Product Introduction

We supply the laser cutting heads with auto-focusing function andyou 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.

2. High-powerNd:YAGSelf-floatingLaser Cutting Head

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.

3. STC5 FiberLaser Cutting Head

STC5 series cutting head is a newly designed cutting device for fiber lasers. A fully closed-loop control method with high performance capacitive sensor enables STC5 to be a cost effective solution, which demonstrate an impressive auto-focusing features to enable the cutting machine to process any sheet surface waviness.  Besides common communication port, STC5 is equipped with Ethernet port in order for real-time height detection, step piercing, leapfrog, pen-up height presetting, constant optical path compensation, extraordinary fast response time, and dual closed servo loop of speed and position feedback.
