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 Micronics SB-16R Type G is a 16 mm (5/8 in) sliding-headstock lathe whose table goes into detail on driven tooling: a 4-spindle power-driven unit with ER 16 collets running to 6,000 RPM, and a 5-spindle unit with ER 11 collets running to 10,000 RPM. Both are rated 1.0 kW continuous.

The two units trade collet size for speed and count. ER 16 holds larger drills and end mills but stops at 6,000 RPM. ER 11 limits shank size, adds a fifth spindle and reaches 10,000 RPM, the better match for small cross holes and slots where the cutter is a millimetre or two across and surface speed is hard to come by. At 1.0 kW continuous either way, cross work means light milling and drilling.

For turning, the tool post takes 6 tools at □12 mm or 7 tools at □10 mm. A 4-spindle back unit carries 4 tools for the sub spindle side, and the sub spindle itself is listed at 9,000 rpm with 0.55 kW continuous and 1.1 kW at 15min./40%ED. The main spindle is rated 2.2 kW continuous and 3.7 kW at 10min./25%ED.

Headstock stroke is 205 mm (8 in) with the guide bush. Without it the stroke is bar diameter x 2.5, to a maximum of 50 mm. The machine weighs 1,700 kg, measures 2,070 mm × 1,177 mm × 1,760 mm, rapids at 35 m/min on X1, Y1, Z1, X2 and Z2, and runs a Fanuc 0i-TD control with an 8.4-inch color LCD.

Strengths & Limitations

Strengths

5-spindle power-driven unit with ER 11 collets, listed at a maximum of 10,000 RPM
4-spindle power-driven unit with ER 16 collets for larger tools, up to 6,000 RPM
205 mm (8 in) headstock stroke with the guide bush, or guide-bushless running up to a maximum of 50 mm
6 tools at □12 mm or 7 tools at □10 mm on the turning tool post, plus a 4-spindle back unit
35 m/min rapid traverse on X1, Y1, Z1, X2 and Z2

Limitations

Power-driven units are rated 1.0 kW continuous, so milling is limited to light cuts
Sub spindle power is 0.55 kW continuous and 1.1 kW at 15min./40%ED
The ER 16 power-driven unit is limited to 6,000 RPM
Bar capacity is Ø16 mm (5/8 in); the SB-20R Type G takes Ø20 mm (25/32 in) at the same 1,700 kg

Best For

Turned parts up to 16 mm (5/8 in) with small cross holes and slots Small-tool cross work at up to 10,000 RPM with ER 11 collets Long parts within the 205 mm (8 in) guide-bush stroke Short parts up to 50 mm run without the guide bush

Frequently Asked Questions

01 What driven tooling does the SB-16R Type G have?

The table lists two power-driven units. The 4-spindle unit uses ER 16 collets and runs to a maximum of 6,000 RPM. The 5-spindle unit uses ER 11 collets and runs to a maximum of 10,000 RPM. Each is rated 1.0 kW continuous. Confirm with the dealer which unit is fitted to the machine being quoted.

02 How long a part can the SB-16R Type G turn?

With the guide bush the maximum headstock stroke is 205 mm (8 in). Without the guide bush the stroke is bar diameter x 2.5, with a maximum of 50 mm. Maximum machining diameter is 16 mm (5/8 in) in both cases.

03 What spindle speeds does the table list for the SB-16R Type G?

The sub spindle is listed at 9,000 rpm. The main spindle row reads 6,000 rpm, the same figure as the ER 16 power-driven unit and lower than the sub spindle, so confirm the main spindle maximum with the dealer. Main spindle power is 2.2 kW continuous and 3.7 kW at 10min./25%ED.

04 How many turning tools does the SB-16R Type G hold?

The turning tool post holds 6 tools with □12 mm shanks or 7 tools with □10 mm shanks. The back unit is a 4-spindle type carrying 4 tools for work on the sub spindle side.

05 How does the SB-16R Type G differ from the SB-12R Type G?

Mainly in bar size. The SB-16R Type G takes Ø16 mm (5/8 in) and weighs 1,700 kg. The SB-12R Type G takes Ø13 mm (33/64 in) and weighs 1,750 kg. Both list 2.2 kW (Continuous) / 3.7 kW (10min./25%ED) of main spindle power, 35 m/min rapid traverse on X1, Y1, Z1, X2 and Z2, and a Fanuc 0i-TD control.
