60W Qishi laser engraving machine can engrave Taihang stone in relief, and it takes more than 20 minutes to engrave 5mm depth. As long as you have a laser marking machine, you can use it to make money. For example, you can use the laser marking machine to engrave text and patterns on various materials in your own shop, workshop, home or even a street stall. It can be customized in batches and you can make a lot of money in one day. Do you want to own a laser marking machine that can make money? You can purchase from me for wholesale or retail.
