The cylindrical grinding machine and the lathe are 4m apart, and the surface of the ground workpiece is corrugated. In order to reduce the surface ripple; the wooden cover anti-vibration groove can be added around the cylindrical grinding machine, as follows: We install the 3μm digital display on the MQ1350A×3000 cylindrical grinding machine, which not only facilitates the operator to machine parts, but also improves the product quality. You can also monitor the interference from your surroundings. Because the grinding head is floating on the machine guide rail, the vibrating grinding bed and the grinding head move relative to each other. From the digital display, the relationship between the vibration source and the vibration can be seen. When the driving at a distance is started, the digital display is reflected as 3~8μm; when the driving is running at the top of the grinding machine, the digital display is reflected as 20 -25μm; when the nearby roughing machine C650 cuts intermittently, the digital display is reflected as 51
