Main Characteristics:

  • Superb quality of laser beam,constant BPP within all the ranges of laser powers,so that long focus can still get pretty small laser spot.

  • Special wavelength(1070nm), having special capability of cutting highly-reflective materials,such as aluminium, cooper and brass,etc.

  • electro-optical conversion efficiency of laser supply>25%, much more efficient than CO2(<10%), so that consumption of electricity has been depleted very much.

  • Laser is transmitted by fiber cables, almost no consumption during transmission.

  • Modular design, “using immediately after plugging in”, mini size,easy to be installed, no maintenance of laser supply and transmission system of laser beam.

  • Life span of pumping source >100,000 hours

Spare parts

Highly-bright broadband single core semiconductor laser supply, much more than 100,000 hours of pump time. Every pump source is independent,so if one of them is broken, laser supply can also work normally, but the laser power will be a little reduced.

The gas is needed,when laser supply is working. And the reflective lens must be changed.

Laser cutting head

Using CypLite fiber laser cutting head,which has Z axis follow-up function. Highly sensitive and follow-up cutting head applies capacitance sensor monitoring, offering automatic adjusting function with stable and fast cutting.All kinds of matching design of nozzle are applied to lens with many focuses and can also be equipped with optical lens with different focuses. The focus and nozzle can be adjustable flexibly, including adjusting lens on X-Y direction and nozzles on the same axis.

Lathe bed 

SK - QF500 series cutting machine lathe bed part completely independent research and development, by the party tube welding lathe bed base, through the large gantry milling machine.
For large machine tool lathe bed we have many years of experience in processing, each lathe bed will be placed 30 days to 45 days after rough machining natural failure, the internal stress release completely again after finishing, ensure the machining accuracy.

  

Each factory lathe bed and guide rail at a distance of 2.5 meters, the parallel degree is less than 0.02 mm.Have a solid bed, to ensure efficient, high precision cutting speed!

Control box


The control box of fiber laser cutting machine is configured separately to reduce interference and easy to maintain.
To ensure the stability and avoid signal interference,we use the following measures based on electrical technology :
1. The main circuit and control circuit are connected by wires separately bypass.
2. The wire of main controller use shielded or twisted wire.
3. The connection of motor and driver use separate outlet to avoid parallel with other wires.
4. I/O interface chip、controller、sensor and the connector are as close as possible.
5. The connect wire between upper and lower equipment use the Aerial plug connector and Weidmuller terminal block.

Safety Protection System

The laser radiation have some damage on the human body which make the protection of the whole system very important

  • Laser module protection

  • The laser module have warning sign to introduce the laser out avoid harm from direct laser;

  • The cover have ground connection to avoid hurt from leakage.

  • The operator need to wear suitable laser protection glasses throughout the operation;

  • Make sure the protection equipment have no wear and tear before operating;

  • Do NOT look the laser out head at any time when the device is powered;

  • External Transmission fiber Protect section

  • The workstation of external transmission fiber ,use imported high quality guide pulley and Limit device to fix and guide laser cable;

  • The transmission fiber have protective cover made of special laser protection material to prevent the laser leak;

  • The protective cover of transmission fiber have leak sensor,if the fiber fractured to cause the laser leak,the sensor will transmit the signal to control center immediately,then the control center will stop the laser equipment and alarm.
