The difference between laser engraving machine and mechanical engraving machine

Many people are often confused when buying an engraving machine and wonder what is the difference between a laser engraving machine and a CNC engraving machine. In fact, the broad definition of CNC engraving machine includes laser engraving machine,laserpecker 2 laser engraver which can be configured with laser engraving head. Therefore, they are both related and different from each other, as well as many differences. Next, we will share with you the differences between these two devices.

First of all, both laser engraving machine and CNC engraving machine are controlled by computer numerical control system.laser pecker 4 First you need to design the engraving file, then open the file through the software to start the CNC programming. Once the control system receives the control command, the engraving machine starts to work.

The difference between laser engraving machine and mechanical engraving machine is mainly reflected in the following aspects:

1. Different ways of working:

A laser engraving machine utilizes the heat generated by the laser to engrave material.laser pecker pro It emits laser light and focuses it to a high energy density through an optical circuit system. The light generated by the laser can cause chemical and physical engraving marks on the surface material, or it can burn off certain materials to reveal patterns and text that need to be etched.

Mechanical engraving machines, on the other hand, rely on an electrical spindle to drive a high-speed rotating engraving head. Depending on the configuration of the material to be processed, the cutting tool mounted on the host table can engrave a variety of flat or three-dimensional patterns designed by the computer. It can carry out automatic engraving operations of graphics and text.

2. The mechanical structure is different:

Laser engraving machines can be divided into various types of specialized machines according to their specific purposes. The structure of these types of specialized machines is more or less the same. For example, the laser source emits the laser light and the CNC system controls the stepping motors, which move the focusing point to the X, Y, and Z axes of the machine through the light head, reflector, lenses, and other optical components, thereby ablating the material for engraving.

The mechanical engraving machine has a simple structure. It is controlled by a computerized numerical control (CNC) system that automatically selects the appropriate cutting tool for the X, Y, and Z axis processing machine.

In addition, the cutter of the laser engraving machine is a complete set of optical components, while the mechanical engraving tool is a variety of solid engraving tools.

3. The processing precision is different:

The outer diameter of the laser beam is only 0.01 mm. In the narrow, fine parts, the laser beam can be smooth, bright engraving. However, the mechanical cutter is not capable of such a task, because the diameter of the mechanical cutter is 20 times larger than the laser beam, so the CNC engraving machine is not as accurate as the laser engraving machine.

4. Difference in processing efficiency:

Laser is very fast, 2.5 times faster than CNC engraving machine. Since the laser can complete the carving in one go, so the CNC needs to be completed in two parts. In addition, the energy consumption of laser engraving machine is lower than CNC engraving machine.

5. Other differences:

Laser engraving machine is characterized by non-pollution and high efficiency; while CNC engraving machine is noisy and will cause pollution to the environment.

When using non-contact laser engraving machine, there is no need to process the workpiece; while CNC engraving machine belongs to contact processing, the workpiece needs to be fixed.

Laser engraving machine can process soft cloth, leather, film and other materials; while CNC engraving machine can not process these materials, because it can not fix the workpiece.

For carving non-metallic sheet and high melting point of the material, the laser engraving machine is more effective, but only applies to the plane engraving. The mechanical engraving machine, on the other hand, can produce three-dimensional works such as relief sculptures, although its shape has limitations.
