The main disadvantage of laser cutting is the high power consumption. Industrial laser efficiency may range from 5% to 45%. [19] The power consumption and efficiency of any particular laser will vary depending on output power and operating parameters. This will depend on the type of laser and how well the laser is matched to the work at hand.
Milling with a laser is a three dimensional process that requires two lasers, but drastically cuts costs of machining parts. [2] [7] Lasers can be used to change the surface properties of a workpiece. The appliance of laser beam machining varies depending on the industry. In light manufacturing the machine is used to engrave and to drill other ...

It was established in Karachi in 1968, the facility was built for the local manufacture of machine tools under technical cooperation and technology transfer agreements with Oerlikon-Bührle of Switzerland .
Laser types with distinct laser lines are shown above the wavelength bar, while below are shown lasers that can emit in a wavelength range. The height of the lines and bars gives an indication of the maximal power/pulse energy commercially available, while the color codifies the type of laser material (see the figure description for details).
Laser marking on stainless steel A laser engraving machine A laser engraver. A laser engraving machine consists of three main parts: a laser, a controller, and a surface. [2] The laser is a drawing tool: the beam emitted from it allows the controller to trace patterns onto the surface.
