Are engraving machines and CNC engraving and milling machines twin brothers?

    In the 21st century, it entered the information industry society. CNC equipment is an indispensable mechanical equipment in the machinery industry. The most used ones are engraving machines and CNC engraving and milling machines, but most customers cannot distinguish the carvings.

The difference between the engraving machine and the CNC engraving and milling machine is always mistaken for the same mechanical equipment. People intuitively feel that the small format is the engraving machine, and the large-format engraving and milling machine, or the engraving machine, the router

Or simply called the large CNC engraving machine. In fact, they are two types of machines with different structures. Let's compare the two to see where the differences are embodied.
    The same thing: the working principle is basically the same, all driven by X, Y, Z three axes, controlled by the electronic controller.
The difference: from the use: the engraving machine is mainly used for the engraving of the plate, a large number of two-color plate or acrylic engraving, the depth of the engraving is about 0.5mm-3.1mm.

It is more common in the application of signs and signs. From the perspective of mechanical construction, the design of the CNC engraving machine is light, the X and Y axes move at a fast speed, and the Z-axis stroke is short, which is suitable for engraving materials of 4mm-9mm.

The engraving spindle head is equipped with a spring pressure nose, which is used to flatten the sheet material below 3.2 mm during the engraving process. The engraving spindle is connected to a larger diameter motor via a belt to increase the rotational speed.

The quality of the engraved workpiece is smoother. The engraving tool used is long, with a length of about 16.8 cm and a diameter of about 4.25 mm. Due to design constraints, the engraving machine is suitable for cutting

Small, high-speed engraving process.
    In contrast, the engraving and milling machine can be understood as both fine engraving and cutting and boring. For example, doing three-dimensional engraving, although the drop is very large, 205mm wide material can be completed at one time, one infeed amount

When big. The cutter diameter for the engraving and milling machine is from 1mm to 16mm, and the tool length is 45~85mm. We can use it flexibly, work with fine knives, and work with thick knives. Due to machine design

Focus on heavy-duty load, large steel frame and large Z-axis stroke, so it can not only be used as a small CNC engraving machine, but also can cut thick plates at high speed. The amount of one-time feed can reach 19.8mm-30.5mm.

This is a process that the engraving machine can't do at all.
   Although the engraving machine and the CNC engraving and milling machine have so many differences, the two complement each other, one is good at processing large pieces of material, and the other is unique in fine material engraving. and so,

Everyone should consider the size of the material to be processed when purchasing the engraving machine. Choosing the right engraving machine can be handy and let the machine create more benefits. Is just getting in touch

Laser engraving machine production processing steps?

1. Double-click to open the engraving software and set the layout according to the material size in millimeters.

2. Edit the file in the space area of ​​the page.

3. After making the file, place it in the position of the material to be processed to generate the desired processing path.

(1) The 2D path is two-dimensional engraving. Generally, the engraving depth of the two-dimensional engraving is fixed, that is, according to the engraving depth of the design, the milling process is performed from the surface of the object, and finally the ideal effect of the design is achieved. The specific operation is as follows: point 2D pop-up two-dimensional engraving mode dialog box, select "intaglio" in the "engraving depth" to set the depth to be processed, and select the tool compensation. The engraving method selects “horizontal milling bottom” to select the knife through the tool magazine, and the secondary machining method selects the hook edge, and also selects the same knife through the tool magazine. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersection ring, point to complete the path creation, then the computer automatically calculates the path, which is the green part. (Note: If there is no required tool, fill in the corresponding parameters in the "Tool parameters" column, click "Add tool" - "OK". This will add a tool).

(2) 3D path is three-dimensional engraving, three-dimensional engraving, which means that the system automatically changes the depth of engraving according to different graphics and tools, ensuring that the engraved surface is consistent with the design object. Commonly known as the "three-dimensional clear angle" function. The specific operation is as follows: point 3D pops up the 3D engraving mode dialog box, and selects the depth of the "inscription" in the "engraving depth". Remove the checkmark in front of the "rough knife milling". In 3D finishing, the tool is selected by the tool magazine, and most of the centering tools are selected. Select counterclockwise, and select the automatic check error and automatic decomposition self-intersecting ring, and click to confirm the completion path creation.

(3) The word cutting path actually refers to cutting the object to be processed from the engraving material by using a milling cutter. The usual processing methods are processing on the inside and outside contours. The “outer profile” is cut along the outside of the designed graphic. The cut part is the designed figure. The "inner contour" is cut along the inside of the designed pattern. The part left is the graphic designed. When the inner and outer contours are being cut, the Wentai system automatically sorts them and counterclockwise and clockwise directions. “Original line output” means that the design graphic is output as it is, and single line words and graphics must be output as they are.

Operation mode: Select the contour according to the need, use the outer contour when cutting the word, use the inner contour when hollowing out, or use any contour when using the center sharp knife when 3D inverted. The depth of engraving is generally 0 when cutting, the knife is on the table top; when it is inverted, set the depth according to the need, the knife is on the material. Select tool compensation. Use the same hour hand when making the panel and the bottom plate.

4. After checking the correct path, click the “Save engraving path” pop-up window. When the “lifting knife distance” is cut, the material thickness is increased by 7~9. In the “output only selected part”, check the number and click “Output file”. Find", select the Chunlan disk location to be saved after popping up the dialog box, select "G-codefiles(*.nc)" after "Save Type", enter the file name after "File Name", and click "Save" to return to the window. , click "Confirm".

5. Open the "Engraving Machine Control System", click "Open and Load" under the "File" menu to find the saved file name in the pop-up box, and click "Open".

6. Click “Simulation” and right click in the blue area. Select “Adjust to Window Size” and you will see the opened content and check if it is the desired one.

Note: Make a mark at the position of the workpiece origin when starting machining.
