How to adjust the external cylindrical grinder on the grinding wheel?
1. Take minor adjustments.
The amount of adjustment is based on the criterion of restoring the geometric shape of the grinding wheel and producing a good grinding edge after several adjustments. When using a single point dressing tool, the diameter direction of the grinding wheel should be in contact with the axis at an inclination angle of 10-150 degrees. This will cause the single point trimming tool to produce a sharpening effect during regular rotation. The trimming tool with multi-point contact does not need to be tilted at this angle. Change to using the entire end face of the dressing tool in contact with the surface of the grinding wheel.
2. Keep cool.
Proper use of coolant can accelerate repair speed and improve repair efficiency. When the diamond dressing tool passes through the grinding wheel, install a coolant nozzle to cover the entire surface of the grinding wheel or continuously add coolant to the diamond dressing tool. After the dressing tool comes into contact with the grinding wheel to start dressing, it is never allowed to remove the dressing tool from the coolant. Otherwise, the diamond dressing tool may crack or rupture under the temperature changes of cold and hot.
Use a filter to accurately filter the coolant to prevent multiple cycles of dirt or chips in the coolant. Contaminated coolant can cause the grinding wheel to wear out quickly, increasing the number of times the grinding wheel needs to be repaired. Dry dressing should only be applied to the grinding wheel during dry grinding. Before starting work every day, turn off the coolant and let the sanding wheel idle for a few minutes. This can prevent the grinding wheel from breaking.
3. Vibration is the enemy of repair.
In grinding wheel dressing, it is important to effectively reduce vibration to avoid leaving dressing marks, collisions, and damage to dressing tools on the surface of the grinding wheel. This means that the balance of the grinding wheel must also be maintained, which is determined by the structural characteristics of the grinding wheel itself. Uneven density and the overall geometric shape of the grinding wheel can affect the inherent balance of a grinding wheel. Therefore, choosing a high-quality grinding wheel is also very important.
In order to further avoid vibration, it is necessary to ensure that the trimming tool is stably clamped on the clamp and maintains a small hanging amount to ensure that the trimming tool has corresponding rigidity.
