DN Solutions SMX 2100 L

The DN Solutions SMX 2100 L is the long-bed variant of the SMX 2100 platform, stretching the Z-axis to accommodate parts up to 1,540 mm (60.6 in) in turning length. It's built for shops that need B-axis mill-turn capability on longer shafts, drive components, and cylindrical workpieces that won't fit in the standard SMX 2100's 1,040 mm envelope.

The main spindle runs an 8-inch chuck at 5,000 RPM with 22 kW (29.5 hp) and 467 Nm (344 ft-lbs) of torque. That's plenty for steel and stainless work on medium-diameter parts. The B-axis milling spindle delivers 12,000 RPM for cross-drilling, angular milling, and contouring operations without unclamping the workpiece. You get true done-in-one processing on parts that would otherwise bounce between a lathe and a machining center.

DN Solutions paired this machine with dual spindles — the right spindle matches the left at 5,000 RPM and 22 kW, so you can transfer parts for back-working without manual intervention. That's a significant productivity advantage for shaft-type parts that need features on both ends. The whole package weighs in at 16,200 kg (35,715 lb), giving it the thermal mass and rigidity you'd expect from a machine in this class.

At roughly 5,630 mm long, 2,770 mm wide, and 2,777 mm tall, it needs more floor space than the standard-bed SMX 2100 but stays more compact than stepping up to the SMX 2600 or 3100 series. The FANUC 31i-B5 control handles 5-axis simultaneous machining through CUFOS, and the machine accepts bar stock through the main spindle for automated production runs. For shops machining long automotive driveshafts, aerospace actuator bodies, or oil and gas components, the SMX 2100 L hits a sweet spot between capability and cost that's hard to match in the sub-$350K price range.
