Uneven Finishes
Causes of Uneven Finishes
You may notice that some gears have surfaces that look or feel different after grinding. Uneven finishes often happen when the grinding tool does not touch the gear in the same way across the whole surface. If the number of contact points changes during grinding, the cutting forces will not spread out evenly. This can cause the gear profile to shift or form errors. The way the tool touches the gear, called the flank sequence, also matters. When the contact switches between even and uneven numbers, you get more profile deviations. The pressure angle of the tool affects how the grinding force spreads. If you do not control these factors, you will see inconsistent finishes on your gears.
Troubleshooting Tips
You can fix uneven finishes by checking a few key things. First, look at the grinding wheel and see if it has worn down in some spots. Dress the wheel to make sure it has the right shape. Check the setup of your gear and grinding tool. Make sure the gear sits straight and does not move during grinding. Watch the grinding process and listen for changes in sound or vibration.
