DT Series — Enclosed 2-in-1 laser machines (sheet + tube)

The DT Series has three models. The 4020DT12 cuts 4,000×2,000 mm sheet and Ø8–120 mm tube, the 6025DT26 reaches 6,000×2,500 mm and Ø15–250 mm, and the 12025DT28 12,000×2,500 mm and Ø15–280 mm. The tube length is the same as the table length: 4,000, 6,000 and 12,000 mm. All three work with 1–60 kW sources and an acceleration of up to 1.5 G.

It means the DT Series cuts both sheet and tube on the same machine, without a second machine. The difference shows in the investment, in the floor space and in the number of people needed to keep it running. It processes the same materials as sheet and as tube: mild steel, stainless steel, aluminium alloys, brass and copper.

The DT Series has an ACME chuck with eight cylinders, which clamps twice as hard as a standard one. Its bore is square, so the tube passes through without being guided. For the chuck, the manufacturer gives a range of Ø8–250 mm, while its specifications table goes up to Ø280 mm on the 12025DT28. On the small model, the 4020DT12, tube ranges from Ø8 to Ø120 mm.

On the DT Series, the table change takes 15 seconds: in that time, the full table moves out and the prepared one moves in under the head. This is where the efficiency gain of more than 30% quoted by the manufacturer comes from. The table load depends on the model: up to 1.6 t on the 4020DT12, 4.8 t on the 6025DT26 and 16 t on the 12025DT28.

The DT Series works at 115 m/min with an acceleration of up to 1.5 G, the same on all three models. The gantry crossbeams, made of aerospace-grade extruded aluminium, are light, so the gantry starts and stops faster, and the two servo motors that drive it move the head quickly from one contour to the next.

The DT Series has a full protective enclosure that surrounds the machine on all sides. All three models have it, together with the automatic nozzle changer and closed-loop air pressure control: the machine automatically fits the right nozzle for the sheet, and the pressure is measured and corrected on the fly.

Both cut sheet and tube on the same machine, with 1–60 kW sources. The ST Series is the compact version: sheet up to 6,000×2,500 mm, tube up to Ø250 mm and a table load of up to 1.8 t. The DT Series goes up to 12,000×2,500 mm, tube up to Ø280 mm and 16 t on the table, and also has a table change in 15 seconds.

The DT Series footprint increases with the size of the working area. The 4020DT12 is 11,100 mm long, 4,700 mm wide and 2,600 mm high. The 6025DT26 measures 15,500×5,700 mm, at a height of 3,100 mm, and the 12025DT28 measures 31,000×5,700 mm, also 3,100 mm high. On the two larger models, width and height are the same; only the length differs.
