Laser cutting machine compared with punch

- Jul 29, 2019-

    The laser cutting machine has high degree of flexibility in laser cutting, fast segmentation speed, high production efficiency and short production cycle, which can win a wide market for customers. Moreover, laser cutting has no cutting force, no deformation, no tool wear and good material adaptability. Whether it is simple or complex parts, it can be laser-precision and rapid prototyping. Its slit is narrow, cutting quality is good, automation is high, operation The control is simple, the labor intensity is low, and there is no pollution; the automatic cutting and nesting of cutting can be realized, the material utilization rate is improved, the production cost is low, and the economic benefit is good.

    The technology has a long effective life, and most of the plates that are currently more than 2 mm abroad are mostly laser-cut. The punch has more flexibility in the curve processing. One punch can have one or more sets of square, round or other special requirements punches, and some special sheet metal workpieces can be processed at one time. The most common one is In the chassis cabinet industry, the processing technology they require is mainly straight, square holes, round holes and the like, and the pattern is relatively simple and fixed.

    They mainly face carbon steel plates of 2mm or less, and the width is generally 2.5m×1.25m. Stainless steel (stainless acid-resistant steel) with a thickness of 1.5mm or more is generally not used because of the too high viscosity of the material. The advantage is that the processing speed of the simple pattern and the thin plate is fast, and the bad place is that the capacity of the thick steel plate is limited. Even if the punching is performed, the surface of the workpiece is collapsed, the mold is required, the mold development cycle is long, the cost is high, and the degree of flexibility is not high enough. Foreign steel cutting of more than 2mm generally uses more modern laser cutting instead of punching. The surface quality of a thick steel plate is not high when punching and shearing. The second thick steel plate requires a punch with a larger tonnage, which wastes resources. When the steel plate is thick, the noise is too high, which is not conducive to environmental protection.
