Hand engravingĀ is the process of using a variety of engraving knives to carve a desired pattern into a metal surface. There are three types of hand engraving, and you can choose to use the most primitive engraving knives - chisels and small hammers. Alternatively, you can use a push type engraving knife for engraving. Lastly,Ā there is the pneumatic engraver, which is powered by compressed air and is a great time and labor saving engraving tool.
The shape of the engraving knife itself, as well as the subsequent use of the tool, will have a varying degree of influence on the pattern that is engraved. Angle adjustments can carve lines of different thicknesses. Different shapes of engraving knives can also carve different shapes of patterns. For example, pushing the corner of a square shaped engraving knife into the metal will result in a V-shaped groove. In addition, there are many other shapes of engraving knives. If you are interested, you can search for some related articles on the Internet to help you learn more about the specialized knowledge of engraving knives. However, the types of engraving cutters that are more commonly used today are the flat-bottomed engraving cutters as well as the V-shaped engraving cutters.
The most primitive method of carving
If you want to use the original method of engraving, then you will most likely need to use a small hammer with theĀ engraving knife. You need to hold the carving knife in one hand, and with the other hand, you need to hold onto the hammer and gently tap the carving knife so that the carving knife can carve out the desired pattern on the metal. Alternatively, if you don't want to use a hammer as an aid, there is another type of carving knife that you can use, and that is the push type of carving knife. In using this, you just need to clutch the carving handle and then push the knife towards the metal. If you want to carve sources or curves then you can use the engraving knife in a rotating manner. If you want to draw straight lines, then you just need to press your hand against the carving knife and then push it forward with some force. As for what kind of force to use, it all depends on what kind of depth you want to carve the straight line. However, when performing the above operation, you'd better use a vise or other fixtures to fix the metal firmly. Otherwise, you may subsequently hurt your hand.
Specific use of pneumatic engraving machine
Pneumatic engraving machines work on an air-driven principle, so some pneumatic engraving machines come with their own air compressor, while others require an external air compressor. Pneumatic engravers have a small piston inside the engraving handle. This piston works in much the same way as the small hammer mentioned above. The small piston will constantly hit the front half of the engraving knife and the engraving head will vibrate. In fact, the method of using the pneumatic engraving machine is similar to the method of pushing the engraving knife, except that the pneumatic engraving machine takes less effort and saves more time to use.
Tips for carving
In order to minimize mistakes in engraving and to produce better work, the engraver will use a pen or other marking tool to mark the metal in advance to define the lines and depth of the pattern to be engraved. Generally speaking, the markings made on the engraved metal are similar to the patterns drawn on sketch paper.
What are the methods of engraving?
- Brinotecnologia
The Brillo technique is simply a pointillism technique. The term first appeared in Italian and originally meant "a small, stowed carving knife". It simply means that thousands of dots or lines are poked into the metal, and these dots or lines can be contrasted to form an engraved pattern.
- Bank note style
Bank note style refers to the engraving of thousands of lines of varying lengths on metal, again using the shades of the lines to create contrasts between light and dark. The reason why this method is called Bank note style is because it was first used in the printing of banknotes.
Differences in the different shapes of engraving tools
Engraving tools come in many different shapes, and it is often up to the engraver's imagination to visualize what the engraving tool will actually do. Therefore, a good engraver has a very methodical imagination. In addition to the shape of the engraving head, sometimes using the same engraving tool at different angles can have many different effects. In addition, the use of engraving tools still requires a certain amount of experience. In the process of carving need to maintain the right strength, so as to ensure that the carving out of the cut surface is flat and smooth. If the strength of the use of too much or too little, in the carver is likely to appear raised burrs. So if you want to master a skillful carving technique, the time spent during this period is quite a lot. However, if you have a talent for it, you may master the craft faster.
Centuries have passed and the basic operation of hand carving has not changed much. But with the development of science and technology, carvers have more tools that can help them save time and effort. For example, they are able to use computers to draw intricate patterns and lasers to engrave high precision designs. There is also the use of pneumatic engraving machines, which have engraving handles that are almost the same size as the old engraving tools, making them the best choice for many engravers when engraving.
