The comparison of laser cutting machine and punching machine

Laser cutting machine laser cutting high degree of flexibility, cutting speed, high efficiency, short production cycle, as the customer to win the broad market. Laser cutting without cutting force, surface machining deformation; No tool wear, good adaptability to materials; Whether simple or complex parts, can use laser rapid forming a precision cutting; Its narrow kerf width, cutting quality and high degree of automation, simple operation, low labor intensity, no pollution; Can realize automatic cutting layout, nesting, raising the utilization rate of materials, low production cost, good economic benefit. Its effective life time is long, the ultra structure of 2 mm plate abroad mostly adopts laser cutting. Punch have more flexibility in curve machining, a punch can be one or more sets of punch, round, or other special requirements, can work out some specific sheet metal artifacts, common chassis cabinets industry, they asked for the processing technology of main is linear, square hole, round hole cutting, such as fixed pattern is relatively simple. They mainly is facing the following 2 mm carbon steel plate, wide in 2. 5 m×1。 25m。 1 in thickness. More than 5 mm stainless steel due to material viscosity is too large compare fee mold, is generally do not use the punching machine. Its advantage is to simple graphics and plate processing speed is fast, the disadvantage is that when strong thick steel plate ability is limited, even can flush the surface subsidence, mold, mold development cycle is long, high cost, flexible degree is not high. Abroad more than 2 mm steel plate cutting processing is generally use more modern laser cutting, instead of using a punch, a thick plate punching and shearing surface quality is not high, when the second plate need larger tonnage punch, waste of resources, three blunt thick steel plate when the noise is too big, is not conducive to environmental protection
