hammer's vibration to make bushhammered face rough.On the contrary, both reducing spring distance to increase spring elasticity and increase machine's press can be reduce bush hammer's vibration to make bushhammed face fine.

• Use and Maintenance for bush hammer

1. RPM of Manual grinding machine: RPM 700-800
2. Use as mush water as possible to cool the grinding machine

Such repeated several times, the more polishing,the better result will get. Some buffing pads due to the different components, allowing a sprinkler, and have been thrown over.
