Applied Materials and Fields:This machine is specially designed for jewelry laser welding, which is mainly used in jewelry patching holes and blister repairing. Laser spot welding is one of the most important applications for material processing technology. The procedure of spot welding belongs to heat conduction type, that’s to say the laser radiation heat the surface of the work piece, the heat on the surface spread toward inside by heat conduction. By controlling the parameters as width, energy, peak power and repeat frequency, etc. of the laser pulse, work piece will be melted and formed special molten pool. Due to the particular advantage, it has been successfully used in processing gold and silver jewelry as well as welding tiny and small parts.  Product Features:l Energy, pulse, frequency, spot size, etc. are adjustable in a big range to realize various welding effects. The parameters are adjusted by the controlling rod inside the enclosed cavity.l Adopting British imported ceramic laser pump cavity which corrosion resistant, high temperature resistant with high photoelectric conversion rate. The lifetime of laser pump cavity is 8-10 years, and the lifetime of xenon lamp is over 8,000,000 times.l Adopting the most advanced automatic light blocking system in the world to eliminate the stimulus to eyes caused by light.l Able to work continuously for 24 hours, stable work performance for the whole machine.l Humanization design and ergonomic, not tired after long time working.l Main advantages: fast speed, high efficiency, large in deep, tiny deformation, small HAZ (heat affected zone, high quality welding, no pollution for welding spot, environmental friendly very much.  View Details

Adjustment of Laser Cutting Machine Precision 2016-07-22

After Laser Cutting Machine is used for a period of time, the focal length will gradually change, resulting in certain error in the cutting accuracy. Perfect laser will introduce essential knowledge of laser cutting machine--commissioning operation accuracy 1. A light spot of the laser beam focus is transferred into the minimum when the burst is established at first, by the effect of spot size to determine focal length.As long as the laser light to the minimum, this position is the best processing focal length, and then... After Laser Cutting Machine is used for a period of time, the focal length will gradually change, resulting in certain error in the cutting accuracy. Perfect laser will introduce essential knowledge of laser cutting machine--commissioning operation accuracy 1. A light spot of the laser beam focus is transferred into the minimum when the burst is established at first, by the effect of spot size to determine focal length.As long as the laser light to the minimum, this position is the best processing focal length, and then began to work 2. In the first part of the laser cutting machine debugging, can use some adjustable accuracy test, to determine the focal length of the workpiece scrap burst.Move up and down the laser head height, laser spot size will burst when there is a change of different sizes.The optimal position of the focal length and the laser head is determined by adjusting the position of the different position for several times. 3. Laser cutting machine in the installation is completed, will be in the numerical control cutting machine cut mouth upload a line device, through the scribe device to draw a simulation cutting graphics, analog graphics for the 1m square.Built in a diameter of 1m of the circle, the four corners are drawn on the diagonal.After the draw, with measuring tool to delimit circle and square is four edge tangent.If the square diagonal length is 1.41M, the central axis of the circle should be divided into the side of the square, and the distance between the point of intersection of the central axis and the two sides of the square to the intersection of the two sides should be 0.5m.Test the distance between the diagonal and the intersection, you can determine the cutting accuracy of the device.
