How to solve various pain points of ultra-fine laser drilling

Ultra-fine hole laser drillingDue to the particularity of the material, if the drilling machine is not mastered well in the past, the holes punched will appear flat holes, polygonal holes and other non-round situations, and the burrs of the holes punched are very large, and drilling is required. In the past, mechanical drilling had to use a drill bit, and drilling into a bad place would damage the aluminum plate during the drilling process.

In recent years, as people have higher and higher requirements for the quality of drilling processing, traditional mechanical processing methods can no longer meet the requirements of various drilling speeds, quality, and depth-to-diameter ratios. Especially for the punching and cutting of thin plates, the requirements are getting higher and higher, and laser punching can meet the special requirements of various processing. Due to the advantages of high efficiency, low cost, and good comprehensive technical and economic benefits, pulse laser punching has become the preferred equipment for ultra-fine hole laser punching and cutting.

In the past, the difficulty of ultra-fine hole laser punching was that the aluminum sheet would deform during processing, the punched hole diameter was not consistent, the taper was too large, and the area around the hole was too rough.

How to solve the various pain points of ultra-fine laser drilling?

1. The technology of laser drilling machines has become better and better. It can not only perform drilling, but also integrate cutting and welding. It is a multi-functional laser all-in-one machine. High-performance laser beams are used to instantly drill holes on thin plates. The power density is 107-109W/cm2/cm2, and the drilling time is only 10-3-10-5s. The laser beam does not need to contact the aluminum plate during drilling, and the thermal deformation is extremely small. Therefore, the deformation problem of thin aluminum plates in traditional mechanical drilling is solved.

2. Laser drilling machine High-performance laser drilling equipment has fast processing speed, high efficiency, small straight cutting seam, smooth cutting surface, and can obtain a large depth-to-diameter ratio and depth-to-width ratio. Therefore, the aperture of the laser punched in the thin aluminum plate is uniform and consistent in size. The punching size of the thin aluminum plate of 0.2 mm is about 0.05, which can achieve an error range of plus or minus 0.01mm.

3. The laser drilling machine can perform fine drilling and cutting on various hard, brittle, and soft materials, so even the special material drilling of thin aluminum plates is quite simple. The thin aluminum plate laser drilling machine does not have problems such as tool wear and replacement, no mechanical deformation, and easy maintenance; after the laser water cooling system fails, the equipment automatically cuts off the power supply, reducing the safety risk of the operator to zero; the special machine customization capability is strong, and exclusive models are tailored according to customer needs.
