Warm reminder, when using diamond tools, please pay attention to the following:
1. The newly installed tools must be tested to see if they are beating. If they are beating, they cannot be directly operated. They must be adjusted to not be bounced before they can be used. Otherwise, the tools will wear out quickly and the carvings will not be smooth. Adjustment method: Use a small wrench to change the chuck to gently tap the high-speed rotating tool handle until the tool is stable. It is strictly forbidden to knock on the electronic machine. The adjustment method is to loosen the chuck, turn the tool at an angle or extend and retract a little.
2. Be sure to put water to cool (a drip device similar to a drip device in a hospital), such as a dry drill, the diamond on the tool head will be graphitized due to overheating, which will quickly wear out.
3. When drilling, try to avoid shaking, because shaking will cause partial damage to the tool and accelerate the damage of the entire tool.
4. Light pressure feed, diamond tools rely on grinding to process the work piece, excessive force, the grinding powder is not easy to remove, and tools (especially small tools) are also easy to damage.
