In the early application of fiber laser cutting machine, due to the lack of automatic focusing, laser cutting machine needs to be manually focused; this focusing method not only has certain requirements on the operator's technical level, but also has a certain impact on product accuracy and productivity.

      In the product accuracy and productivity also has a certain impact.

Fiber laser cutting machine auto focus and manual focus which is better?

　　With the continuous improvement of production requirements, the new auto-focus laser head was introduced, the traditional manual focus laser head is gradually eliminated, the new auto-focus laser head is widely used.

　　The perforation focus of manual focus cutting head can not be adjusted, the perforation focus is the same as the cutting focus, when cutting thick plates, the punching energy is not enough, and the punching time is long.

      When cutting thick plates, the punching energy is insufficient and the punching time is long. Auto-focus cutting head has adjustable perforation focus, which can be adjusted to increase the perforation energy when perforating, and can increase the perforation speed when perforating thick plates.

　　In terms of perforation time, auto focus is more than twice as fast as manual focus, the cutting effect is basically the same, but auto focus will reduce the sheet over-melting phenomenon due to the short time of material overheating, the advantages of auto focus are obvious.

      The advantages of auto focus are obvious; it can significantly improve productivity and greatly reduce the perforation time for cutting thick sheet materials, and can process different materials and thicknesses of workpieces. The machine can also quickly adjust the focus to the right position.

　　Therefore, auto focus fiber laser cutting machine is ahead of manual focus in most aspects, with the progress of science and technology, auto focus laser cutting machine will be more practical, processing effect is more perfect.
