An external cylindrical grinder is a machining equipment used for grinding cylindrical, conical, and spherical parts. The feed rate refers to the forward distance of the workpiece per unit time during the movement of the grinding head during grinding. Generally speaking, the higher the feed rate, the higher the machining efficiency. However, if the feed rate is too high, it may lead to a decrease in the quality of the grinding surface, as well as an increase in the risk of grinding head wear and equipment wear.
In order to ensure a balance between grinding efficiency and machining quality, it is necessary to control the feed rate reasonably based on specific machining requirements and equipment performance. In machine tool processing, the control of feed rate is usually achieved by adjusting parameters such as workpiece speed, grinding head speed, and feed shaft transmission mode.
There are several methods to adjust the feed rate of an external cylindrical grinder, including the following:
1. Adjusting the feed handwheel: Machine tools usually have two methods: manual wheel and automatic feed. The feed speed can be changed by adjusting the manual wheel. Hand cranked wheels usually have a ruler that can adjust the feed rate as needed.
2. Adjusting the speed of the feed motor: The feed motor of a machine tool usually has adjustable speed function, which can change the feed speed by adjusting the motor speed.
3. Adjusting the feed servo system: Machine tools usually use servo control systems, which can change the feed speed by adjusting servo parameters.
4. Adjusting the feed screw: The feed screw of a machine tool generally has multiple speeds to choose from, and the feed speed can be adjusted according to the processing needs.
It should be noted that when adjusting the feed rate of the external cylindrical grinder, it is important to avoid being too fast or too slow to avoid affecting the grinding quality and processing efficiency. At the same time, it is necessary to choose the appropriate feed rate according to different processing workpieces and materials.
