  • Blade replacement techniques for guillotine shears


    The blade sharpening and replacement skills of the guillotine shears, the blades must be sharpened regularly. If sharpening is not performed for a long time, it seems to be trouble-free, but in fact it will cause a lot of waste. If the blade is cut blunt and continues to cut, the outer grain structure of the blade will be destroyed due to excessive pressure, which will damage the equipment and fail to obtain good shear quality. After the blade is sharpened, the damaged crystalline outer layer is

  • Mechanical Compensation and Hydraulic Compensation Technology of Press brake

  • Cut a good workpiece with a laser cutting machine


    Since the laser power density has a great influence on the cutting speed, the choice of lens focal length is an important issue. After the laser beam is focused, the spot size is proportional to the focal length of the lens. After the beam is focused by a short focal length lens, the spot size is smaller, and the power density at the focal point is higher, which is beneficial for material cutting; but its disadvantage is that the focal depth is short and the adjustment margin is small.
