Everything You Need To Know About Laser Drilling

The laser hole drilling technique is one of the fast and precise ways of creating various types of holes with different geometries. The machine can quickly drill every material, ranging from the softest to the most fragile.

The process leverages thermal energy from the laser light to cut out shapes and holes on the workpiece. The traditional drilling process uses a rotating physical drill cut to drill holes in the workpiece. Laser drilling micro holes technique does not create swarf-like components compared to other drilling processes.

The laser drilling technique has no continuous beam to cut holes into materials. Instead, it uses pulses of laser light. The laser light will burn and vaporize the unwanted piece from the workpiece to have the desired result. The laser machine can quickly drill holes in any type of material.

Some of the modes of laser drilling include:-

  1. Trepanning

Trepanning is one of the modes of laser drilling, with an original hole quickly drilled on the workpiece. After the gap has been drilled into the material, a laser beam is then passed over the material to achieve the desired spot. The process will end up cutting the site rather than drilling it—trepanning results in unique holes with large diameters. One of the drawbacks of trepanning is that it is slower than direct drilling.

  1. Percussion drilling

The percussion drilling will pass laser beams at a fixed position on the material. The pulses will flow consistently, hence removing the tiny layers of the workpiece to deepen the hole. This drilling mode is ideal for high-quality, small-diameter holes with high aspect ratios.

  1. Direct drilling

The direct drilling technique creates a hole in one laser pulse. It is one the fastest methods, but it gives a substantial degree to the hole taper.

Some of the benefits of laser drilling include:-

  1. Versatility

The laser drilling technique has a high aspect ratio. The laser beams do not encounter any frictional resistance. The optical configuration and the workpiece’s dynamics can restrict the drill’s depth. 

  1. Applicability

The capability of the laser beams to remove materials from the workpiece depends on the absorption rate of the target material. With this, it becomes much easier to get the right wavelength. Some lasers drilled materials include wood, rubber, and even ceramics.

  1. High accuracy

The laser drilling technique achieves high accuracy since it is an automated process. The buyer can easily select the desired wavelength, which tends to have low absorption in the landing workpiece and high absorption in the target drill workpiece.

Final words

The laser hole drilling technique is widely used in the manufacturing industry, such as in the medical industry and electronics. The above article has illustrated some of the modes of laser drilling and the benefits of laser drilling techniques. Laser drilling has a higher initial investment cost than other drilling processes, which is worth the investment. This is because they offer high efficiency and effectiveness in the drilling process.
