Use of X-ray Nondestructive Inspection Machine

X-ray nondestructive inspection machine is very versatile, the advantage is also very obvious, in the case that can not damage the test object, it can determine the state of the measured object. Specifically, X-ray nondestructive testing equipment used mainly three:

1.Identify the quality of the workpiece by X-ray nondestructive testing equipment, whether the parts within the workpiece are defective, whether the welds meet the labeling requirements, and whether there is any defects inside the workpiece. Through the X-ray nondestructive testing equipment to test the finished product quality and yield.
2.Determine the shape and size of the workpiece, also can accurately show the measured the discontinuous position of the workpiece;
3.The sensitivity of X-ray non-destructive testing equipment is high, so it can directly detect the state of the workpiece, such as the location of the workpiece defects, size, and the severity of damage, etc., it is also possible to determine the defect repeatability of the workpiece.

The Laser Cutting Machine Improves The Cutting Quality - Auxiliary Gas Pressure

The laser cutting auxiliary gas can play a heat, fire or combustion and blowing off the role of fouling for laser cutting machine, so as to get a better cutting effect. Different types of gas, cutting speed and effect are different. In general, the faster the cutting speed of oxygen, the better the nitrogen cutting effect, the lowest air cutting costs.
1.high air velocity on the entire area of the cooling effect can be enhanced, making the cutting speed slow down.
2.the impact of intermittent shock waves in the air on the cooling of the laser, uneven air pressure and temperature will lead to cutting speed decline.
3.the convergence of the laser beam can affect the auxiliary gas, occurs focusing or beam dispersion, resulting in the decline in laser cutting speed, affecting the cutting effect.
Therefore, in the use of auxiliary gas for cutting, we should pay attention to control the auxiliary gas pressure, to avoid cutting speed, affecting the cutting effect.

The Daily Maintenance of Laser Cutting Machine

1.Laser cutting machine radiation self-protection.
After the movement of the system for a long time, the movement of the joints of the screws, coupling will produce loose, which will affect the smooth movement of machinery, so in the machine running, observe the transmission parts are abnormal or abnormal phenomenon, found that the problem should be timely and maintenance. At the same time the machine should be a period of time with a tool one by one solid screws. The first reinforcement should be made after one month.
2.Optical path inspection
The laser engraving machine's optical path system is completed by the the reflection of the mirror and focus of the focus Lens, there is no problem of the focusing lens in the optical path, but the three mirrors are fixed by the mechanical part. It is recommended that the user must check whether the light path is normal.

The Unique Advantages of Laser Marking

Laser marking technology solves a series of problems of the traditional printing technology. It is characterized by high precision marking, fast, stable performance. And only through the computer control and simple operation, it can print a variety of complex patterns, text, two-dimensional code and other content, in full compliance with the existing PCB industry high-quality marking requirements.
Compared with the traditional printing technology, laser marking technology has a variety of advantages of performance:
1.Good quality, strong wear resistance. PCB board surface marking is clear and beautiful, you can mark a variety of LOGO, pattern, two-dimensional code and text, the pattern is directly engraved on the material.
2.Good quality, strong wear resistance. The laser beam emitted by the laser is focused by a minimum spot diameter of up to 10 μm has a small benefit in dealing with complex graphics and precision machining.
3.High efficiency, simple operation, reduce costs. Users only need to set the parameters on the computer, which can directly marked in just a few seconds to ten seconds to complete the material surface mark.
4.Non-destructive marking. Laser marking use non-contact processing, laser head does not need to contact with the material surface.
5.Safe and environmentally friendly. A variety of thin metal / non-metallic materials can be marked;
6.Stable performance, long service life. With the development of technology, laser service life increased significantly, equipment life greatly extended.

Factors Affecting Cutting Quality of Laser Cutting Machine - Cutting Speed

The optimum cutting speed range can be determined according to the equipment description or the test. The cutting speed is also changed due to the material thickness, material, melting point, thermal conductivity and melting surface tension.
1. the cutting speed is inversely proportional to the density and thickness, it is proportional to laser power density, 
2. the cutting speed is too fast so that the cutting line energy is lower than the required amount, the seam can not quickly melt the melt melt immediately blown to form a larger drag, with the incision slag, the incision surface quality decreased.

3. when the speed is very low, because the incision is too wide, the arc will even go out. It can be seen that good cutting quality and cutting speed are inseparable.
