What are the safe and correct operating procedures for milling workers?

Operators must be familiar with the operating points and technical performance of milling machines. Before starting the machine, he must carefully check all parts of the equipment, each handle and each speed change gear to ensure that it is in a reasonable position. If a fault is found, it should be repaired in time. It is forbidden to work with illness. Before starting the machine, the equipment must be oiled and lubricated according to the requirements of the lubrication chart. Operators should wear three tight work clothes, goggles (masks if necessary), masks when milling cast iron workpieces, and gloves are not allowed to operate the milling machine. Before the workpiece is clamped, the clamping method should be drawn up. When clamping the blank, the workbench should be well padded to avoid damaging the workbench. Check whether the fastening screws should be opened when the workbench moves and tightened when the workbench does not move. When assembling and disassembling the milling cutter, you should use a cloth pad, and you can't directly hold the milling cutter with your hands. When assembling and disassembling the milling cutter, the cone and cone hole of the milling cutter should be kept clean and clamped firmly. Before installing the milling cutter, check whether the cutter is in good condition, try to install the milling cutter near the spindle, and try it out after installation. The installation workpiece should be firm. When using a wrench, the milling cutter should avoid the direction of stress, so as to avoid the wrench slipping and causing work-related injuries. At work, feed by hand first, and then feed automatically step by step. When running the automatic feed, turn on the handwheel, and pay attention to whether the limit is firm. Don't put it in your head, and don't go to two extremes to damage the screw. When using the quick stroke, check whether it will collide in advance to avoid damaging parts and flying out of the milling cutter to hurt people. Always check whether the safety spring in the handle is effective and reliable. When cutting, it is forbidden to touch the blade and machining parts by hand. The measurement and inspection of the workpiece must be stopped, and it is not allowed to adjust the workpiece when cutting. Before the spindle stops, the feed must be stopped. If the cutting depth is large, the cutter should be stopped first, and the power supply should be cut off when changing gears. The clearance of changing gears should be appropriate, and the back of changing gears should be fastened to avoid falling off. When machining the blank, the rotation speed should not be too fast, and the tool quantity and feed speed should be selected well. If the machine tool is found to be faulty, it should be stopped immediately for inspection and reported to the maintenance department for repair. To remove debris, use a brush, not your hands or mouth. If a chip flies into your eyes, don't rub it with your hands. Seek medical treatment in time. Before coming off work, the operator should carefully clean and maintain the equipment as required, do a good job of lubrication and oiling, keep the surrounding site clean and sanitary, put away the product parts and turn off the power supply.
