A surface grinder is a commonly used machine tool for mechanical processing. There are high requirements for motion stability, commutation accuracy, and commutation frequency. The motion inertia of large high-speed surface grinders is very large. When they change direction, it will cause a sharp increase in back pressure, resulting in a reversal impact, which will have a catastrophic impact on the machine tool. Therefore, the problem of smooth reversal has become an important factor restricting the improvement of grinding machine working speed and machining accuracy. There are many hydraulic transmission reversing methods currently applied to surface grinders. Based on the analysis of commonly used hydraulic transmission reversing methods, a simple comparison and analysis will be made below. The method of reversing using a stroke reversing valveA pull rod is connected to the reversing valve core to use a ...

The overall structural design of a CNC cylindrical grinder is directly related to its machining accuracy and stability. This type of precision machine tool typically uses high-strength bed bodies to ensure stability and durability during high-speed grinding processes. The bed is the foundation of a CNC cylindrical grinder, and its structural form and material selection have a significant impact on the overall performance of the machine. The bed body is usually made of high-strength cast iron or steel, and the internal ribs are arranged in a box shape, with high overall stiffness and good thermal deformation characteristics. This design can effectively reduce vibration and deformation during the grinding process, and improve machining accuracy. The grinding wheel frame and worktable feed system of the CNC cylindrical grinder are also important components of its overall structure. The grinding wheel ho...

In the field of precision manufacturing, the surface roughness of CNC cylindrical grinders is a key indicator for evaluating their machining quality. Surface roughness not only affects the appearance of parts, but also directly relates to their load-bearing capacity, wear resistance, and corrosion resistance. The CNC cylindrical grinder can achieve very small surface roughness values by using high-precision grinding wheels and accurately controlled feed rates. In addition, the introduction of numerical control technology makes the grinding process more stable, and through programming, the movement path and speed of the grinding wheel can be accurately controlled, thereby further reducing surface roughness. The operator can optimize the machining effect by adjusting grinding parameters such as the type of grinding wheel, grinding speed, and grinding depth. For example, using finer grinding wheels with...
