DMG MORI to demonstrate Additive Manufacturing of PCD tools at GrindingHub
DMG MORI, headquartered in Tokyo, Japan, will showcase the use of Additive Manufacturing to produce cutting tools at this year’s GrindingHub exhibition, taking place in Stuttgart, Germany, from May 5–8, 2026. The company will demonstrate the advantages over conventional manufacturing, presenting a complete process chain that includes its LASERTEC 12 SLM and LASERTEC 20 PrecisionTool. DMG MORI will also be showcasing a second-generation Vertical Mate 85 for conventional grinding.
The company will use its LASERTEC 12 SLM Laser Beam Powder Bed Fusion (PBF-LB) Additive Manufacturing machine to build a milling head from polycrystalline diamond (PCD). The LASERTEC 20 PrecisionTool laser machine will then be used to finish the cutting edge.
Both the LASERTEC 12 SLM and the larger LASERTEC 30 SLM 3rd Generation are intended to serve as solutions for the Additive Manufacturing of milling heads. The advantage over conventional manufacturing processes reportedly lies in the complex geometries that the additive process can achieve. For example, internal cooling channels can be integrated to ensure optimal heat dissipation during machining with ultra-hard cutting materials.
DMG MORI’s LASERTEC 20 PrecisionTool offers advanced finishing of cutting edges. The five-axis laser machine rounds cutting edges in a single clamping without post-processing at a speed of up to 5 mm/min with 1.6 mm thick PCD. The machine can also measure the stroke profile of the round laser chamfer and adjust it directly on the machine. The LASERTEC 20 PrecisionTool produces cutting edges with a sharpness of less than 1 µm and a defined cutting edge rounding of 3 µm, 6 µm, 9 µm, and 15 µm. Negative chamfers are also possible. In addition, the process-reliable laser processing contributes to higher cost-effectiveness, increasing tool service life by up to a factor of 2.5, states the company.
