A brief analysis of the working accuracy of external grinding machines

Excessive temperature can affect the grinding effect of CNC cylindrical grinders. During grinding on a grinder, excessive grinding temperature can cause macroscopic thermal damage such as burns, cracks, or deteriorated layers on the surface of the workpiece, as well as microscopic thermal damage such as high-temperature tempering phase transformation and even secondary quenching phase transformation on the surface. These thermal damages can damage the surface integrity of the workpiece, reducing its surface characteristics such as wear resistance, corrosiveness, and strength. Secondly, excessively high temperatures may also affect the geometric and shape accuracy of the workpiece. Due to the increase in temperature, the difference in thermal expansion between the workpiece and the tool may lead to an increase in machining errors. In addition, excessive temperature may also cause deformation and wear of...

CNC cylindrical grinder is a high-precision grinding equipment, but some malfunctions may still occur during use. The common equipment failure analysis is as follows:1. The grinding wheel cannot rotate or has abnormal speed: it may be due to motor failure, loose or worn connecting parts of the grinding wheel, which causes the grinding wheel to not rotate normally. The solution includes checking the motor, connecting components, and replacing the grinding wheel.2. Excessive jumping or vibration of the grinding wheel: It may be due to unbalanced grinding wheel, unstable workpiece support during grinding, or uneven wear of the grinding wheel. The solution includes dynamically balancing the grinding wheel, adjusting the workpiece support, and replacing the grinding wheel.3. Unstable grinding accuracy: It may be due to improper settings of the CNC system, poor grinding wheel dressing, unreasonable workpiece clam...

An external cylindrical grinder is a machining equipment used for grinding cylindrical, conical, and spherical parts. The feed rate refers to the forward distance of the workpiece per unit time during the movement of the grinding head during grinding. Generally speaking, the higher the feed rate, the higher the machining efficiency. However, if the feed rate is too high, it may lead to a decrease in the quality of the grinding surface, as well as an increase in the risk of grinding head wear and equipment wear.In order to ensure a balance between grinding efficiency and machining quality, it is necessary to control the feed rate reasonably based on specific machining requirements and equipment performance. In machine tool processing, the control of feed rate is usually achieved by adjusting parameters such as workpiece speed, grinding head speed, and feed shaft transmission mode.There are several methods to...
