Engraving is the technique of using a manual engraving tool or engraving machine to leave a special pattern on the surface of the engraved material. You can see engraving in many places, most commonly in jewelry. In addition, engraving is used to make printing plates. A printing plate is a tool that allows designs to be printed on paper. The designs that are printed on paper are also called "prints," and engraving is one of the oldest of the techniques used to make prints.
Tracing the historical origins of carving
According to authoritative sources, humans learned to carve at least 430,000 years ago. During the Paleolithic period, hand-carving of bones and ivory was seen as an important technical skill. Then later, humans began to paint on rocks. Today, in the twenty-first century, the uses of carving techniques are varied. Aside from engraving on jewelry, people also engrave personal information of the pet owner on tags they wear for their pets. It is also common to engrave the name of the recipient on trophies. There is also the printing industry where printed metal plates are engraved. In short, engraving will always be present in your daily life in various forms.
What are the different types of engraving?
1. Hand-carved
Hand carving is one of the oldest forms of carving and can be considered one of the most complex. Hand-carved pieces are usually hand-carved by artisans using small carving tools. Because the entire carving process is done manually, hand carving takes the longest time compared to other types of carving. Even though hand carving takes a long time, there are still many people who prefer this type of carving.
Compared to other carving methods, hand-carved pieces are not reproducible. Even if the same carver carves the same pattern, there will be slight differences in the details. Therefore, each hand-carved piece is unique and unrepeatable.
One of the oldest forms of hand-carving is "push carving". "Push carving" means that the carver pushes the sharp carving tool into the carving material with great force, eventually leaving a pattern on the carving material. However, this type of carving requires a certain amount of strength on the part of the carver, so this form of carving is not suitable for a long period of continuous operation.
2. Laser engraving
Laser engraving is a method of leaving an engraved design on an engraved material with a strong laser beam. The realization principle of laser engraving is that when a strong laser beam shines on the engraved material, the engraved material will be instantly vaporized due to the high heat generated by the laser.
Laser engraving is considered to be one of the most advanced engraving methods at present, and there are many materials that it can engrave. For example, wood, leather, acrylic, etc. are able to be engraved by laser. In our daily life, wooden picture frames, ipda protective cover, marble made coasters and pet name tags on these items of text or patterns may be engraved with laser engraving this engraving method.
Laser engraving can be divided into two types, one is deep laser engraving and the other is laser ablation. Laser engraving is known for its high efficiency in engraving, which can be said to be the fastest way to mark items. However, laser engraving can only be used to engrave some flat patterns, some three-dimensional patterns can only be completed by hand engraving.
3. CNC Engraving
CNC engraving refers to the use of a computerized machine to engrave pre-determined material on the engraved material.CNC engraving machines have a spindle for engraving and a drive system to drive the spindle. The CNC engraving machine is fully computerized and is capable of engraving quickly on the engraved material as long as the pattern is designed in advance on the computer.
CNC engraving is also very fast, so it is very suitable for use in the production of high-volume products. For example, plaques, pet name tags, and other items are all CNC engraved.The most widely used field of CNC engraving is industrial production.
4. Rotary engraving
Rotary engraving is a method of engraving on engraved materials using a machine similar to a motorized engraving head. Rotary engraving can penetrate basic engraving materials such as wood, or softer textured metals. Some rotary engraving machines are capable of engraving according to a program set up on a computer. So basically, they can reproduce the engraving pattern that the creator has designed on the computer one by one.
Rotary engraving is more efficient than manual engraving. Moreover, rotary engraving can be used to engrave special materials such as plastics, ceramics and glass.
5. Diamond knife engraving
Diamond cutter engraving can be considered another form of rotary engraving. This means that the engraving head of the machine used for rotary engraving can be replaced with a diamond cutter head. Diamond cutter engraving This method of engraving is mainly used for metal engraving .
It can even be argued that engraving in this way using a diamond cutter can be done on almost all bare metals, the common bare metal
This includes metals such as aluminum, brass, gold, and stainless steel. Some common items include watches, jewelry, and pens.
