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 SR-10R is listed as a Swiss-type lathe with a guide bushing and up to 7 axes: X1, Z1, X2, Z2, Y1, C1 and C2. Its bar capacity row gives 10 mm (0.394 in). The back spindle and the live tools are both listed at 10,000 RPM, and the main spindle motor at 2.2 kW continuous and 3.7 kW on the 10 min/25% ED rating.

Read this table with care. Its rows do not agree with one another on turning diameter, machining length, main spindle speed, tool count and electrical supply, so have Star confirm those figures before comparing the SR-10R with another machine.

The rows that stand on their own describe the layout. There is one Y axis, Y1, with a stroke of ±8 mm, and a C axis on each spindle. That is enough for cross holes, small flats and indexed features near the centreline of a small bar, with back-end work positioned by C2 alone. Rapid traverse is 30 m/min. The control depends on the type: Fanuc 31i-B on Type A and Fanuc 31i-B5 on Type B.

For installation, Star lists a machine weight of 2,600 kg, a floor space of 2,334 x 1,200 x 1,700 mm and a coolant capacity of 170 L.

Strengths & Limitations

Strengths

Back spindle and live tools both listed at 10,000 RPM
Y1 axis with ±8 mm of stroke, plus C1 and C2 for indexed work on both spindles
Works through a guide bushing, which supports slender parts at the cut
170 L coolant capacity on a 2,600 kg machine
Control is Fanuc 31i-B on Type A and Fanuc 31i-B5 on Type B

Limitations

Y-axis stroke is ±8 mm, and the axis list has a single Y axis
Rapid traverse of 30 m/min is below the 35 m/min listed for the SR-10J
Main spindle power is 2.2 kW continuous, with 3.7 kW available only on the 10 min/25% ED rating
Several rows of the table conflict, so diameter, length and tool count need confirming with Star before a job is planned

Best For

Small guide-bushing work with cross holes and flats near the centreline Parts needing live tools at up to 10,000 RPM Back-end features that can be positioned with the C2 axis Buyers prepared to confirm the full specification with Star first

Frequently Asked Questions

01 What bar size does the Star SR-10R take?

The bar capacity row gives 10 mm (0.394 in). Other rows of the same table state different diameters, so do not size a job from this page alone. Ask Star for the specification sheet of the exact type you are being quoted.

02 How many axes does the SR-10R have?

Up to 7: X1, Z1, X2, Z2, Y1, C1 and C2. The Y-axis stroke is ±8 mm. There is no Y2 in the list, so off-centre work on the back end is not available, and features there are positioned with C2.

03 Which control does the SR-10R use?

It depends on the type. The table gives Fanuc 31i-B for Type A and Fanuc 31i-B5 for Type B. It does not say what else separates the two types, so ask Star which machine functions come with each.

04 What are the weight and floor space of the SR-10R?

Star lists a machine weight of 2,600 kg and a floor space of 2,334 x 1,200 x 1,700 mm, with a coolant capacity of 170 L. Add the bar feeder and service access to that footprint when laying out the cell.
