How to solve the problem of ultra-fine hole drilling in materials

Ultra-fine hole laser drillingDue to the special material, if the punching machine used in the past is not well controlled, the punched holes will appear flat holes, polygonal holes and other non-round holes, and the holes punched are not smooth and the burrs are large. Some of them need secondary processing before they can be used. In the past, the drill bit required for mechanical drilling, but the disadvantage of the drill bit is that it will break and damage the aluminum plate during drilling.

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

In the past, the difficulty of ultra-fine hole laser drilling was that the thin aluminum plate would deform during the processing, the drilling diameter would be inconsistent, the taper would be too large, and the area around the hole would be too rough.

Solve the pain points of Ultra-fine hole laser drilling:

1. Now the technology of laser drilling machines is getting better and better. It can not only drill holes, but also cut and weld multi-functional laser all-in-one machines. Laser drilling uses a high-performance laser beam with a power density of 107-109W/cm2 to instantly drill holes in aluminum plates, which only takes 10-3-10-5s. Laser drilling does not require the drill to contact the aluminum plate, and the thermal deformation is extremely small, which solves the problem of aluminum plate deformation in traditional mechanical drilling.

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

3. The laser drilling machine can perform fine drilling and cutting on various materials such as hard, brittle, and soft, so even the special thin aluminum plate material business is quite simple. The thin aluminum laser drilling machine has no problems such as tool wear and replacement, no mechanical deformation, and is easy to maintain; it is equipped with efficient protection and emergency stop devices. When the laser water cooling system fails, the equipment automatically cuts off the power supply, and the safety risk of the operator is reduced to ineffective; the special machine customization capability is strong, and special machines can be tailored according to customer needs.

The ultra-fine hole laser drilling machine has a very fast drilling speed. The efficient laser is combined with high-precision machine tools and control systems, and program control is performed through a microprocessor to achieve efficient drilling.
