Technology & Products
Key Products
Precision cutting tools (drilling tools, milling cutters, threading tools, reamers, clamping systems, grooving systems, PCD-/PCBN-Tools). Also, DIANOZ diamond-tipped 3D printer nozzles.
Technological Advantage
(1) CLAIMED: DIANOZ diamond nozzles enable 'limitless printing' with 50 kg+ carbon material without nozzle degradation. (2) VERIFIED: Customer AIM3D confirmed 3+ years of continuous operation printing carbide without nozzle replacement, solving a critical production bottleneck where standard nozzles failed quickly with abrasive materials. The advantage is DEFENSIBLE based on Gühring's 40+ years of PCD manufacturing know-how and proprietary diamond bonding processes developed for precision cutting tools across automotive and aerospace applications.
Differentiation
Value Proposition
Eliminates recurring nozzle replacement costs for abrasive-material 3D printing: standard brass or hardened steel nozzles degrade within days to weeks when printing carbon fiber or ceramic-filled filaments, requiring frequent $50-200 replacements and causing production downtime. DIANOZ PCD diamond nozzles have demonstrated 3+ years of continuous printing without measurable wear at customer AIM3D, reducing consumable costs by over 90% and eliminating nozzle-swap production interruptions entirely.
How They Differentiate
Gühring differentiates itself through a comprehensive product portfolio, in-house carbide production, machinery and plant engineering, and a "one-stop-service" approach for precision cutting tools. Additionally, their DIANOZ polycrystalline diamond (PCD) nozzles offer superior wear resistance for 3D printing abrasive materials.
