When using a Huniversal cylindrical grinding machine for high-precision grinding, before processing, the Huniversal cylindrical grinding machine must be fully inspected, including whether the various parameters and functions of the machine tool are normal, and whether the grinding wheel, oil pump, cooling pump and other components are in good condition. At the same time, ensure that the geometric accuracy of the machine tool (such as spindle rotation accuracy, linear motion accuracy, etc.) meets the requirements of high-precision grinding. Select the appropriate grinding wheel according to the material, shape and processing requirements of the workpiece. Workpieces of different materials require different types of grinding wheels to ensure the grinding effect and processing accuracy. At the same time, check whether the grinding wheel has defects such as cracks and wear, and ensure that its dimensional accuracy meets the requirements. Check and adjust the lubrication system to ensure that the worktable, grinding wheel frame and other components are well lubricated to reduce friction and wear. At the same time, check whether the cooling system is operating normally so that the workpiece and grinding wheel can be effectively cooled during the grinding process to prevent thermal deformation and burns.
Reasonably select grinding parameters, including grinding wheel speed, feed speed, grinding depth, etc. These parameters directly affect the machining accuracy and efficiency, and need to be accurately set according to the workpiece material and machining requirements. In high-precision grinding, the accuracy of micro-feed is crucial. By adjusting the transmission accuracy of the lateral feed mechanism, ensure that the grinding wheel can accurately and smoothly contact the workpiece surface to avoid overcutting or undercutting. In the low-roughness grinding process, the worktable is required to have no creeping phenomenon when moving at a low speed. Therefore, it is necessary to regularly check and adjust the motion stability of the worktable to ensure the smooth progress of the grinding process. The stability of the hydraulic system has a great influence on the grinding accuracy. It is necessary to check the pulsation of the hydraulic pump, the smoothness of the worktable reversing, and the vibration of each component of the hydraulic system to ensure that the hydraulic system operates stably and reliably.
The operator needs to have a high level of technical skills and rich operating experience, and be able to master the operating procedures and processing skills of the Huniversal cylindrical grinding machine. During the operation, the operator must strictly abide by the safety operating procedures and wear protective equipment to prevent accidents. During the processing, the operator needs to pay close attention to the processing status, adjust the grinding parameters and the grinding wheel status in time, and ensure the stability and consistency of the processing quality.
Regularly inspect and maintain the Huniversal cylindrical grinding machine, including cleaning the machine, replacing worn parts, adjusting the transmission mechanism, etc. This helps to maintain the good condition and processing accuracy of the machine. The grinding tool will wear during the processing process and needs to be inspected and replaced regularly. Timely replacement of worn grinding wheels can ensure the stability and consistency of processing quality. After the processing is completed, the processing quality needs to be inspected and evaluated, and the parameters and data during the processing process need to be recorded. This helps to analyze problems in the processing process and take timely measures to improve them.
When using a Huniversal cylindrical grinding machine for high-precision grinding, it is necessary to start from multiple aspects such as equipment inspection and preparation, processing process control, operator requirements, and maintenance and care to ensure the stability and consistency of processing quality.
