Price estimate

Uncertain

We do not have a price for the DMG Mori SL-403 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The DMG MORI SL-403 is a large turning center for shaft work, built in two bed lengths. Type 800 has 995 mm (39.2 in) of Z travel and takes workpieces up to 958 mm (37.7 in) long; Type 2000 has 2,000 mm (78.7 in) of Z travel and takes 2,158 mm (85 in). X travel is 345 mm (13.6 in), maximum workpiece diameter 650 mm (25.6 in) and bar capacity 185 mm (7.3 in).

DMG MORI also splits the model into versions by letter. Maximum turning diameter is given as 24.4 in for the B and C versions and 25.5 in for the BMC and CMC versions. An oil chiller is standard equipment on the C-type. The letters matter when comparing quotations, because the diameter limit and the chiller both depend on them.

Shaft work depends on the tailstock, and its travel is 33.5 in on the 800 type and 78.7 in on the 2,000 type. Rapid traverse is 787.4 ipm in X and 944.9 ipm in Z, and the turret indexes in 0.4 sec for one station.

The spindle is driven by an AC motor that DMG MORI describes as high-output and high-torque, intended for heavy and continuous cutting, but no power, torque or speed figure is published with it. Bed and legs are a single body, for resistance to twisting and bending.

The table lists X and Z travel only. The NLX 4000, by comparison, has 365 mm (14.4 in) of X and 120 mm (4.7 in) of Y, with 875 mm (34.4 in) or 1,685 mm (66.3 in) of Z depending on type.

Shafts up to 2,158 mm (85 in) long on Type 2000 Shorter heavy parts up to 958 mm (37.7 in) long on Type 800 Large-bore work with bar up to 185 mm (7.3 in) Flanges and discs up to 650 mm (25.6 in) in diameter

Frequently Asked Questions

01 What is the difference between the SL-403 Type 800 and Type 2000?

Bed length. Type 800 has 995 mm (39.2 in) of Z travel and a maximum workpiece length of 958 mm (37.7 in). Type 2000 has 2,000 mm (78.7 in) of Z travel and a maximum workpiece length of 2,158 mm (85 in). Tailstock travel is 33.5 in on the 800 type and 78.7 in on the 2,000 type. X travel is 345 mm (13.6 in) on both.

02 What is the maximum turning diameter of the SL-403?

It depends on the version. DMG MORI gives 24.4 in for the B and C versions and 25.5 in for the BMC and CMC versions. The technical data table lists a maximum workpiece diameter of 650 mm (25.6 in) for the model.

03 How fast are the axes and turret on the SL-403?

Rapid traverse is 787.4 ipm on the X-axis and 944.9 ipm on the Z-axis. Turret indexing time is 0.4 sec for one station. On a long shaft with few tool changes the Z rapid matters most, since the turret travels the length of the part between cuts.

04 Does the SL-403 have a Y-axis?

DMG MORI's table for the SL-403 lists X travel of 345 mm (13.6 in) and Z travel only. No Y travel is given. If off-centre milling is needed, the NLX 4000 is listed with 120 mm (4.7 in) of Y travel.

05 Is an oil chiller included on the SL-403?

DMG MORI states that an oil chiller is included as standard equipment on the C-type. Nothing is stated for the other versions, so check the quotation if the machine being considered is not a C-type.
