Do you know the principles for confirming the grinding allowance of CNC cylindrical grinders

2025-04-11

Do you know the principles for confirming the grinding allowance of CNC cylindrical grinders?Reasonably confirming the grinding allowance of CNC cylindrical grinders is of great significance for increasing labor productivity and ensuring machining quality. Generally speaking, grinding is a precision machining process, and compared with other cutting methods, its cutting efficiency is much lower. If the margin is too large, it will reduce productivity and increase the power consumption of the grinding wheel and machine tool.In some cases, it can also reduce the quality of the parts, such as workpieces that have undergone surface nitriding and high-frequency heat treatment. The surface layer hardness is high, and the hardness decreases as it goes inward. If the margin before precision grinding is too large, the hardness of the surface layer after grinding will not meet the requirements. Of course, the margin ...

Detailed operating procedures for CNC grinding machines

2025-04-11

The operating procedures for CNC grinding machines can be divided into three parts: before work, during work, and after work.1、 Before work:1. The operator should wear work clothes and take protective measures.2. Check the device, power supply, etc. to ensure that the oil level, quality, and compressed air pressure in the fuel tank are normal or within the specified range.3. Are there any tools protecting the moving parts inside the machine tool protective cover? If so, they should be cleaned and placed in the corresponding position. The machine tool protective cover should be closed before operation.4. After two weeks of machine shutdown, the machine should be powered on to prevent data loss.5. Before the machine tool officially starts working, it should be run at low speed for 15 to 20 minutes to check if the lubrication is normal and if there is thermal balance.2、 At work:1. The operator mu...
