OGM TO UNVEIL NEW HYBRID ADDITIVE MANUFACTURING BUREAU SERVICE ON LUMEX STAND AT MACH21-Feb-2018 LUMEX
OGM has already successfully used this new technology to manufacture conformal cooling channels and injection moulding inserts with cycle time reduction and improved part quality, but also plans to offer sophisticated end use parts, delivering to companies a route to create components that currently have no conventional means of production.
“We are the first company in the UK to offer this new bureau service based on metal HYBRID additive manufacturing,” says Marcel Gowers, who recently joined OGM from the aerospace and defence sector to lead the bureau service. “We’re excited to inform MACH visitors about the service and explain how it can enhance their part quality and dramatically reduce lead times”.
While Direct Metal Laser Sintered parts can be made quickly, they exhibit a rough surface finish which then requires post-processing, such as CNC machining to obtain flat surfaces and holes etc. Using OGM’s new bureau service, customers have the option of having a fully CNC finished part, or they can select specific features, geometry or surfaces that they wish to have machined.
As well as improving exterior surface quality, it also ensures that internal features – such as holes, tubes or flow channels – are smooth, making it ideal for applications that require fluid flow, such as injection mould tool insert cooling channels or nozzles for the food, aerospace and automotive industry.
For complex injection moulding tooling inserts, it can eliminate the costly, time-consuming process of Electro Discharge Machining (EDM), further helping to bring down production costs and drastically reducing lead times.
OGM is a specialist in manufacturing injection moulded parts, so offering an AM bureau service is a new departure for the company.
The machine that creates the parts has a build volume of 250 x 250 x 300mm, making it large enough to make medium-sized mould tools or volumetric part production. It was originally bought to produce mould tool inserts – but will now also be used to make a host of end-use production parts.
In 2017, there have been further enhancements and upgrades to the LUMEX Avance-25. The latest specifications produce a maximum build speed of 14 cc/h with 500 W laser; 35 cc/h with 1 KW laser. Worksize of W256mm x D256mm x H185mm, with an option to increase to W256mm x D256mm x H300mm.
Imagine the ability to "grow" a metal component in layers with complex internal features and then fine mill those internal features as the layers are added to give a perfect surface finish, eventually encapsulating the intricate internal features and their machined surface finish inside the finished component. This is what makes the LUMEX such a unique and remarkable production machine tool, offering designers and manufacturers a route to designing what they can imagine, and not be limited by the restrictions of their current production methods, strategies and machines.
To meet the demands for large-size parts and high-speed operation, 2016 saw the launch of an addition to the series; the LUMEX Avance-60 possessing a maximum work size of W600mm × D600mm × H500mm, a 1000W Yb Fiber Laser and the 45,000RPM Matsuura Maxia CNC milling Spindle installed.
