grinder for common sense of safety protection of introduction

Grinder is a kind of machine tool which uses abrasive tools to grind the surface of workpiece. Grinding machine has a wide range of applications, not only can carry out high-precision, high-power grinding, but also can carry out grinding with small surface roughness, and suitable for processing a variety of hard and brittle data, so it is widely expected in industrial application. Here are some common sense of grinder safety protection to introduce to us, hoping to provide some ideas for brothers who need assistance.

Grinding is widely used, and it is one of the most important methods for fine machining of machine parts. However, due to the high speed of the grinding wheel, the grinding wheel is hard, brittle and can not withstand heavy impact. Occasionally, improper operation will cause severe results when the grinding wheel is smashed. Therefore, it is very important to grasp the safe operation of grinding equipment. In addition, the fine sand and metal chips splashed on the workpiece of grinding wheel during grinding will damage workers' eyes. If workers inhale a large amount of dust, it will be harmful to their health, and appropriate protection measures should also be adopted. Some safety technical problems should be paid attention to during grinding. Before driving, the machine tool should be carefully checked, including the operation organization, electrical equipment, magnetic chuck and other fixtures. After checking, it can be smoothed. After smoothing, it can be tested. It can only be used after all outstanding achievements are recognized. When the workpiece is clamped, attention should be paid to the correct and tight clamping. In the grinding process, the workpiece looseness will cause serious results such as flying out of the workpiece, hurting people or crashing the grinding wheel. At the beginning of the operation, the manual adjustment method should be used to make the grinding wheel slow and close to the workpiece. The initial feed rate should be small, and excessive force is not allowed to avoid bumping the grinding wheel. When it is required to operate the reciprocating motion of the worktable with the iron stopper, it should be adjusted accurately according to the grinding length of the workpiece, and the iron stopper should be firmly fixed. When replacing the grinding wheel, it is necessary to check the appearance first to see if there is any trauma, and then knock it with a wooden hammer or mallet. The sound is loud and there is no crack. When installing the grinding wheel, it is necessary to install it according to the rules and requirements. After the static balance debugging, the device can be used after the test run is normal. Workers should wear protective glasses during operation, and trim the grinding wheel in a balanced way to avoid collision. Measuring workpiece, adjusting or scrubbing machine tool should be carried out after shutdown. When using the magnetic chuck, the disk surface and the workpiece should be cleaned, close and firmly absorbed. If necessary, the iron block can be added to avoid the displacement or flying out of the workpiece. Pay attention to install the wheel guard or the machine baffle, and stand on the front side of the high-speed rotating wheel. There are many kinds of products processed by the machining profession. The size of the workpiece is different, and the processing accuracy is different. The relative demand of grinding wheel speed is different from the main axis speed, so it is difficult to adjust the spindle speed to the desired condition. Because of the awesome stress and tortuous process of the shaft, the grinding wheel will have different feed torque, which will cause the wheel speed and torque to change differently. The chatter pattern / burn pattern will also happen. The grinding accuracy is difficult to ensure, resulting in low power output and low quality.
