Engraving machine carving notes

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.

Woodworking engraving machine use: temperature control and water pump

    Woodworking engraving machine is a kind of machine that is often used in the field of woodworking engraving. In addition to woodworking engraving, it is also used in the field of advertising production. Some manufacturers will choose to use the engraving machine, but as a kind of machine, it has some precautions when it is used. Today, Xiaobian will tell you about the use of this engraving machine in temperature control and water pump.
    When designing such a machine, woodworking engraving machine manufacturers will have a pump design, which is designed to control temperature. Why has to be this way? Because the engine and power of the engraving machine are relatively large, it is a medium and large machine. If there is no pump design, the temperature of the machine will become high during long-term use, which will damage the machine and cause the machine to malfunction.
The water pump in the engraving machine should maintain a certain temperature line. If it is lower than this temperature line, stop the operation of the machine in time, then wait for cooling and replace the water in the pump. That is to say, if the temperature of the engraving machine is found to be high when using the engraving machine, heat dissipation is required. Therefore, every time you use the machine, check whether the pump of the machine is normal, and the amount of water stored in it is enough to operate normally. Only in this way can you reduce the chance of machine failure during use.
