The reasons and measures for excessive cutting force in CNC cylindrical grinding machines may include the following aspects:
1. Excessive tool wear: If the wear is excessive, it will cause the contact area between the tool and the workpiece to decrease, resulting in an increase in the cutting depth of each cutting surface and excessive cutting force. The solution is to replace the tool or grind it in a timely manner.
2. Improper grinding parameters: If the grinding parameters are set improperly, such as too low cutting speed, too fast feed rate, and too deep grinding, it will cause excessive cutting force during the grinding process of the CNC cylindrical grinder. The solution is to adjust the grinding parameters based on factors such as workpiece material and shape to achieve the best grinding effect.
3. The contact area between the tool and the workpiece is too small: If the contact area between the tool and the workpiece is too small, it will increase the cutting depth on the surface of the workpiece, resulting in excessive cutting force. The solution is to adjust the grinding process or replace the appropriate tool.
4. Improper tool installation: Improper tool installation, such as incorrect angle or insufficient clamping force, can cause excessive tool displacement, resulting in excessive cutting force. The solution is to install correctly and ensure sufficient clamping force.
5. Improper selection of abrasive: If the abrasive is selected improperly, such as particles that are too large or too hard, it will result in excessive cutting force during the grinding process. The solution is to choose the appropriate abrasive.
6. Machine tool problems: If there are problems with the CNC cylindrical grinder itself, such as insufficient precision of the grinder guide rail, loose transmission components, etc., it can lead to excessive cutting force during the grinding process. The solution is to check the problems with the machine tool itself and perform timely maintenance and upkeep.
