Space-Saving Five-Axis Machine Cuts Large Parts
IMTS 2018: DMG MORI’s two XXL machines, the DMU 200 gantry and DMU 340 gantry, are designed for large-part applications.
DMG MORI’s two XXL machines, the DMU 200 gantry and DMU 340 gantry, are designed for large-part applications. Both models offer five-axis simultaneous machining and combine a large work area with a small footprint, according to the company.
The DMU 200 is suitable for the aerospace, automotive, mold making and energy industries. Its spindle rotates as fast as 30,000 rpm. With optional Ultrasonic or Lasertec technology, the gantry can machine aluminum, composite or welded components as heavy as 22,046 lbs.
Featuring a top gantry design, the DMU 340 produces parts for the aerospace, mechanical engineering, and tool and mold manufacturing industries. Its work area measures 134" × 110" × 49". Expansion options ranging to 236" in the X axis and 59" in the Z axis are available.
While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.
Cryogenic machining achieves dramatic tool life gains not by flooding the cut, but by refrigerating the tool.
The recipe for best results is simple: Start with a rigid machine, add a high pressure through-the-spindle coolant system, then combine these with the right drill geometry plus the right speeds and feeds.
