Selection & Installation of Grinding Wheel for Cylindrical Grinding Machine
Here are some tips for how to select grinding wheel of cylindrical grinding machine:
1. When you grinding metal composite materials with poor heat transfer, grind thick-wall parts, or grind with slow-moving, then lower strength grinding wheel should be selected.
2. For same material workpiece, the harder grindign wheel should be selected for grinding the inner hole than the grinding surface, internal thread, etc.
3. For high speed, precision machining, interrupted surface grinding, workpiece grinding and polishing, hard grinding wheel should be selected.
Next, how to install new grinding wheel of cylindrical grinder?
1. The new grinding wheel should be carefully checked to see if there are cracks or scars, otherwise it is forbidden to use.
2. The new grinding wheel needs to undergo 2 times of careful static balance, that is, one time balancing before installation. And when install the spindle and adjust it with a diamond grinding disc, need to remove it and balance it once again.
3. When the new grinding wheel is installed, 0.5~2mm pad paper should be lined between the grinding wheel and the flange. The flange screws should be tightened evenly and symmetrically, but do not need to be tightened too much to prevent the grinding wheel from being crushed.
4. After the new grinding wheel is installed, carry out aeronautical rotation for no less than five minutes at the working speed ratio, and make sure that the installation is proper and everything is running normally before it can work.
5. It is necessary to check whether the grinding wheel cover is intact and reliable, and the CNC cylindrical grinding machine without grinding wheel cover is prohibited from starting.
