Laser drilling is an early practical laser processing technology, and it is also one of the main application fields of laser processing. With the rapid development of modern industry and science and technology, more and more materials with high hardness and high melting point are used, and traditional processing methods can no longer meet certain technological requirements. Machining tasks of this type are difficult and sometimes impossible with conventional machining methods, but are not difficult to achieve with laser drilling.
Laser Drilling Machine
The laser beam is highly concentrated in space and time. Using the lens to focus, the spot diameter can be reduced to the micron level to obtain a laser power density of 105-1015W/cm2. Such a high power density can be used for laser drilling in almost any material, and compared with other conventional drilling methods such as mechanical drilling and EDM, it has the following significant advantages: 1) Laser drilling is fast and efficient. high and economical. Since laser drilling uses a high-energy laser beam with a power density of l07-109W/cm2 to act on the material instantaneously, the action time is only 10-3-10-5s, so the laser drilling speed is very fast. High-efficiency drilling can be achieved by combining high-efficiency lasers with high-precision machine tools and control systems, and through program control by microprocessors. Compared with EDM drilling and mechanical drilling, the efficiency of laser drilling on different workpieces is increased by 10-1000 times.
Compared with the traditional drilling process, the laser drilling machine has the following advantages:
(1) The laser drilling speed is fast, the efficiency is high, and the economic benefit is good.
(2) Laser drilling can obtain a large aspect ratio.
(3) Laser drilling can be carried out on various materials such as hard, brittle, and soft.
(4) There is no tool loss for laser drilling.
(5) Laser drilling is suitable for the processing of a large number of high-density group holes.
(6) Small holes can be machined on the inclined surface of difficult-to-machine materials by laser.
(7) Laser drilling has simple requirements for workpiece clamping, and it is easy to realize online and automation on the production line.
(8) Laser drilling is easy to punch holes in complex shape parts, and it can also punch holes in vacuum.
There are various types of spare parts for laser cutting machines. Today, let's take a look at the maintenance spectacle lenses in laser cutting machines. The maintenance of the spectacle lenses is to prevent dust and slag from splashing out and destroying the focal point spectacle lenses.
