We supply the laser cutting heads with auto-focusing function and you can easily cut uneven surface me>tals. These cutting heads are compact stable and easy for use.

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.

High-power Nd:YAG Self-floating Laser Cutting Heads

There are following main features of our cutting heads:

  1. Suitable to1064nm 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 portcan 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.

High powerNd:YAGself-floating laser cutting head consists ofnozzle, focal lenses andauto-focusing system.

  • Nozzle: nozzle is very important for laser cutter. Through in-depth research and tests, we have obtained a large of optimal data according to the different customers’ requirements to recommend the best suitable nozzle.
  • Focal lens: in general, the focal lens system consists of a few lenses or non-spherical lenses. The focal length is longer, the focused beam diameter is larger, the power density is lower, but the depth of focus is longer, which is beneficial to cutting thick material.
  • Auto-focusing system: there is a capacitive sensor used to measure the distance between the nozzle and workpiece. The measured distance will be online fed backed and then the system will drive the step motor or servo motor to adjust the distance and always keep the distance same.
