• Wear-free, non-contact and precise machining of a wide range of materials, including metal, carbide, ceramic and diamond 
• Utmost machining precision with solid-based machines
• Unique application technology and operation for the implementation of turnkey applications

DMG MORI: varied laser technologies for different applications

The standard lasers used in DMG MORI CNC laser machines include fibre lasers (cw / qcw) and ultrashort pulse lasers, such as femtosecond lasers. Their short pulse frequency means the ultrashort pulse lasers offer 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 offer process-reliable and reproducible laser ablation of surfaces of different thickness, fine contours as well as delicate cavities for the production of injection moulds, press tools, inscriptions and other engravings with the utmost precision.

These machines are capable of effortlessly machining tool steel or even highly wear-resistant materials such as carbide or ceramics with appropriate laser beams (nanosecond or femtosecond lasers), 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 and 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 fibre 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 Special PowerDrill software tools enable the convenient programming and editing of complex components.
