What is the difference between laser engraving machine and CNC engraving machine

    The most significant difference between the laser engraving machine and the CNC engraving machine is that the laser engraving machine adopts the laser melting method for manual engraving, and the CNC engraving machine adopts electronic information technology to manipulate CNC blade、laser head or ultrasonic head for manual engraving. The laser engraving machine can be a CNC engraving machine. The CNC engraving machine can also install a laser head to carry out manual engraving, so the two are intersecting. Let me tell you the specific difference between laser engraving machine and CNC engraving machine.

    Although both use CNC systems, they work differently and have different mechanical systems. In comparison, the structure of CNC engraving machine is relatively simple. According to the operation of the electronic computer numerical control system, the CNC engraving machine automatically selects the appropriate engraving tools and engraves them on the x, y, and z axes of the CNC machine tool.

    The structure of different types of laser engraving machines is basically the same. The laser source sends laser light, and the numerical control system controls the motor to move the laser head, reflective lens, bifocal lens, etc. on the photoelectric device, so that the focus point moves on the X, Y, Z  axis of the machine, thereby ablating the material.

    The big difference between a laser engraving machine and a CNC engraving machine depends on the fact that the special tool of the laser engraving machine is a set of detailed optoelectronic devices, while the special tool of the CNC engraving machine is a variety of solid line engraving tools.

Other differences:

    1: The laser manual engraving and polishing are carried out once, and the CNC machine is carried out twice.

    2: The diameter of the laser beam is only 0.01mm, the special tools for CNC machine are 20 times larger.

    3: The laser speed is 2.5 times faster than the CNC engraving machine.

    4: The energy consumption of the laser is less than that of the CNC engraving machine.

    5: The laser has no noise, zero pollution, and high efficiency; CNC lathes are noisy and pollute the environment.

    6: The laser is non-contact, and the product workpiece does not need to be fixed. The CNC machine is the production and processing of the capacitive grating, and the product workpiece is determined.

    7: The laser can produce and process soft raw materials, such as fabrics, leather products, plastic films, etc.; CNC machine cannot make this kinf of materials, because the product workpiece cannot be fixed.
