Overview
DMG MORI: varied laser technologies for different applications
The standard lasers used in DMG MORI CNC laser machines include fiber lasers (cw / qcw) and ultrashort pulse lasers, such as femtosecond lasers. Their short pulse frequency means the latter provide the added benefit of eliminating any heat input into the material being machined. This makes it possible to create delicate structures in a wide variety of materials, from carbides all the way to ceramics. DMG MORI uses these laser technologies in its Shape, Precision Tool and PowerDrill series.
Laser ablation with the LASERTEC Shape series
The laser machines of the LASERTEC Shape series provide process-reliable and reproducible laser ablation of surfaces of different thickness, fine contours, delicate cavities for the production of injection molds, press tools, inscriptions and other engravings with the utmost precision.
Thanks to the specifics of their laser beams (nanosecond or femtosecond lasers), the machines are able to effortlessly process tool steel or even highly wear-resistant materials such as carbides or ceramics, while simultaneously ensuring a perfect surface quality. The machines can work unmanned over several shifts or, if appropriate automation solutions are employed over entire weekends. The advantages of non-contact laser ablation technology truly come into their own through various application-specific software functions.
Machining of diamond tools with the LASERTEC PrecisionTool series
The LASERTEC PrecisionTool series takes laser machining for the production of precision tools to a whole new quality level. Conventional mechanical machining processes, such as grinding and eroding, have already reached their limitations due to the excessive process forces and negative thermal reactions in diamond cutting materials. This is where the innovative laser technology can demonstrate its unique strength and numerous advantages.
The machines in the LASERTEC PrecisionTool series are the most flexible CNC lasers for the machining of diamond tools available on the market. Depending on the machine type, machining operations can be carried out with a tool diameter of up to 360 mm for a maximum tool length of 410 mm. Chipping of the cutting edge in laser-machined tools is reduced by up to 3 times in comparison to ground or eroded tools, which extends the service life by up to 40 percent.
Laser drilling with the LASERTEC PowerDrill series
DMG MORI’s PowerDrill series is specifically designed for 5-axis laser drilling of turbine blades, combustion chambers,other components from the aviation, and stationary gas turbine sectors. It delivers powerful performance in laser processing of turbine components, with sizes up to XXL. Cooling air holes can be created using percussion, trepanning, or drilling on the fly (up to 500 holes/second with a rotating workpiece).
Depending on the application, the LASERTEC PowerDrill machines are available with 9 kW to 23 kW fiber lasers. The machine concepts are rounded off by state-of-the-art functions such as variable collimation, flash detection, capacitive distance sensors, and optional tool changers. These special PowerDrill software tools enable the convenient programming and processing of complex components.
