Q&A on the outer ring grinder.
1、 Q: What is the precision and roughness of cylindrical grinding machine processing?
Answer: As long as the precision of the measuring tool is high, the machining accuracy of the cylindrical grinder can reach 0.001mm, and the roughness can reach Ra0.40020.
2、 Q: What is the size of the bearing system between the outer cylindrical grinder and the bearing?
Answer: Bearing shells belong to sliding bearings. The spindle speed of the ordinary cylindrical grinder grinding wheel is very high, and the radial force caused by the grinding force is also very large. The rolling bearings are no longer "capable". Installing gaps that are too large or too small can affect the establishment of sliding.
3、 Q: What is the reason for the large vibration generated by a faster feed of the cylindrical grinder?
Answer: The vibration comes from the motion part: 1. Check if there is a soft connection between the grinding wheel spindle motor and the spindle housing.
2. Check if the dynamic balance of the grinding wheel is qualified.
3. Check whether the circular runout, radial clearance, and axial displacement of the grinding wheel spindle, headboard spindle, and tailstock are worse, to ensure the integrity of the spindle itself.
