Additive Technology Mated with Subtractive Machines DMG MORI (Hoffman Estates, IL) has introduced the second in its line of hybrid additive/subtractive machines that integrates 3D printing technology onto its CNC machine platforms. A pro- totype of the Lasertec 4300 3D, which is based on the turn-mill NT4300SZ platform, will be debuted at IMTS. Production of the Lasertec 4300 3D begins later this year, with shipment expected in 2015. This marks the second of the company’s CNC machine platforms with 3D printing technology with more to follow. The Lasertec 65, which debuted in late 2013 and begins shipping later this year, was the first hybrid additive/subtrac- tive DMG MORI machine. The machine platform chosen was the DMU 65 monoBLOCK five-axis machining center. The hybrid machines use a metal deposition process in which a powder nozzle sprays metallic powder into the laser
beam, melting the powder in layers into the base material. DMG MORI said the process is up to 20 times faster than laser sintering in a powder bed. Most common metal powders can be processed, including steel, nickel and cobalt alloys, and brass.
The spray process builds up successive layers of differ- ent materials with wall thicknesses of 0.5–5 mm possible, depending on the laser and the nozzle geometry. Complex 3D contours can also be generated in layers without supports. The individual layers can then be accurately machined before the areas become inaccessible to a cutter or other tools due to deposited material interference.
Universal Five-Axis Machining Centers Built on Automotive Platform
GROB Systems Inc. (Bluffton, OH) has expanded its five-axis universal machining center line with the introduction of the G750 with a work envelope of 1280 diameter × 1005
