Laser cutting machine quality appraisal

laser cutting machine is a high-tech production equipment that uses a laser beam as a "cutting tool" to cut materials. The laser cutting machine consists of a laser generator, optical path system, CNC workbench, etc. It can accurately control the movement of the laser beam to achieve fast and accurate cutting of the workpiece. The working principle of
laser cutting machine is that the laser beam emitted by the laser is focused by the optical path system to form a high-power density beam, which is irradiated onto the surface of the workpiece. When the workpiece absorbs the energy of the laser beam, its surface temperature rapidly rises to the melting point or boiling point, causing the material to melt, vaporize or ablate. At the same time, the high-speed airflow coaxial with the beam blows away the melted or vaporized material, thereby forming a kerf on the workpiece.

1. Classification according to laser output power: low-power laser cutting machine, medium-power laser cutting machine, high-power laser cutting machine. Laser cutting machines with different powers have different application fields.
2. Classification according to the type of cutting material: metal laser cutting machines are used to cut metal materials, and non-metal laser cutting machines are used to cut non-metal materials.
3. Classification according to the format of cutting boards: generally divided into standard format laser cutting machines and non-standard ultra-large format laser cutting machines. The X-axis cutting length of ultra-large-format laser cutting machines is mainly above 8000mm.
4. Classification according to the geometric shape of the cutting plate: cutting plates can be divided into plane cutting and three-dimensional cutting. Flat plates are generally cut by plane laser cutting machines, and three-dimensional plates can be cut by robot laser cutting machines, three-dimensional five-axis laser cutting machines, etc.
5. According to the laser type of the cutting machine, it can be divided into fiber laser cutting machine, CO2 gas laser cutting machine, and YAG laser cutting machine.

quality product dispute situation:
According to the situation reported by the client and the information provided, the client signed an "Order Order" with a machinery company (hereinafter referred to as the supplier) to purchase a set of "laser cutting machines" involved for metal cutting. During the production process, the client discovered that the cutting machine had large deviations in diagonal accuracy, positioning errors occurred when the machine tool moved, no response signal in plasma cutting (line damage), the system could not be started, machine accuracy was inaccurate, there were gaps in the transverse motor, and the cutting circle was not round, etc. Later, a machinery company adjusted the diagonal accuracy and improved the circle cutting.
In order to further clarify the cause of equipment accuracy failure, the client hopes to conduct a quality analysis on whether the "laser cutting machine" involved has quality problems that cause the accuracy to not meet the standard.
quality analysis results: The
quality analysis expert group discussed the relevant information and on-site investigation and inspection of the "laser cutting machine" involved and conducted a comprehensive quality and technical analysis, and made the following suggestions and conclusions:
involved The side straightness of the main rail, the longitudinal horizontality of the auxiliary rail, and the flatness between the main and auxiliary rails, which are related to the installation accuracy of the "laser cutting machine" guide rail, are out of tolerance, and do not meet the installation accuracy requirements; the diagonal deviation and side length deviation of the steel plate products after cutting by the cutting machine are out of tolerance, and do not meet the technical index requirements for comprehensive accuracy.
