission reversing methods currently used in grinding machines. Based on the analysis of commonly used hydraulic transmission reversing methods, a simple analysis will be made below. The direction change method and control parameters in the system using a stroke direction change valve have a decisive effect on the direction change impact. Below, we will discuss the direction change impact problem of the grinder from the perspective of direction change method and control strategy.A pull rod is connected to the reversing valve core to use a stroke reversing valve for reversing. Use the travel stop on the workbench to push the pull rod to achieve automatic direction change. When the worktable moves slowly, when the directional valve reaches the middle position, whether the left and right chambers of the hydraulic cylinder ar...
