Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

The DN Solutions SMX 2100 L is the long-bed SMX 2100: maximum turning length is 1,540 mm, where the standard SMX 2100 stops at 1,040 mm (41 in). The 8 in chuck, the 600 mm maximum turning diameter and the 5,000 rpm spindle with 22 kW (30 hp) and 467 N·m (344 ft-lb) carry over.

Bed length on a mill-turn is bought for shafts, rolls, screws and long housings that would otherwise travel from a long lathe to a long-travel machining center. Two cautions follow from the figures. First, the spindle is the one from the short machine, so the extra length does not come with extra torque for the heavier blanks that long parts often are. Second, the table has no rows for a tailstock, a steady rest or a second spindle on this model, and a slender part of this length needs support somewhere along it. Ask which work-support options exist before assuming the full length is usable on thin shafts.

Installation changes mainly in one direction. The machine is 5,630 mm (221 in) long, 2,770 mm (109 in) wide and 2,777 mm (109 in) high. Weight is 16,200 kg (35,715 lb), about 9% more than the 14,900 kg (32,849 lb) of the SMX 2100.

For long parts that are also large in diameter or heavy, the SMX 2600 covers the same 1,540 mm (61 in) of turning length with a 10 in chuck, 660 mm (26 in) of turning diameter, 30 kW (40 hp) and 724 N·m (534 ft-lb) at 4,000 rpm. The SMX 2100 L is the better match when the parts are long but slim and the 5,000 rpm spindle is useful.

DN Solutions lists cooling of the spindle and feed axes with thermal compensation for the series. That is relevant here, because long parts mean long cycles and length is where thermal growth shows first.

Strengths & Limitations

Strengths

1,540 mm of turning length, against 1,040 mm (41 in) on the SMX 2100
Keeps the 5,000 rpm, 467 N·m (344 ft-lb) spindle and 8 in chuck of the short-bed model
600 mm of turning diameter gives a milling head clearance along the whole length of the part
Spindle and feed-axis cooling with thermal compensation is listed for the series, which suits long cycles on long parts
Width and height stay at 2,770 mm (109 in) and 2,777 mm (109 in); only the length grows

Limitations

Machine length is 5,630 mm (221 in) and weight 16,200 kg (35,715 lb)
22 kW (30 hp) and 467 N·m (344 ft-lb) on an 8 in chuck; the SMX 2600 has 30 kW (40 hp) and 724 N·m (534 ft-lb) for the same 1,540 mm (61 in) of turning length
The table has no second-spindle rows for this model, so the far end of a shaft needs a second setup
No tailstock, steady-rest, milling-spindle or magazine figures appear in the table

Best For

Slim shafts, screws and rolls up to 1,540 mm long Long parts with milled flats, keyways and cross holes along their length Long workpieces small enough in diameter to benefit from 5,000 rpm Long-cycle parts where thermal compensation of spindle and feed axes helps hold size

Frequently Asked Questions

01 How much longer is the SMX 2100 L than the SMX 2100?

The SMX 2100 L has a maximum turning length of 1,540 mm. The SMX 2100 has 1,040 mm (41 in). Maximum turning diameter is 600 mm on both, and both have an 8 in chuck with a 5,000 rpm, 467 N·m (344 ft-lb) spindle.

02 Does the SMX 2100 L have a second spindle or a tailstock?

The table for this model has rows for one spindle only: 5,000 rpm, 22 kW (30 hp) and 467 N·m (344 ft-lb). It lists neither a second spindle nor a tailstock or steady rest. Since a 1,540 mm part usually needs support, ask DN Solutions what work-support equipment is available for the L.

03 What are the dimensions and weight of the SMX 2100 L?

Length, width and height are 5,630 × 2,770 × 2,777 mm (221 × 109 × 109 in). The machine weighs 16,200 kg (35,715 lb). The length is the figure to check first against the bay, since a long-bed machine also needs room at the ends for loading long stock.

04 Should I choose the SMX 2100 L or the SMX 2600?

Both turn 1,540 mm. The SMX 2100 L has an 8 in chuck, 5,000 rpm and 467 N·m (344 ft-lb). The SMX 2600 has a 10 in chuck, 4,000 rpm, 30 kW (40 hp) and 724 N·m (534 ft-lb), with 660 mm (26 in) of turning diameter. Slim, faster-running parts suit the L; heavier or larger-diameter parts suit the SMX 2600.
