Laser Processing Equipment

The control system is based on PC and provides the following:

TV-channel enables receipt on SVGA monitor live videopicture of the object for orientation of the workpiece followed by inspection of the processed hole diameter.

**) Drive:
5-coordinate step drive with feedback on a position controlled through Pentium IBM PC

Laser Treatment System is designed for broaching profile channels (holes) in hard and superhard materials, such as natural and synthetic diamond, ruby, hard allows, aluminum ceramics, etc.

Using this technology profile channels (holes) which meet strict requirements to surface geometry and roughness are processed during one completely automated laser treatment operation, and there is no need to reset a part processed.

The primary application is to broach profile channels (holes) in diamond and diamond-like dice used to produce metalcords, cable wires, and other products made by drawing through the grooved die holes.

The technology covers practically the whole diameter range of industrial diamond dice from 0.1 to 5.0 mm. The accuracy of treatment is 2% of die diameter. The attainable accuracy of treatment in finishing mode is 3 mm.
The system is also suitable for die repair (profile channel boring), products treatment around the inner and outer contours. Laser marking of die frame surfaces can be operated as well. Combined laser and TV channels enable receipt on SVGA live videopicture of the object for orientation of the workpiece and further inspection of treatment quality and processed hole diameter.
A solid-state Nd:YAG  laser with Q-switch is used in the system as a laser source. Service life of laser heat is at least 10000 hours. Service life of pump lamp is at least 400 hours.

Laser power supply and cooling unit contains the system for selection and stabilisation of cooling water temperature. This allows to maintain the average power of laser radiation at high stability level. Interlocks of minimal flow of the cooling water and of its max temperature allows to enhance  reliability and service life of the laser.

The Laser Treatment System is controlled by IBM PC. Working program is made both with the use of own graphics editor and AUTOCAD editor. The computer allows to automatically select an optimum travel algorithm and the laser Q-switch control depending on the thickness of the processed material, its shape and contour of laser processing.
