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

Overview

Star's SR-32J is a Ø32 mm (1-1/4 in) Swiss-type lathe with 8 axes and 18 tool positions, built around an 8,000 rpm main spindle and a counter spindle of the same speed. The 18 positions break down as 4 live, 6 turning, 4 end and 4 back.

That split tells you what kind of part the machine suits. Six turning tools cover roughing, finishing, grooving, threading and cut-off with one position to spare. Four live positions is a modest count for cross drilling and milling, so a part with many different cross features will use them up quickly. The four end tools drill and bore from the front, and the four back tools work the cut-off side while the main spindle starts the next part.

The main spindle is rated 7.5 kW continuous and 11.0 kW (10min./25%ED). The counter spindle is listed at 3.7 kW (5 HP) continuous with a 5.5 kW (10min/40%ED) short-time rating. Total installed power is 20 kW, which is the figure to hand to the electrician.

Two length figures appear in the table. Maximum machining length is 320 mm (12.6 in), the same as the headstock stroke, while maximum turning length is 310 mm (12-13/64 in). Plan long parts around the shorter one. Bar capacity can be taken to Ø34 mm (1-11/32 in) as an option. Rapids are 35 m/min on X1, X2, Y1, Z1 and Z2, the control is a Fanuc 32i-B, and the machine weighs 4,100 kg on a 2,690 × 1,345 × 1,780 mm footprint.

Strengths & Limitations

Strengths

18 tool positions: 4 live, 6 turning, 4 end and 4 back
8 axes, with a Y axis on the first tool group (the rapid row names X1, X2, Y1, Z1 and Z2 at 35 m/min)
Counter spindle runs at 8,000 rpm, matching the main spindle, with 3.7 kW (5 HP) continuous
Optional Ø34 mm (1-11/32 in) bar capacity above the standard Ø32 mm (1-1/4 in)
Total installed power of 20 kW is stated, which makes the electrical supply easy to plan

Limitations

Only 4 live tool positions, which limits parts with many different milled or cross-drilled features
Maximum turning length is 310 mm (12-13/64 in), slightly short of the 320 mm (12-19/32 in) headstock stroke
The table gives no live tool speed, so small-cutter milling capability cannot be judged from it
The counter spindle's 3.7 kW (5 HP) continuous rating is about half the main spindle's 7.5 kW

Best For

Turned parts with a few cross holes or flats, within the 4 live positions Bar up to Ø32 mm (1-1/4 in), or Ø34 mm (1-11/32 in) with the option Long shafts up to 310 mm (12-13/64 in) turning length Back-end finishing with 4 back tools and an 8,000 rpm counter spindle

Frequently Asked Questions

01 How are the 18 tool positions on the SR-32J divided?

The table lists 18 positions: 4 live, 6 turning, 4 end and 4 back. The turning tool rows separately confirm 6 tools. With only 4 driven positions, check a part's cross-drilling and milling operations against that count before quoting it on this machine.

02 What is the difference between maximum machining length and maximum turning length?

The table lists both without explaining the difference. Maximum machining length is 320 mm (12.6 in), which equals the headstock stroke of 320 mm (12-19/32 in). Maximum turning length is 310 mm (12-13/64 in). For planning purposes the shorter figure is the safe one.

03 What electrical supply does the SR-32J need?

Total installed power is listed as 20 kW. The main spindle accounts for 7.5 kW continuous (11.0 kW at 10min./25%ED) and the sub-spindle for 3.7 kW continuous (5.5 kW at 10min/40%ED). Voltage and current are not in the table, so take them from the installation documents.

04 Can the SR-32J run bar larger than its nominal size?

Yes, as an option. Standard bar capacity is Ø32 mm (1-1/4 in) and the table lists Ø34 mm (1-11/32 in) as optional. Confirm that a particular machine has the larger capacity fitted before ordering stock for it.

05 Which control does the SR-32J use?

A Fanuc 32i-B, per the control row. The table lists 8 axes, and the rapid traverse row gives 35 m/min on X1, X2, Y1, Z1 and Z2. No control options or software packages are listed in the table.
