FEATURE Metal Products To CNC or not to CNC?


In industry, both 3D printing and CNC machining allow manufacturers to rapidly produce complex, strong and lightweight parts but sometimes it can be difficult to know which technology will better suit an application. Here, Jonathan Wilkins, marketing director at obsolete industrial parts supplier, EU Automation, discusses the applications for CNC machining and additive manufacturing.

produced on a Renishaw multi-laser high productivity RenAM 500Q metal additive manufacturing (AM) system. Initial production will be at Renishaw’s Additive Manufacturing Solutions Centre located in Staffordshire, UK, followed by a transition towards in-house manufacture by Atherton Bikes. Also partnering in the project is Dave Weagle,

lobal engineering company, Renishaw is working with new mountain bike brand,


Atherton Bikes, to produce additively manufactured titanium lugs for the company’s bike frames. The new brand was launched in January by the Atherton siblings: Gee, Rachel and Dan, and co-founded by Piers Linney of Dragons’ Den fame. The introductory bike range will be

the renowned suspension designer, along with Ed Haythornthwaite and other members of the former Robot Bike Company. Renishaw had previously worked with the Robot Bike Company by manufacturing the titanium lugs for its R160 bike frame. The lugs for Atherton Bikes are the first bike


components to be built on the four-laser RenAM 500Q system, which enables increased productivity, without compromising on quality. “Renishaw is a world-leader in metal additive


manufacturing machines,” explains Jono Munday, additive manufacturing applications manager at Renishaw. “Due to our position as a leading metrology business, we are also perfectly


positioned to help customers develop an end-to- end solution, from AM build, all the way through machining and post-processing, providing an end-use engineered component. “Manufacturing the lugs on the RenAM 500Q


enables rapid production time,” adds Munday. “This means that the bike frame development can be turned around quickly and customised to the exact requirements of the rider, whether that is the Atherton Racing team on the World Cup circuit or an individual retail customer. Whereas traditionally a lot of tooling is required, additive manufacturing is an entirely digital process, meaning that the lugs can be modified in CAD and reproduced more efficiently.” During the development of the new Atherton


Bikes, Renishaw has been giving feedback and modifying the lugs so that they can be built accurately and successfully. The AM build process, machining and post processing are managed by Renishaw at its Solutions Centre.
