High-power Nd:YAG Self-floating Laser Cutting Head
We supply the laser cutting heads with auto-focusing function and
you can easily cut uneven surface metals.

Laser cutting head is one of most important parts of laser cutting machines. The traditional cutting head
only includes focusing lens and nozzle and does not have auto-focus function. If there is no auto-focus,
the spacing between the focus lens and workpiece will not be same, which results in different focused
beam diameters and then different power densities at different positions. Thus the cutting quality may
be different at the positions.
Based on the requirements from the market, we have developed self-floating laser cutting heads. By
using capacitive sensor and auto motor moving system, the spacing between the focus lens and
workpiece will be kept same at any position of the cutting field. The response time is millisecond range
only and the system is stable and reliable.
There are following main features of our cutting heads:
1) Suitable to 1064nm wavelength YAG laser cutting system.
2) Suitable to laser power less than 1000W.
3) Spacing between the exit of the nozzle and workpiece is 1-20mm adjustable, response time is less
than 5ms, and the control precision is 0.2mm.
4) Independent, complete Z-axis control and adjustable focus position. Also there are some functions
such as automatic/manual mode, up/down jog control, auto tracking/auto reset function, multiple gap
setting, zero shift compression etc
5) Numerical control port can easily be connected to most controllers. The cutting system automatically
tracks the marking head open, close or back to zero.
6) Multiple focusing lenses with various focal lengths.
7) Cooled nozzle design used for high pressure cutting.
8) Over travel protection, collision protection and power-off protection etc.
Structure Description
High power Nd:YAG self-floating laser cutting head consists of nozzle, focal lenses and auto-focusing
system.
