1. What kinds of carving tools are there?
1, the blade of the flat knife is straight, which is mainly used to chop and smooth the concave and convex on the wood surface. Large models can also be used to chisel large scales with a sense of block. If used properly, such as the brushwork effect of painting, it looks very strong and vivid. The acute angle of a flat knife can carve lines, and when two knives intersect, the toe of the knife can be removed or the pattern printed. Woodcarving figures in Sweden and the Soviet Union mostly use flat knives, which have a strong flavor of wooden knives.
2. The blade of triangular knife is triangular, because its front is on the left and right sides, and the sharp point is on the middle corner. To make a triangular knife, you should choose a suitable tool steel (generally 4-6 mm round steel), mill out a triangular groove of 55 -60 degrees, grind the waist flat, and grind the mouth end into a cutting edge. When the angle is large, the score line is thick, and vice versa. Triangular knives are mainly used for carving hair and decorative lines, and are also commonly used tools for printmaking and watermark wood carving. When manipulating, the triangular tip pushes on the board, and the sawdust spits out from the triangular groove, and the lines are depicted in the parts pushed by the triangular tip.
3. The cutting edge of the medium steel knife is straight and both sides are inclined, so it is also called "printing knife". Traditional carving thought: the blade of Sinosteel is right in the middle, which can keep the front and back, so that the nearby departments will not be shocked. Medium steel knives are also used to print patterns on characters' costumes and props.
4. The cutting edge of the round knife is arc-shaped, which is mostly used for round and round dents. It is also useful in carving traditional flowers. For example, the round surface of the leaves, petals and branches of flowers needs to be conformal with the round knife. Horizontal transportation of round knives is labor-saving and can adapt to ups and downs and small changes. Moreover, the line of the round knife is uncertain, so it is flexible to use and easy to grope. According to different uses, the models of circular knives should be different, and the size range is basically between 5 cm and 0.5 cm.
5. Jade Wandao, commonly known as "monk's head" and "butterfly chisel", has an arc-shaped cutting edge. It is a polishing knife between a round knife and a flat knife, which is divided into two types: arc and oblique arc. When the flat knife and round knife can't be used, they can be replaced. It is characterized by gentleness, neither as straight as a flat knife nor as deep as a round knife, and is suitable for concave ups and downs.
6. The oblique angle of the blade of the oblique knife is about 45 degrees, which is mainly used to chamfer and polish the seam corners and hollowed-out gaps of the works. If you carve the corner of a character's eye, an oblique knife is better. Knives are divided into forehand oblique cutting and backhand oblique cutting to adapt to all directions. In boxwood carving in Shanghai, hair strands are generally carved with oblique knives, which are carried by choking, so the effect of hair carving is more vivid and natural than that of triangular knives.
Second, the choice of carving tools skills
1. When purchasing carving tools, you must be familiar with the choice of blade length of woodworking engraving machine. The choice of cutter blade length should be to increase the thickness of the processed plate by 2-3MM, which is the most suitable cutter blade length. The rotation speed of the cutting acrylic motor is 18000-24000 rpm, and the blade length is too long, so it can't be used to process hard materials.
2. When purchasing, different carving objects will lead to different woodworking carving machines. When carving fine words and patterns, you should choose tools with small angles and small tips. When carving Daimonji patterns, try to choose tools with large angles and sharp tips without affecting the accuracy requirements. When designing the carving path, try to maximize the cutting angle and the tip of the knife to improve the carving efficiency. The carving material should be hard, the angle of the material should be large, and the tip of the knife should be large.
3. The carving knife of woodworking engraving machine is frequently broken, which is not only related to the quality of the knife. It also has something to do with your carving habits, the precision of the guiding motor, plate and fixture of the engraving machine.
4. On the issue of choosing carving tools, the staff must understand that the low-power spindle motor (with a small fixture) uses a small handle tool (3. 175mm, 4.0mm), and the cutting speed should not be too fast, so as to maintain the minimum resistance during high-speed milling and obtain the best cutting effect, and the high-power motor can use a large handle tool to improve the carving speed.
