ELB-Schliff’s New millGrind Device Melds 3D Printing & Grinding

NewHybrid AdditiveManufacturing GrindingA new generation of hybrid machine tools are combining additive manufacturing capabilities with milling and CNC turning functionality.

Now German machine tool maker ELB-Schliff has introduced a grinding machine they say is equipped for additive manufacturing tasks, and this hybrid version of the company’s “millGrind” device is aimed at aerospace engine part production.

The millGrind features both subtractive – via grinding and milling processes – and additive laser cladding to generate precise, complex, critical end-use components from aerospace alloys within a single production cycle.

A laser metal deposition system from Hybrid Manufacturing Technologies is integrated into the machine, and the companies say the millGrind represents the world’s first hybrid grinder system.

They say CNC grinding and metal additive manufacturing, both high-value processes typically performed with high-end machines, complement each other as processes.While design features produced additively often require surface finish improvement, grinding excels at exactly that sort of application.

“Grinding particularly excels in cost-effectiveness for processing materials that are difficult to machine, such as nickel-based superalloys,” says ELB-Schliff. “The millGrind runs conventional grinding abrasives with superabrasive capability, and has an XYZ resolution of 0.1 micron. If hybrid milling takes additive manufacturing to a new level of productivity, then hybrid grinding takes additive manufacturing to a new level of precision.”

The company recently demonstrated their hybrid grinder device during the Paris Air Show, and that machine featured the optional additive manufacturing head within an automatic tool changer. The millGrind is said to offer grinding, boring, milling, laser cladding and on-machine measurement as well, and the machine shown in Paris was fitted with the Hybrid Manufacturing Technologies Ambit laser melting head developed in the UK.

The HMT metal deposition AM process – similar to welding – uses powdered metal blown onto a substrate via an inert carrier gas which is then melted by a laser. Using either of two nozzles for deposition 1.6 mm or 3 mm wide at deposition rates of 10-15 grams minute, the makers say the process is well suited to scaling up in size and speed.

Unlike the most common metal printing technique which uses a powder-bed method, the HMT method more closely approximates traditional subtractive machining processes. The AM head, sold in Europe and the US, is an example of the AM-on-CNC business Hybrid Manufacturing Technologies uses to retrofit existing CNC machines, and as of May, they say the process has been used to retrofit 10 units.

Elb-Schliff Werkzeugmaschinen GmbH and aba Grinding Technologies GmbH now operate under the AUTANIA GRINDING TECHNOLOGIES umbrella.
