The main consumables in the application of stone cnc router machines: engraving knives, generally round knives and flat knives are commonly used. The differences are:

Round knife of stone carving knife:

The cutting edge is arc-shaped, which is mostly used for round and round dents. It is also very useful in carving traditional flowers. For example, the round surface of flower leaves, petals and flower branches + needs to be shaped with a round knife.

The horizontal movement of the circular knife is less labor-saving, and it can adapt to large ups and downs and small changes. And the line of the round knife is not sure, it is flexible to use and easy to explore. According to different purposes, the model of the round knife should be different, and the size range is basically between 5 cm and 0.5 cm. The two corners of the knife edge for the round carving figure should be polished off to make it an arc shape. Otherwise, when the carving pattern or other dents, not only can not be pushed, but also the sides of the dent road will be damaged. If you are doing embossing, you should keep the two corners of the knife edge, and use the function of the corners to carve the corners of the ground, so two kinds of them should be equipped. There are also positive and negative differences for round knives. The bevel is in the groove and the back of the knife is straight. It eats more wood and is most suitable for round carving, especially in the stage of blanking and digging.

　　Flat knife of stone cnc router machine:

The cutting edge is straight and is mainly used for cutting and shoveling the unevenness of the wood surface to make it smooth and non-marking. The large model can also be used to chisel large, with a blocky surface, and use it well, such as the brushstroke effect of painting, to appear vigorous, vivid and natural. The sharp angle of the flat knife can engrave the line, and the knife foot or the pattern can be removed when the two knives intersect. The woodcarving figures in Sweden and the Soviet Union mostly use flat knives, which have a strong taste of wood knives. As the main consumable part of woodworking engraving machine, woodworking engraving knife occupies a relatively large cost in daily use. Therefore, the daily operation of the equipment is very important. For the same woodworking engraving machine props, pay attention to the operation and use of the woodworking engraving machine, the service life of the woodworking engraving machine props can be more than doubled.
