CNC engraving machine and laser engraver are computer engraving machine, CNC engraving machine refers to CNC router, CNC routing machine, CNC engraver, or CNC carving machine, laser engraving machine refers to laser engraving machine, You need a computer to control the carving. After computer typesetting in advance, the prepared picture file or path map is imported into the machine. From this point of view, both belong to machines. Although both use numerical control systems, they work in different ways and have different mechanical structures. In contrast, the structure of CNC engraving machine is relatively simple. Through the control of the computer numerical control system, the machine automatically selects the appropriate drill and tool to engrave along the X, Y and Z axis of the machine tool.
Many people always mistake CNC engraving machine and laser engraving machine for one thing. In fact, there are many differences between the two machines.
Define
Laser engraving is based on numerical control technology, and laser is the processing medium. The laser source launches the laser, and the CNC system controls the laser head and the motor to move the laser head, mirror, lens, etc. on the optical element, so that the focus moves the axis of the machine tool on the X, Y, and Z axis. The processed material is immediately illuminated by a laser. Physical modification of melting and gasification for machining purposes.
Sculpfun S30 Pro Max laser engraving without contact with the surface of the material, not affected by mechanical movement, the surface will not deform, generally do not need to be fixed. Not affected by material elasticity and flexibility, convenient for soft materials. High machining precision, fast speed, wide application fields.
CNC is the abbreviation of Computer Numberical Control, which is an automatic machine tool equipped with a program control system. The control system can logically process the program with control code or other symbolic instructions, and decode it, so that the machine tool moves and machinates parts. CNC engraving machine is a kind of electric tool that completes engraving through CNC controlled machine tool.
Methods
The Sculpfun laser engraver uses a laser to change the material through high temperatures. Therefore, similar to combustion, different materials of different materials will produce different combustion chemical reactions during the working process, which will vary according to the melting point of the material. The cutting effect is different, and soot and odor will also be produced in the industrial process.
The CNC engraving machine relies on the spindle and the drill bit to work, similar to the drill bit, which only produces a lot of dust during the working process, but does not produce smoke and odor.
Laser engraving is non-contact etching and can protect the surface of the engraved material from scratches. In addition, the laser beam is very thin, so the slit is small, suitable for precision cutting. The cutting seam of the CNC engraving machine depends on the diameter of the milling cutter. There are many types of router bits. Different milling cutters are used for different materials.
Principle
The Sculpfun S10 laser engraver focuses the laser emitted by the laser through the optical path system into a high power density laser beam. The laser beam illuminates the surface of the workpiece to bring the workpiece to the melting or boiling point. At the same time, a high-pressure gas coaxial with the beam blows away the molten or gasified metal. With the movement of the relative position of the beam and the workpiece, the material will eventually form a cut mark, so as to achieve the purpose of carving.
CNC engraving machines rely on high-speed rotating engraving heads driven by electric spindles. By means of tools configured according to the processing material, the processing material fixed on the worktable can be cut, and through automatic engraving operation, various 2D or 3D designs with relief graphics or text can be realized in the computer.
The biggest difference between laser engraving machine and CNC engraving machine is that the cutter of Sculpfun S9 laser engraver is a complete set of optical components, and the cutter of CNC engraving machine is a variety of solid fragments. Laser etching machine is the use of laser high energy to complete the cutting or engraving of the material, and CNC engraving machine is the use of high-speed rotating tool head to cut and engraving of the material, so these two forms of action on the carving object is different.
