CNC Router knowledge

CNC router include woodworking router, stone router, advertising router, glass router, laser router, and plasma router

CNC Routers and laser cutting machines, but they all have similar characteristics. Take advertising router as an example. From a functional perspective, computer router are divided into two categories: low-power router and high-power router.

A low-power CNC Router refers to a CNC Router with a small carving motor power (usually 80-200W), due to its carving motor power

The rate is small and can only be applied to fine machining with fewer cutting surfaces each time. For example: chest tags, sand table models, surface processing of handicrafts

Wait. This type of engraving machine cannot perform high-power engraving and cutting. A high-power CNC Router refers to a CNC Router with a carving motor power of over 700W. This type of engraving machine can not only perform low-power engraving, but also high-power engraving. For example, making crystal characters, various advertising signs, irregular cutting and forming of boards, processing of artificial stone, etc. Due to its high power, it can cut 30mm thick organic glass at once or use a molding knife for high-power molding carving.

The working principle of CNC engraving machine

The computer numerical control engraving machine is actually a three-dimensional numerical control system, and its working principle is shown in the figure:

A specialized design and typesetting software is installed in a general-purpose microcomputer for graphic and text design and typesetting, automatically generating machining path information. The tool path data is transmitted to the microcontroller through a USB interface or other data transmission interface. The CNC system receives the tool path data, completes a series of functions such as display and user interaction, and uses specific algorithms to convert the input path information into CNC information. The controller converts this information into signals (pulse trains) that drive stepper motors or servo motors, and controls the X, Y, and Z axes of the engraving machine. Simultaneously milling can carve various flat or three-dimensional graphics and text designed on the computer, achieving automation in carving.

Application fields of CNC router

1. Advertising and gift making industry, used for carving various types of two-color board signs, organic glass, three-dimensional billboards, two-color character statues

Embossed medals, organic board reliefs, three-dimensional door lettering, etc.

2. Model making industry, producing sand table models, house models, etc.

3. Mold making industry, including carving button relief molds, printing hot stamping molds, injection molds, stamping molds, shoe molds, etc.

4. Wood industry, used for relief pattern design and production.

Circuit fabrication, drilling, milling, etc. in the development of new printed circuit board products.

6. Seal industry, carving seals of various fonts and materials.

7. Electric discharge machining machine tool electrode engraving processing.

8. Mechanical processing industry, dial and ruler scales.

9. Processing of automotive industry, tire molds, car lamp molds, and decorative mold.

Moreover, with the continuous emergence of various new decorative materials, there are more and more materials that can be used for carving, which enables computer numerical control

CNC Routers have a greater potential, therefore, the application scope of computer numerical control CNC Routers will continue to expand.
