Tool Grinder Maintenance and Servicing

In the daily use of tool grinders, paying attention to maintenance can extend the service life of the grinder. Tool grinders come in many different models with various performance characteristics and features; we need to be mindful of this when operating them. At the same time, it’s especially important to pay close attention to routine maintenance and upkeep.

Tool grinding machines come in many different models, each with its own unique performance and features; therefore, we need to be mindful of these differences during operation. At the same time, it’s crucial to pay close attention to routine maintenance and upkeep. This article introduces how mechanical processing plants can perform scientific maintenance on tool grinding machines.

　　

　　For daily maintenance of the tool grinder, clean the entire machine after grinding each day. Do not use direct air blasts for cleaning, as this could allow metal chips to enter the guideways and compromise the grinder’s precision. When operating the equipment, avoid using a blower to direct airflow onto the worktable, in order to prevent dust and metal chips from rolling into the guideways and affecting their precision and smoothness.

　　The guide oil for the tool grinder should be replaced and refilled promptly—typically every 3 to 6 months, with the first replacement occurring in the third month and subsequent replacements every six months. Please use specialized lubricating oil for the grinder’s guideways. Regularly check whether the grinder’s steel cables are loose or properly secured to prevent breakage or compromise the accuracy of the feel. Periodically clean the surface guideways to prevent metal chips from wearing down the guideway surfaces and thus affecting their precision. You can use gasoline to thoroughly clean them. For debris embedded in the wear-resistant plates, gently remove it using a scraper. During operation, regularly inspect whether the machine body is stable and level.

　　Key component maintenance for precision CNC cylindrical grinding machines—grinding wheel spindle assembly: Check the spindle clearance, verify that the pulley bearings are not damaged, confirm that the grinding wheel motor is operating normally, and ensure that hydrostatic pressure has been established. Oil tank: Inspect the oil pump shaft for damage or fracture, and check for any defects such as oil-water mixing. Hydrostatic oil tank: Replace the oil every 6 months, clean the oil filter mesh, and verify that the oil-pressure relay contacts are in good condition. Worktable transmission mechanism: Check the accuracy of positioning, repeated positioning, and backlash. If any issues are found, disassemble and repair the ball screw, and inspect for oil-water mixing. Lateral feed mechanism: The inspection method is the same as that used for the worktable drive mechanism. Ball screw lubrication system: Check the lubrication effectiveness of the measuring components and verify that there is no blockage. If there is no oil flow, remove and repair the oil needle on the measuring component to ensure proper lubrication.

　　Use Tool grinder Before use, you must read the instruction manual to familiarize yourself with the machine’s structure, the functions of each handle, and the transmission and lubrication systems. Before operating the machine, add lubricant according to the lubrication instructions. Before using the machine, check whether all locking parts are securely fastened, whether the grinding wheel head lifting system, the worktable movement, and the electrical equipment are functioning properly. You should select an appropriate grinding wheel based on the material of the grinding tool and the requirements of the workpiece being processed, and promptly dress the working surface of the grinding wheel. If the tool grinder experiences a malfunction or unusual noise during operation, immediately disconnect the power supply and investigate the cause. During use, keep the guide rail surfaces clean. After finishing work, thoroughly remove any sand, metal chips, and dust from the machine. Unpainted surfaces should be coated with rust-preventive oil to prevent corrosion.

　　 Tool grinder Use and Maintenance of Linear Guides: Since linear guides are high-precision components, they should be used in a clean environment and appropriate protective measures should be taken to prevent dust and metal particles from entering, which could compromise the product’s accuracy and service life. At the same time, it is essential to perform regular rust prevention and lubrication maintenance on linear guides. Periodically clean them with kerosene and add fresh lubricant to avoid rusting and oil deficiency on the guide surface, which could lead to damage. Avoid disassembling linear guide components without authorization, as this could cause the steel balls inside the guide slider to fall out, thereby affecting normal operation. Machine tools should undergo regular maintenance, and any malfunctions should be promptly repaired to ensure that the machine tool remains in good working condition.
