Combining unit equipment provides interesting results

A scanner is normally used in order to allow for implementation of the high repetition rates of the USP laser. But with GL Trepan, its energy can also be transferred to the workpiece efficiently at slower travel speeds. The trepanning optics can also be used in combination with the galvo scanner in order to reproduce the general slow wobble or spiral movement of the galvanometer drives through the spiral drilling optics and to utilise the high jump speed of the scanner effectively. This allows for the manufacturing of hole patterns at the required dimensions with high speed and fast machining. This process is used primarily with very thin materials with a machining time of a few milliseconds.

Cutting speeds up to 200 mm/min

GFH said its laser machining centre can cut ferrous and non-ferrous metals as well as non-metallic materials up to a thickness of 1 mm. “The speed primarily depends on the desired contour and surface quality,” the company noted. “For a copper-beryllium workpiece with a thickness of 0.12 mm and high cutting quality requirements, for example, a speed of several hundred mm/min can be achieved.”

It added that 0.2 mm-thick stainless steel can be processed at a solid 60 mm/min. “Thus, the time required for laser micro-cutting is significantly lower than that of comparable processing with wire-electro discharge machining.” Moreover, the versatile options for setting trepanning and focusing with regard to the cutting gap diameter, cutting angle, speed, focusing lens, and cutting nozzle allow for easy adaptation to the respective application and therefore economical production of even low piece counts, according to the manufacturer.
