What is the smallest hole that a laser drilling machine can drill?

Laser drilling machine is a general term for laser equipment used to drill holes on the surface of materials. Laser drilling machine can refer to both laser marking machine and laser cutting machine. It uses the laser beam of a high-voltage heat source output by the laser to focus on the workpiece. On the surface, using the principle that the workpiece melts into holes instantly, small holes and micro holes can be processed on various metals, non-metals, and composite materials. As for the size of the holes that can be drilled by laser drilling machine and the thickness of the material, I will explain it in detail today.

Compared with traditional EDM drilling and mechanical drilling equipment, laser drilling has higher drilling accuracy and excellent drilling quality. The punching is smoother, without burrs and burrs around, more uniform, and has no restrictions on processing materials. It can be used for non-deformation drilling of any hardness material such as steel plate, stainless steel, aluminum alloy plate, cemented carbide, etc. It can achieve hole diameter: 1.00~3.00 (mm) Sub-small hole: 0.40~1.00 (mm) Ultra-small hole: 0.1~0.40 (mm) Micro hole: 0.01~0.10 (mm) Sub-micro hole: 0.001~0.01 (mm) Ultra-micro hole: 0.001 (mm) and other specifications of drilling. Of course, different models need to be selected to achieve different hole diameters.

Laser can drill the smallest holes, but it depends on the material itself. For metal products, 5-8mm holes can be drilled on them. Of course, the thinner the material, the finer the hole, and the thicker the material, the more expensive it is; laser drilling is burr-free, efficient, and fine. Generally speaking, the thickness of the material also determines the size of the hole, so the thicker the material, the more expensive the machine. The laser drilling machine is used to reduce the spot diameter to the micron level to obtain the laser power density. Such a high power density can be used for laser drilling on almost any material.
Compared with traditional processes, laser drilling has significant technical advantages. It has the characteristics of fast drilling speed, high efficiency and good economic benefits. Laser drilling is a vacuum non-contact processing that effectively avoids scratching the workpiece. It also reduces the cost of mold manufacturing. Using the built-in tracking sensor system to effectively maintain the height with the workpiece, the laser can work on irregular surfaces (bevel, diamond surface, etc.) without affecting the depth-to-diameter ratio. Laser drilling is still a fully automatic processing equipment. One person can take care of several devices. The processing will not cause pollution or harm. It is highly efficient and is the most mature and stable punching equipment.
