IMTS 2016: New “Hybrid” Additive/Subtractive Machining System


The Vertex 55X-H “hybrid” technology will be demonstrated in Mitsui Seiki’s IMTS 2016.

The basic concept of Mitsui Seiki’s new Vertex 55X-H combines a precision-built traditional CNC vertical machining center with a spindle-adapted laser DED (Direct Energy Deposition) / powder feed nozzle.

Parts can be 3D printed from nothing or material can be added to existing parts. The nozzle loads into the tool changer like any conventional tool and is changed automatically via the CNC program prompts, a milling/drilling tool replaces it and aspects of the workpiece can be machined conventionally – including internal features. For example, perhaps surface work needs to be machined before the next layer of material is added. Or, the workpiece can be printed to completion and then subsequent machining operations can be accomplished.  

Customers can choose either a CAT or HSK spindle that offers 15,000 to 30,000 rpm. Further, Mitsui Seiki has integrated a coolant system for either dry or wet machining best practices. The working range is from 550mm to 750mm in X-axis; 600mm to 800mm in Y-axis; and 400mm to 750mm in Z-axis. Ultimately, most all of the company’s machines will be able to be equipped with the new hybrid technology, including its large trunnion-style machining centers.

The applications ideally suited to Mitsui Seiki’s particular hybrid machining solution include the repair of a number of different types of airfoil parts, such as high-pressure turbine and compressor blades, low pressure blades, blisks/IBRs and impellers for the aerospace, power generation, and oil and gas industries. Further, as large truck and off-road equipment OEMs use more super hard materials in the production of parts and diesel engines, hybrid technology is ideal for repair operations in those industries as well. General part recovery is another area where hybrid machinery could be used to great advantage in traditional machining environments where a scrapped part can cost a company up to hundreds of thousands of dollars.
