Our best estimate for a swiss-type lathe in this class — not a quote from Star Micronics. Configuration moves it a long way.

Overview

The Star SL-10 is a Swiss-type lathe for bar up to 10 mm (25/64 in), weighing 1,600 kg on a footprint of 1,865 × 795 × 1,815 mm. For so small a bar size it carries a strong main spindle motor, 3.7 kW continuous and 5.5 kW on the 10min./25%ED rating, and its table spells out small-part limits that most tables leave unstated.

Headstock stroke depends on the guide bush fitted. With the stationary guide bush it is 135 mm (5-5/16 in). The RGB arrangement is listed at 105 mm and the RMGB arrangement at 75 mm. Settle which of these your parts need before ordering, because the stroke sets the longest feature that can be turned without re-gripping the bar.

Tooling comes in separate groups: 6 main turning tools on 8 mm or 10 mm shanks, a 6-spindle back unit holding 6 tools, and a cross drilling unit with 1 tool in an ER11 collet plus 4 cartridge positions. Capacity limits are stated outright. Drilling goes to 6mm (15/64in) and tapping to M5xP0.8. Finished parts up to 70mm (2-3/4in) long can be ejected from the front, and the maximum parts projection length is 20mm (25/32in).

The sub spindle is listed at 9,000 rpm with 0.55 kW continuous and 1.1 kW on the 15min./40%ED rating. Rapid traverse is 35 m/min on X1, X2, Y1, Z1 and Z2 and 15 m/min on Y2. The control is a FANUC 32i-B with a 10.4" color LCD. The SR-10J, also a Ø10 mm(25/64 in) machine, is listed lighter at 1,400 kg with a 2.2 kW continuous main spindle.

Strengths & Limitations

Strengths

Main spindle motor of 3.7 kW continuous and 5.5 kW (10min./25%ED) on a 10 mm (25/64 in) bar machine, against 2.2 kW continuous on the SR-10J
Three guide bush arrangements, with headstock strokes of 135 mm (5-5/16 in), 105 mm and 75 mm
6-spindle back unit holding 6 tools for back-end work
Cross drilling unit with 1 tool (ER11) and 4 cartridge positions
Y2 axis listed with its own 15 m/min rapid rate, alongside 35 m/min on X1, X2, Y1, Z1 and Z2
Narrow footprint of 1,865 × 795 × 1,815 mm

Limitations

Bar and chucking diameter end at 10 mm (25/64 in)
Drilling is limited to 6mm (15/64in) and tapping to M5xP0.8
Headstock stroke drops from 135 mm (5-5/16 in) to 105 mm with RGB and to 75 mm with RMGB
Sub spindle power is 0.55 kW continuous, far below the 3.7 kW of the main spindle
Front ejection takes parts up to 70mm (2-3/4in) long only

Best For

Small-diameter parts from bar up to 10 mm (25/64 in) Tough materials at small diameters, where 3.7 kW of continuous spindle power helps Parts with cross holes and back-end features that need the 6-spindle back unit Small threaded parts within the M5xP0.8 tapping limit Tight floor plans: the machine is 795 mm on its short side

Frequently Asked Questions

01 What is the headstock stroke of the Star SL-10?

It depends on the guide bush. The table gives 135 mm (5-5/16 in) with the stationary guide bush, 105 mm for RGB and 75 mm for RMGB. Choose the arrangement from the longest turned length on your parts, since a shorter stroke means re-gripping the bar part-way through longer pieces.

02 How many tools does the SL-10 carry?

There are 6 main turning tools on 8 mm or 10 mm shanks, a 6-spindle back unit with 6 tools, and a cross drilling unit with 1 tool (ER11) plus 4 cartridge positions. What goes into the cartridge positions is not detailed in the table, so ask which cartridges are included.

03 What are the drilling and tapping limits?

Maximum drilling capability is 6mm (15/64in) and maximum tapping capability is M5xP0.8. Both are generous relative to a 10 mm (25/64 in) bar, but they are hard limits, so parts with larger bores need boring passes instead of a single drill.

04 How long a part can be unloaded?

The maximum length for front ejection is 70mm (2-3/4in), and the maximum parts projection length is 20mm (25/32in). Parts longer than the front ejection limit need a different unloading method, which should be discussed before the machine is specified.

05 How does the SL-10 differ from the SR-10J?

Both take Ø10 mm(25/64 in) bar and use a FANUC 32i-B control. The SR-10J is listed at 1,400 kg with a main spindle of 2.2 kW(continuous)/3.7 kW(15min./60%ED). The SL-10 weighs 1,600 kg and its main spindle is rated 3.7 kW continuous and 5.5 kW (10min./25%ED), so it has more power for the same bar size.
