In general, the rotating motion of the grinding wheel of a grinder does not require speed regulation. It can be driven by a three-phase asynchronous motor, and only one-way rotation is required. When the capacity is large, it can be started by Y-triangular depressurization. In order to ensure its processing accuracy, make it run smoothly, and ensure that the inertia of the worktable is small and no impact when the reciprocating movement of the worktable is reversed, hydraulic transmission is adopted to realize the reciprocating movement of the worktable and the grinding wheel. The box feeds horizontally.
The speed of the grinding wheel of the grinding machine is very high, and the grinding wheel is relatively hard and brittle, and cannot withstand heavy impacts during use. In this way, accidental improper operation will directly cause very serious consequences if the grinding wheel is crushed. The safety and technical work of processing is particularly important. Reliable safety protection devices must be adopted, and the operation must be concentrated to ensure that nothing is lost.
When the grinding wheel of a grinder is grinding, the fine sand and metal chips splashed on the workpiece will harm the eyes of the workers to a certain extent. If the workers inhale a large amount of this kind of dust, it is harmful to the body, and appropriate protection should be taken. Measures. The following safety technical issues should be paid attention to when grinding.
The grinder should pay attention to the clamping and clamping when loading the workpiece. The loosening of the workpiece during the grinding process will cause the workpiece to fly out and injure people or crush the grinding wheel. When starting to work, use manual adjustment to make the grinding wheel slower and approach the workpiece, and the starting feed should be small, and excessive force is not allowed to prevent collision with the grinding wheel.
The grinder needs to conduct a thorough inspection of the machine tool before starting up. This effectively includes the inspection of electrical equipment, operating mechanism and magnetic suction cups. After the inspection, it needs to be lubricated. After the lubrication, it is tested. Confirm that everything is good before use.
