What are the advantages of the laser cutting machine automatic focusing head?-Cathy

It is believed that anyone who has been in contact with a laser cutting machine will know that the positional control of the focus of the laser cutting device at work is critical. Focus control refers to the laser cutting machine in cutting different materials and different thickness of the plate. In order to achieve a better cutting effect, operator should set the focus of the laser beam in different places.  This is what we call focusing. With the breakthrough of industrial control technology, the automatic focusing cutting head can be indispensable in laser cutting automation.

In the early days of laser cutting applications, manually focusing is the main way. With the development of laser technology, the auto-focusing gradually eliminate this manual focusing method. People began to realize the benefit of the auto-focusing function slowly.

The bottom of the laser cutting head is a nozzle. During the cutting process, the nozzle height is constant, so lifting the cutting head is a way to adjust the focus. The focal length of the focusing mirror is immutable. So focusing by changing the focal length is impossible. If the position of the focusing mirror determine the focus position. When lowing the focusing mirror, the focus is lowered, and when raising the focusing mirror, the focus is raised, which is a way of focusing. By using a motor-driven focusing mirror for up and down motion to achieve the automatic focusing.

     Another method of autofocusing is to place a variable curvature mirror before the beam enters the focusing mirror. By changing the curvature of the mirror, changing the reflecting beam divergence angle to change the focus position is possible.

With the auto-focus function, the machine can automatically adjust the focus to the appropriate position when machining workpieces of different materials and thicknesses. Which can significantly improve the processing efficiency of the laser cutting machine, and greatly reduce the slab perforation time. Therefore, for the laser cutting machine, the auto focus function is an important and indispensable function.
