First, the appropriate engraving tool should be selected according to the design pattern. There are many types of engraving tools, of which the diameter, length, and shapes are different. Single blade, double blade, flat bottom, pointed bottom and round bottom; diameter ranging from 3.175mm, 4mm, 5mm, 6mm, 8mm, 10mm etc. And then comes to cylindrical shape, V-shaped and slotted shaped etc.
Secondly, the long-term use of the engraving tool will cause itself to wear seriously and become blunt, resulting in a non-smooth cutting surface. Therefore, it is necessary to change the tool regularly to ensure a smooth cutting surface. It is advised to choose the right tool and carefully observe it during the engraving process. If the cutting surface is not smooth, please replace the tool in time.
