The difference between jade carving machine carving and hand carving.

1. Ultrasonic engraving technology: In order to improve the engraving efficiency, ultrasonic is generally used. This process uses a mold made of high carbon steel, and the machine drives the mold to vibrate and rub back and forth on the surface of the jade material at the frequency of ultrasonic waves. This method can quickly achieve the purpose of understanding and carving jade. This method only needs one mold to copy and paste jadeite, which naturally saves time and effort.

2, computer machine carving: computer machine carving also needs a template, first of all, there must be a sample model, after scanning with a machine, use this sample as a template, and then machine carving jade on the machine, through repeated carving, just like copying with a computer.

3, hand-carved, advantages: unique, spiritual, exquisite and beautiful. Disadvantages: Time-consuming, laborious and expensive. Jade carving is the most quintessential artistic means in China's crafts, including round carving, relief carving, general carving and so on, and there are countless ancient carvings. But today's hand carving is no longer "manual" in the traditional sense.

4. Nowadays, the so-called hand carving is a A Jin steel drill grinding head driven by a high-speed motor. Jade jewelry cut in this way is also very different from that cut by sculptors.

5. But at least this carving process still depends on the sculptor's hand drawing as a template, which has a unique personality. It also needs personal manual decoration to make jade ornaments look more spiritual, because such ornaments are often more popular with people.
