During the engraving process, dust and debris from the engraving can easily accumulate on the rotary shaft. Therefore, it is necessary to wipe the rotary axis every two weeks during frequent engraving to ensure that there is no dust or impurities. This can effectively prevent slipping or uneven engraving during the engraving process.
In cases of frequent engraving, it's important to keep the chuck dry and clean to prevent rust. You can use cotton swabs or a cloth to wipe off any dust or impurities on the chuck.
