A grinder is a commonly used mechanical equipment used to grind the surface of a workpiece to the required accuracy and finish. Its principle is to achieve grinding of the workpiece surface through the relative motion of grinding wheels or abrasives on the workpiece surface.
Specifically, the principle of a grinder includes the following aspects:
Selection of grinding wheels: Different types, specifications, and hardness of grinding wheels are selected based on factors such as workpiece material and grinding requirements.
Installation of grinding wheel: Install the grinding wheel on the spindle of the grinding machine and adjust the position, speed, feed speed and other parameters of the grinding wheel.
Clamping of workpieces: Clamp the workpieces to be processed on the workbench of the grinding machine, so that they come into contact with the grinding wheel.
The relative motion between the grinding wheel and the workpiece: By controlling the speed and feed rate of the grinding wheel, it generates relative motion with the surface of the workpiece for grinding processing.
Spray of coolant: To prevent overheating of the grinding wheel and workpiece, the grinding machine usually sprays coolant to maintain a certain temperature on the surface of the grinding wheel and workpiece.
Overall, the grinding machine grinds the surface of the workpiece through the rotation and feed motion of the grinding wheel to achieve the required accuracy and smoothness. The principles of different types of grinding machines vary, but they are generally based on the above aspects.
