Fiber Laser Cutting Machine

Nowadays laser cutting machine is more and more widely used, as it is with high speed, high precision and automation. It can save manpower and improve production efficiency.  The laser is shot from laser generator, through optical system, focus to high power and density laser beam. The beam shoots on surface of workpiece and makes it reach melting point or boiling point, at the same time, the high pressure gas which is on the same axis with laser beam blow the melting or pneumatolytic metal away. That is the basic reason of laser cutting. According to the laser generator, there are two types – CO2 type & fiber type. The frequency of the CO2 laser requires higher wattage of lasers to penetrate through metals. CO2 laser systems are best suited to cutting wood, acrylic, plastic, and fabric.  Fiber laser cutting machine  is much more energy saving. In the situation that reaches same performance, whole fiber cutting can save around 70% energy than CO2 type. The wattage can...

6mm Hydraulic Shearing Machine With Estun E21s

6mm is a common thickness in sheet metal manufacturing. 6mm  hydraulic shears  is also a popular size in shearing machine. GLDMA can offer 6mm*2500mm, 6mm-3200mm, 6mm*4000mm, 6*5000mm different sizes of worktable, to satisfy variety of plate cutting demands. GLDMA Q12K series swing shearing is standard with Estun E21s system, which can control backgauge and the ordinary motor or frequency converter. Finished parts count and 40 program store functions can support common cutting task much more continuous, so that improve daily producing efficiency and save labor cost. There are also other advanced  shearing machine controller  to choose, like Estun E200ps, Delem DAC 310s. E200ps can realize servo control on X axis (backgauge), the cutting speed and precision are in a higher level. DAC 310s is with control of blade clearance, and the program storage is improved to 100 steps each. Client can choose the suitable model based on their own requirement and budget. 6mm hydra...
