For generations, precision gear manufacturers have faced a difficult compromise: use highly specialised, dedicated machines, accept long lead times and costly tooling, or limit design ambition to what conventional equipment can achieve. Dontyne Gears is challenging that model.
Working with NCMT and using an Okuma GENOS M460V-5AX machining centre, Dontyne has demonstrated that complex, high-accuracy gear forms can be produced on a standard 5-axis platform, supported by intelligent software that links gear design, cutting strategy, code generation and inspection in one digital workflow.
The breakthrough centres on Dontyne’s Gear Production Suite, which can create a virtual twin of a gear or gear pair, validate contact conditions, simulate machining and generate G-code in seconds. With the GENOS M460V-5AX providing the rigidity, thermal stability and accuracy required, Dontyne can manufacture demanding geometries using readily available end mill tooling, rather than expensive, bespoke cutters. The machine has also been equipped with a Renishaw SPRINT probing system, allowing cylindrical gears to be inspected on the machine and supporting a closed-loop approach that reduces set-up time and improves confidence in the final part.
The results are significant. Dontyne has shown that spiral bevels, hypoids, helicals, internal gears and special-profile forms can be produced flexibly on one adaptable machine, often achieving ISO 4-5 results on the first attempt after extensive testing and software development. What traditionally might require multiple dedicated machines and months of preparation can now be approached in days, opening new possibilities for manufacturers working in aerospace, automotive, energy and other high-value sectors.
The project has also gained important industry recognition. The British Gear Association has supported further investigation into the method, helping to validate the approach and build credibility around 5-axis CNC gear production as a practical alternative to established processes. Its involvement has been important, because independent technical scrutiny helps manufacturers understand where this method can be applied and how it can overcome long-standing limitations in conventional gear making.
For NCMT, the partnership underlines what can be achieved when advanced machine tools, application knowledge and forward-thinking software development come together. For Dontyne, it has created a powerful demonstration platform for customers and a route to more flexible, cost-effective gear manufacture across demanding production environments and specialist applications.
