How much impact does laser cutting machine have on plate shearing machine? In recent years, a large number of laser cutting machine manufacturers and sellers have sprung up to occupy the market. As a result, the market of CNC shearing machine is shrinking. Even some users think that laser cutting machine can completely replace plate cutting machine. Can laser cutting machine really replace high-precision guillotine shear machine?
Precision Sheet Metal Cutting can be replaced by Laser Cutting Technology?
First of all, we need to know what type plate shears will be replaced.
What kind of sheet metal shears will be eliminated?
CNC Hydraulic Plate Shearing Machine:
Belong to the linear cutter machine, mainly used to cut the linear edges of various sizes of metal plates. Widely used in steel rolling, automobile, ship, tractor, bridge, aircraft, electrical appliances, instruments, boilers, pressure vessels and other industrial sectors.
Laser Cutting Machine:
Use the focused high power density laser beam to irradiate the work piece, which makes the irradiated material melt, vaporize, ablate or reach the ignition point rapidly. At the same time, it uses the high-speed air flow of the coaxial beam to blow off the molten material, so that the work pieces cut off.
However, the incision used for laser tailor welded blanks needs a high straightness. Using high-precision plate shears to cut is more suitable for the requirements of modern production. It not only improves the working efficiency. It is more safe and reliable. Moreover, the production cost greatly reduced. Also, it has the characteristics of energy saving, pollution reduction, easier use and maintenance.
Laser cutting machine and guillotine shear machine have their own disadvantages, so how can we choose to maximize the benefits?
Firstly, we should choose according to the industry. By contrast, laser cutting machine can cut out any abnormal shape and save labor. When it processes 1-3mm thin plate, the cost utilization maximize. The precision range of high accuracy shearing machine is about 0.03mm/m. Laser welding shall not exceed 0.1mm. So high precision guillotine shears are suitable for laser welding. And its cutting speed is several times faster than laser cutting machine.

The high-end CNC hydraulic guillotine shear machine will not be replaced by laser cutting machine. No matter in terms of accuracy or speed, precision high-end CNC plate shears are far higher than ordinary laser cutting equipment. In addition, the laser cutting machine generally only has about 1/3 smooth shear band. The others are tear band, with larger straightness, error and larger burr. Therefore, the shearing accuracy is not high. Generally, the cut sheet metal needs to be reprocessed.
