How do woodworking engraving machines extract image outlines?

When the hand-held engraving machine is used to open the edging groove, the instrument must be firmly fixed. The guitar, mandolin and table piano can be fixed directly with the clamp. You can also screw some wooden blocks around the body on the workbench, and then Prepare some wedge-shaped thin plates or chips to quickly clamp the body between the block and the body. If it is to squash the ordinary shape of the guitar body, you can fix a multi-layer board on the side of the workbench. The clip that can get stuck in the waist of the body can also do most of the edging work.

Use a caliper to carefully set the depth of the engraving machine, and then find a piece of scrap to check the trimmed groove and the side strip you intend to use.

When the long fiber is cut radially to cut the body of the wood, it is easy to pull out the burr. For example, when the guitar body is opened with a groove, the four areas marked by the arrow are easier to pull out the burr. The four areas should be chamfered first, that is, the engraving machine is pulled along the direction of the head to grasp the wood. When viewed from the front of the body, the engraving machine moves clockwise. This way, the wood can be prevented from being pulled out. glitch.

The safest method of slotting is to perform down-cutting (clockwise) in the direction of the arrow in the direction of the four arrows. After completing the four areas, the groove of the entire body is completed in a counterclockwise direction. Therefore, the edging knife will not have the problem of pulling out the burr when passing through the previously slashed area.

If necessary, after the slotting with the engraving machine, the raft can be used to trim the unsmooth part of the groove.

Many years ago, most of the handmade piano makers used the hand-held engraving machine to complete the operations, and most of the studios now use the engraving machine workbench - from heavy industrial equipment to small workbench. It is used. It is really better to finish the opening groove on the engraving machine table than the hand engraving machine.

Reverse the head of the engraving machine fixed under the workbench to pry the surface of the workbench from a hole in the workbench. The side of the body that needs to be grooved moves toward the workbench. The method of avoiding pulling out the burr and the hand-held engraving machine The operation is the same, and because the engraving machine is fixed and you can move the body with a much lighter weight with both hands, the flexibility of the body control is much better.

If you want to slot a curved body such as a mandolin or a curved guitar, using an engraving machine table is a good solution for a small studio. Use a double-sided glue on the cutter hole to make a wooden ring of the appropriate height. Raise the body to a suitable height and keep the side of the body perpendicular to the table. Use a shaft clamp with a smooth bottom to clamp around the body to stabilize the body at an appropriate height. The shaft clamp prevents the edging The position of the clip can be changed when the knife is used.

Stone engraving machine chooses what to pay attention to

    When choosing a stone engraving machine, the choice of the knife is very important. As the saying goes, if you want to be good at work, you must first sharpen its tools. If you choose a good knife, then the effect of carving will be very good. Today, Xiaobian will come to you, how to choose the engraving machine's carving knife, will be more in line with the standards and requirements.
    First of all, the stone engraving machine manufacturers suggest that when you choose the engraving machine to cut the knife, you can choose the multi-headed knife. Such a knife will be more suitable for the actual operation of the engraving machine. Because of the multi-headed knives, when engraving, it can be carried out at the same time, and it can work at the same time, which greatly improves the efficiency of the work and makes the engraving work more suitable.
    Secondly, when choosing a knife, you should choose a knife that can adjust the speed. Such a knife will be adjusted according to the actual situation, such as the strength of the sculpture, the quality of the stone, etc., so that the engraving work can be smoothly carried out smoothly.
    More importantly, this kind of knives can adapt to the engraving stone by adjusting the rotation speed when using it. Therefore, when encountering a relatively hard stone, when the engraving, the rotation speed will be reduced, thereby reducing the wear of the knives and making the engraving machine The knives have a long service life and at the same time reduce the loss of the engraving machine itself. Therefore, Xiaobian compares and suggests that it is more appropriate to choose this type of carving knife.
