Overview

Spindle power is the figure that places the Star NEW SD-26 Type S. Its main spindle is rated 5.5 kW continuous and 7.5 kW at 10min./25%ED, on a machine for 26 mm (1.02 in) bar, and it holds 10,000 rpm on both the main and the sub spindle. The NEW SP-20, one size down, is listed at 2.2 kW (CONT.)/3.7 kW (15min/60% ED).

That power comes in a frame of 3,600 kg with a footprint of 2,550 × 1,300 × 1,995 mm. The SR-32J, the next size up at ø32mm (1-1/4in), weighs 4,100 kg and has a 7.5 kW (continuous) / 11.0 kW (10min./25%ED) spindle but tops out at 8,000 rpm. The SD-26 therefore keeps the speed of the small machines while carrying most of the motor of the larger one, which suits tough materials at diameters where the SR-32J's 8,000 rpm would leave surface speed short.

Headstock stroke is 260 mm (10-15/64 in), and that is also the maximum turning length per chucking. The sub spindle carries a substantial rating of its own, 3.7 kW continuous and 5.5 kW at 10min./40%ED, enough for turning and drilling on the back end and not only light finishing.

Turning tools are listed as 5 tools on the front + 2 tools on the rear. That is a short list for a machine with this much spindle, so the tool plan deserves attention on parts with many turned features. Up to 8 axes are listed, including Y-axis, C1 and C2, with a Y-axis stroke of ±15 mm, and rapids are 36 m/min on X1, Y1, Z1, X2 and Z2.

Strengths & Limitations

Strengths

Main spindle rated 5.5 kW continuous / 7.5 kW (10min./25%ED) at up to 10,000 rpm
Sub spindle rated 3.7 kW continuous / 5.5 kW (10min./40%ED), also at 10,000 rpm
260 mm (10-15/64 in) headstock stroke
36 m/min rapid traverse on X1, Y1, Z1, X2 and Z2
Y-axis with ±15 mm stroke and up to 8 axes including C1 and C2

Limitations

Turning tools are listed as 5 tools on the front + 2 tools on the rear
Bar capacity stops at Ø26 mm (1-1/64 in); the SR-32J takes ø32mm (1-1/4in)
Weighs 3,600 kg against 2,250 kg for the NEW SP-20, so check floor loading and access
Y-axis stroke is ±15 mm, which bounds how far off centre a feature can be milled

Best For

Stainless and other tough bar up to 26 mm (1.02 in) that needs spindle power Parts up to 260 mm (10-15/64 in) long in one chucking Heavier back-end work on the 3.7 kW continuous sub spindle Small turned diameters that benefit from 10,000 rpm

Frequently Asked Questions

01 How much spindle power does the NEW SD-26 Type S have?

The main spindle is listed at 5.5 kW continuous and 7.5 kW at 10min./25%ED. The sub spindle is listed at 3.7 kW continuous and 5.5 kW at 10min./40%ED. Both spindles run to 10,000 rpm.

02 What is the maximum part length on the NEW SD-26 Type S?

Maximum turning length is 260mm (10-15/64 inch), which matches the 260 mm (10-15/64 in) headstock stroke. Maximum turning diameter is φ26mm (1-1/64 inch). Longer parts would need re-chucking, which the table does not cover.

03 How does the NEW SD-26 Type S compare with the NEW SP-20?

The NEW SP-20 is the smaller machine: ø20mm bar with ø25.4mm (1in) as an option, 2.2 kW (CONT.)/3.7 kW (15min/60% ED) on the main spindle, 35 m/min rapids and 2,250 kg. The NEW SD-26 Type S takes Ø26 mm (1-1/64 in) bar as standard, has a 5.5 kW continuous / 7.5 kW main spindle, 36 m/min rapids and weighs 3,600 kg. The NEW SP-20 gang post is listed with 8 tools (12mm) or 7 tools; the SD-26 has 5 tools on the front + 2 tools on the rear.

04 How many turning tools does the NEW SD-26 Type S carry?

The table lists 5 tools on the front + 2 tools on the rear. Parts with many separate turned features should be laid out against that count early, since the table gives no larger arrangement.

05 What floor space and weight should be planned for?

The footprint is 2,550 × 1,300 × 1,995 mm and the machine weighs 3,600 kg. Allow for the bar feeder and chip handling separately; the table covers the machine only.
