Ultra precision grinding machines are high-precision machining machines that are widely used in fields such as electronics, aviation, and automobiles. Its processing accuracy can reach the nanometer or even sub nanometer level, making it an important component of modern manufacturing industry. In this article, we will explore the basic principles, application fields, and development trends of ultra precision grinding machines.
1、 Basic Principles
Ultra precision grinding machines use high-speed rotating grinding wheels as cutting tools. During the grinding process, due to the relative motion between the high-speed rotation of the grinding wheel and the linear speed of the workpiece, the friction force between the grinding wheel and the workpiece increases instantly, which allows the particles of the grinding wheel to directly enter the workpiece, thus achieving the machining process. Therefore, the quality of the grinding wheel and the setting of processing parameters directly affect the accuracy of the workpiece after processing.
During the operation of ultra precision grinding machines, it is necessary to control parameters such as the rotational speed, feed speed, and cutting depth of the grinding wheel, which have a significant impact on the machining results. Meanwhile, due to the limited service life of the grinding wheel, it is necessary to regularly replace the grinding wheel and select an appropriate grinding wheel based on the different characteristics of the workpiece.
