What is the difference between shearing machine and laser cutting machine?

The shearing machine cuts sheet metal, plates, bars, and tubing of various cross-section into pieces by subjecting to shear force. It typically uses a punch and a die, which may be of any shape that is similar to a pair of scissors. Both the shearing machine and the laser cutting machine can shear the plate.

What is the difference between shearing machine and laser cutting machine?

Laser cutting machine is a piece of blanking equipment, which can cut boards of any shape, including straight, line and curve, holes and complex geometric figures. The laser cutting machine uses a focused high-power density laser beam to irradiate the workpiece to quickly melt, vaporize, ablate or reach the ignition point of the irradiated material. At the same time, the molten material is blown away by the coaxial high-speed airflow of the beam to cut workpiece. The incision of laser cutting machine is high but small without burrs. The cutting speed is based on the thickness of the steel and the power of the laser.

Shearing machine is a straight-line machine, which is mainly used to cut the straight edge of various sizes of metal plates. Although shearing machines are also blanking equipment, they perform simple shape cutting. Shearing machine is widely used in various industrial sectors such as steel rolling, automobiles, ships, tractors, bridges, airplanes, electrical appliances, instruments, boilers, and pressure vessels. The steel plate cut by the shearing machine has low degree, large cut and high roughness with burrs at a slow cutting speed. The cutting quality decreases more according to the thickness of the material.

What is the difference between guillotine and swing-type plate shearing machine?

The guillotine shearing machine is used in industries such as automobiles, tractors, rolling stock, ships, motors, and instruments. It is also suitable for stretching work of various high-strength alloy plates. The guillotine shearing machine adopts an integral welded-frame structure and has vibration treatment so that is has good rigidity, high precision and good precision retention. A three-point supporting shaft rolling guide rail is adopted that the upper tool holder rolls between the rolling guide rails without gap. The lifespan is determined by turning the hand wheel. The movable blade base and the four-edged long blade are convenient to adjust the uniformity of the blade gap, improving the cutting quality and extending the lifespan. The guillotine shearing machine uses tandem cylinder synchronization system with even force. By adjusting the flow rate of the tandem cylinders, the shearing angle can be easily to meet the needs of different shear plate thicknesses.

The swing-type plate shearing machine is used in the stretching, bending, extrusion, forming and other processes of metal sheets in the power industry and aviation industries. Compared with guillotine shearing machine, swing-type plate shearing machine mostly adopts oblique-blade, which is widely used due to simple structure, low failure rate, and high efficiency. As the tool holder rotates, the shearing angle and gap will change.

Which shearing machine can be viewed as high quality?

Relying on the guide rail, the shearing machine can realize intelligent movement. The cutting length and thickness are not limited by the size of the shearing machine. Even the guide rail can be lengthened as needed.

The shearing machine replaces manual feeding and adopts heavy-duty robots, which can load 5 tons at a time. It saves manpower and effectively avoids safety accidents.

The shearing machine has zero loss during the cutting process. The feeding platform can automatically flip the steel plate. In addition to eliminating manual operations, it also avoids the material waste caused by the long steel plate. During the operation, no pollutants are generated.
