Safety Protection For Grinding Applications

Grinding machining is widely used and is one of the main methods for precision machining of machine parts. However, due to the high speed of the grinding wheel, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Occasional improper operation and crushing the grinding wheel can cause very serious consequences. Therefore, the safety technical work of grinding processing is particularly important. Reliable safety protection devices must be adopted, and the operation must be concentrated to ensure foolproof.

In addition, the fine sand and metal swarf splashed on the workpiece of the grinding wheel during grinding will hurt the eyes of the worker. If the worker inhales this dust in a large amount, it will be harmful to the body, and appropriate protective measures should also be taken. Pay attention to the following safety technical issues when grinding.

Before starting the machine, you should carefully carry out a comprehensive inspection of the machine tool, including the inspection of the operating mechanism, electrical equipment and magnetic chucks. After inspection, lubricate and test run after lubrication to confirm that everything is good before use.

When installing the workpiece, pay attention to the correct and tight clamping. During the grinding process, the workpiece will loosen and it will cause serious consequences such as flying out of the workpiece or hurting the grinding wheel. When starting work, apply the manual adjustment method to make the grinding wheel slower to approach the aluminum  parts. The starting feed should be small, and no excessive force is required to prevent collision with the grinding wheel. When it is necessary to control the reciprocating movement of the worktable with the iron stopper, it should be accurately adjusted according to the grinding length of the workpiece, and the iron stopper should be firmly tightened.

When replacing the grinding wheel, you must first conduct a visual inspection to see if there are any injuries, and then hit with a wooden hammer or wooden stick. The sound must be clear and crack-free. When installing the grinding wheel, it must be assembled according to the stipulated method and requirements. After the static balance is debugged, the installation is carried out and the commissioning is conducted. After everything is normal, it can be used.

Workers should wear protective glasses at work, and balance them when dressing the grinding wheel to prevent impact. Measuring the workpiece, adjusting or wiping the machine must be done after the machine is stopped. When using a magnetic chuck, the surface of the disk and the workpiece should be cleaned, pressed tightly, and sucked firmly. If necessary, iron can be added to prevent the workpiece from shifting or flying out. Pay attention to the installation of the grinding wheel shield or the CNC machine china tool baffle, and the position should be over the front of the high-speed rotating grinding wheel.
