Guaranteed laser lifetime makes 50 000 hours with no maintenance involved. Should laser become out of order, Lascom service engineers will come and have the laser replaced. Lascom has extensive information about 500 laser types produced by IPG Photonics. Each of these lasers has a life time above 50 000 hours. Since the moment of the first laser table delivery, only one laser has ever become out of order. However, after a quick repair, the laser was back to work in normal operation.
The laser removes coating with a speed of 8 m/sec on straight lines and 360 mm²/sec on flat areas. When laser technology is compared with the traditional method of acid etching in similar conditions, the speed of removal by laser can be up to 15 times higher.
Regardless of fast speeds, cut-offs accuracy is rather high. The width of a cut off can be adjusted from 50 micron (optionally from 35 micron) up to a few mm. Moreover, the coating can be removed completely on surface areas up to hundreds of square mm. In the air a cut off 0,5 mm wide withstands 1 kilovolt with no electrical breakdown. When a part of a construction (e.g. laminated glass), a 0,05 mm wide cut-off withstands 600 Volts due to the complete coating removal with the help of the laser. At the same time the surface of the glass remains intact.
High productivity and accuracy brings the cost of products down. Moreover the number of personnel involved in the process is also reduced. Only one operator is needed in order to run a line for heated glass production.
Unlike the traditional acid etching method, laser production is absolutely harmless for an operator, which is undoubtedly another important advantage. The harmlessness of laser production is attested to by the results of the testing laboratory.
