laser cutting machine aluminium

Laser cutting machine in order to faster processing parts have similarities, it is higher than the traditional processing efficiency.Laser technology is expected to reduce processing time and production capital.For a long time, in the 7000 series of aluminum processing, laser at always failed to play because of the decrease of fatigue performance.Recently, the laser system innovation makes people new to laser cutting machine aviation with aluminum is good at the assessments.Preliminary tests already said laser technology in the potential of the fuselage processing.Body system in the future as well as the existing design should not be ruled out due to the past experience of laser in the fuselage system may be used.We should maintain open attitude to study various conditions, to make sure can laser technology products with efficiency.

In the current system of laser cutting machine, the laser cutting machine used in aviation limitations are improved, these limitations include fatigue performance and create order in the number of gay.At present, laser systems in large standards reduce the size of the thermal interference zone (HAZ) and the corresponding haircuts.In laser cutting machine order, technical staff has been able to cutting parameters to carry out the manipulation, and use of calculator software to carry out accurate repeatedly.These technological advances allow for laser cutting machine can meet in the production of the fuselage structure from the new thought.The fuselage structure is important to create 7000 series aluminum material.

Can laser cutting machine is good at depends on news fast and accurate to the aluminum foil processing into different shapes, the technology is good at making laser cutting machine equipment just to carry out the commercial would attract more airlines.In the 1970 s, the creation of the important technology of laser cutting machine in the assessment, they discover, produced by the laser processing on fatigue properties of parts of haircuts hurt is not agreed.Potential weight hurt to create industry profits, makes the laser cutting machine technology is important fuselage create dealers on the shelf.

The creation of the rotating parts and transmission is adopted large metal forging billets.Fuselage also includes some parts adopt forging materials, however, the fuselage of several adopt aluminum parts.Traditionally, 7000 series zinc base alloy are used to carry out processing, this is due to the alloy has good static strength and fatigue strength.Although 7000 series aluminum material is suitable for the aviation to use, but they are not resistant to high temperature.News fast heating, such as welding and laser cutting machine operation, can cause micro cracks.Micro cracks caused the decrease of fatigue strength.Welding and laser cutting machine is produced two kinds of thermal processing of micro cracks.

Quality and process control is very important.Any given machining sequence must not sure factors with manipulated or rule out directly.In the past, laser cutting machine to different production batch quality control between and identity are required to take a huge challenge.

Fatigue fracture is usually formed in congregate stress, such as the edge of the parts, geometry changes, or joint.Sheet metal body parts, there are many different forms of joint, off many of the number of fatigue cracks formed in the joint.If didn’t have to be used for laser cutting joint holes, the edge of the laser is used in important parts as cutting.About other effects, and can be adopted to illustrate the most damageable connection position compared with joint, laser cutting machine are required to take haircuts and non important damage parts.In this way, we can draw the conclusion: if possible a part on the joint fracture, laser cutting machine like that technology does not know fatigue characteristics of further damage parts.The use of the aluminum.

Using optical fiber laser cutting processing of several important matters should be considered:

Fiber attenuation caused by coupling cannot be ignored.For example, in laser diode ignition, the laser diode and fiber coupling, the coupling between optical fiber and optical fiber, optical fiber and the coupling between igniter has saved the energy dissipation.

Adoption of optical fiber laser cutting process to consider some major matters.The first is the eye.Released by the light wavelength fiber laser system is harmful to the eyes, and should adopt the measures that shield an eye.Due to the technique present only less than 5 years, so fierce proposed a comprehensive training on the appropriate system control and safety.Many manipulation work without application of optical fiber laser cutting cutting experience, and therefore should be held after fiber cutting control system good initial training to compensate for the lack of experience.

Another necessary to pay attention to is to cut materials.Is fiber laser cutting is good at cutting big local data, but the class cannot be used for cutting acrylic or polycarbonate material, and can only limited application in the field of cutting wood or fiber materials.At the same time the application for determining when optical fiber laser cutting, the thickness of cutting data is a very main factor.Thicker material need more power cut, and these conditions, laser cutting may not be very good.Application at this time you can just install the optical fiber laser in plasma cutting head side effect.Before the fast, light switch to the plasma cutting, manipulation of workers can be applied to optical fiber laser cutting request tolerance small thin material.Even can be applied to two different cutting by cutting the same parts.Application, for example, manipulation of workers can pick the appearance of plasma cutting parts, laser cutting machine manufacturer in nanjing, then the application of optical fiber laser cutting internal shape.
