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...

What are the three major factors causing vibration in grinding machines

2025-04-10

There are various reasons for the vibration of grinding machines, and the following are the three main reasons compiled by the editor:1. First, check the horizon. If the level of the foundation screws of the machine tool is not adjusted properly, it will cause resonance of the machine tool. Because sometimes the flatness of the ground in the processing site is not good, it is necessary to adjust the horizontal screws to make the machine reach an uneven height. We need to check whether each screw of the foot is properly installed in the floor mat. Use a spirit level to check if the front, back, left, and right are level, and tighten the screws. 2. If the above actions have been taken but the vibration is still not resolved, we should check whether it is due to the virtual space of the ground floor. If the ground is terrazzo or paved with floor blocks, it is relatively solid. If it is a cement floor, the grou...

Discuss the methods to solve the problem of warping during the grinding process of CNC cylindrical grinders

2025-04-10

Discuss the methods to solve the problem of warping during the grinding process of CNC cylindrical grinders.CNC cylindrical grinding machines are widely used in machining applications, but warping may occur during the grinding process. To solve this problem, the following methods can be used:1. When grinding the above-mentioned thin sheet workpieces on a CNC cylindrical grinder, an elastic clamping arrangement is selected to complete the positioning and clamping of the thin sheet workpieces in a free state. Place a layer of 0.5mm thick rubber between the workpiece and the magnetic worktable. When the workpiece is subjected to magnetic attraction, the rubber is compressed, the elastic deformation is reduced, and then a flat surface of the workpiece can be ground. Repeatedly grinding several times can achieve the required machining accuracy.2. Use epoxy resin bonding agent to bond the thin sheet workpiece to ...

Data display and zero offset of CNC end face cylindrical grinder.1、 The data of the CNC end face cylindrical grinder shows:If the "handwheel mode" is selected under the "JOG" mode, the system will require confirmation of the X-axis or Z-axis. If not confirmed, the tool holder will still move in the previous direction, which can easily cause the tool holder to move incorrectly and result in cutting situations.2、 Zero offset of CNC end face cylindrical grinder:During the operation of modern CNC systems, people often use a zero offset command from G54~G59 tape machines to set the position of the workpiece zero point in the machine coordinate system for CNC end face cylindrical grinders. When using this method, attention should be paid to whether tool compensation is used and which point is used as the reference point for setting the tool compensation value. If the displacement of the machine tool...

Grinding methods on cylindrical grinders

2025-04-10

Grinding methods on cylindrical grinders.1. Longitudinal grinding method: When grinding the outer circle using the longitudinal grinding method, the high-speed rotation of the grinding wheel is the main motion, and the workpiece undergoes circular feed motion while also undergoing longitudinal reciprocating motion with the worktable, achieving axial feed along the workpiece. The longitudinal grinding method is suitable for grinding larger workpieces and is a commonly used method for single piece and small batch production.2. Horizontal grinding method: When using the horizontal grinding method to grind the outer circle, the width of the grinding wheel is larger than the grinding width of the workpiece, and the workpiece does not need to make longitudinal feed motion. The grinding wheel continuously or intermittently makes transverse feed motion at a slow speed to achieve radial feed of the workpiece until t...
