New 5-axis capacity online: DMG MORI DMU 80 monoBLOCK installed.

Byadmin

Our second DMG MORI 5-axis machining center — a DMU 80 monoBLOCK — came online for production work in November. This roughly doubles our 5-axis capacity for large aluminum battery enclosure work and unlocks a few specific things we could not do well before.

What it adds

The DMU 80 has a working envelope of 800 mm × 800 mm × 600 mm — roughly 31 × 31 × 24 inches. Combined with our existing DMU 65 and the two Mazak VTC-300A units, we now have 5-axis capacity to about 80 × 40 × 24 inches across multiple machines, which means we can run two or three different battery enclosure programs in parallel without bottlenecking.

The DMU 80 also has a heavier table (3,500 kg capacity) and a more rigid spindle — better for the larger truck-program enclosures we have been quoting. Our DMU 65 is a great machine but the truck work was at the edge of its rigidity envelope.

Why we chose this machine specifically

We evaluated four candidates: the DMU 80, a Mazak Variaxis i-700, a Hermle C 32, and a Heller F 6000. Each has strengths. We picked the DMU 80 for two reasons.

First: tool consistency with our existing DMG MORI machine. Operators can move between the DMU 65 and the DMU 80 without retraining, and our CAM postprocessors and tool libraries carry over directly. This is not a small thing — it shaves probably four months off the practical ramp time to full production.

Second: the DMG MORI service-and-support contract is the deepest in the Southeast. Mazak and Hermle both have great machines but their nearest 24-hour service tech for our model lines is a longer drive. For a customer with a tight delivery schedule, that difference matters when something goes wrong at 2 AM.

What is now possible that was not before

We can now quote work in two specific lanes that were marginal for us before:

  • Class-8 truck-spec enclosures up to 78 inches, where the rigidity matters more than the absolute envelope size.
  • Higher-volume passenger-EV runs above 15,000 units per program, where we previously would have had to run weekend shifts on a single machine to keep pace.

If you are looking at one of these lanes for an upcoming program, send us a print.
