Laser based Diamond Processing System

Lasers are used in the diamond processing industry to :
 

• Kerfing 
• Sawing
• Shaping

The diamonds are mounted on a die or plate, which in turn is mounted on an XY table. Focussing of the laser is achieved by moving the focussing lens fitted on the Z axis. Typically, the motors used on the XY table are 5 phase step motors, DC or AC servo motors, or Linear motors.

The quality of the finished product ( measured by weight loss and surface finish ) is affected by: 
 

• Quality of laser
• Smoothness of movement of the XY table
• Motion pattern programmed by the software

3 axis PC-based motion controller
