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-32JII Type A/B is a 32 mm (1.26 in) Swiss-type lathe listed with up to 10 axes, including Y1, Y2, C1 and C2. The second Y axis and the pair of C axes are what the table puts first. Read in the usual way, Y2 and C2 belong to the back-working side, so off-centre milling and drilling can be programmed on both ends of a part with each spindle positioned or rotated under control.

Live tools run to 8,000 RPM, the same top speed as the main and sub-spindles. That handles cross drilling and slotting in steel and stainless comfortably. Very small end mills in brass or aluminium would want more, so work out the surface speed for the smallest cutter on the job.

Spindle power is 7.5 kW continuous and 11.0 kW (10min./25%ED) on the main side, 3.7 kW continuous and 5.5 kW (10min/40%ED) on the sub-spindle. Maximum machining length matches the 320 mm (12-19/32 in) headstock stroke, and six turning tools are listed. Bar capacity is Ø32 mm (1-1/4 in), with Ø34 mm (1-11/32 in) as an option.

Power consumption is listed at 12 kVA and the footprint at 2,690 × 1,345 × 1,780 mm. Weight, spindle speed and rapids match the SR-32J: 4,100 kg, 8,000 rpm and 35 m/min. One caution: the listing covers Type A and Type B together, and the table does not say where the two differ. Establish which type a quotation covers and what that changes.

Strengths & Limitations

Strengths

Up to 10 axes including Y1, Y2, C1 and C2, so both ends of a part can take off-centre features
Live tools run to 8,000 RPM, matching the spindle speed
320 mm (12.6 in) maximum machining length on a 32 mm (1.26 in) bar
Power consumption of 12 kVA is stated for sizing the supply
Bar capacity can be raised from Ø32 mm (1-1/4 in) to Ø34 mm (1-11/32 in) as an option

Limitations

The table does not separate Type A from Type B, so the difference has to be confirmed with the seller
Axis count is given as 'up to 10', which leaves the count on a given machine open
No rapid traverse figure is given for Y2; the 35 m/min figure covers X1, X2, Y1, Z1 and Z2
Sub-spindle power is 3.7 kW continuous against 7.5 kW on the main spindle

Best For

Parts with milled flats or off-centre holes on both ends Complete machining of bar parts up to 32 mm (1.26 in) diameter Long components up to 320 mm (12.6 in) machining length Cross drilling and slotting with live tools at up to 8,000 RPM

Frequently Asked Questions

01 What is the difference between SR-32JII Type A and Type B?

The table for this listing does not say. It gives one set of figures for both types: up to 10 axes including Y1, Y2, C1 and C2, a 32 mm (1.26 in) machining diameter and a 320 mm (12.6 in) machining length. Ask the seller which type is being offered and what differs before comparing quotations.

02 How does the SR-32JII compare with the SR-32J?

On size and speed the two are listed alike: the SR-32J also weighs 4,100 kg, runs its main spindle at 8,000 rpm with 7.5 kW continuous, and rapids at 35 m/min. The SR-32JII table adds an 8,000 RPM live tool speed and names Y1, Y2, C1 and C2 among up to 10 axes.

03 How fast do the live tools run on the SR-32JII?

Live tool speed is listed at 8,000 RPM. The main spindle and sub-spindle are also listed at 8,000 rpm. Calculate the surface speed for the smallest drill or end mill on the job to see whether that is enough in the material being cut.

04 What power supply does the SR-32JII need?

Power consumption is listed at 12 kVA. The main spindle motor is 7.5 kW continuous and 11.0 kW (10min./25%ED); the sub-spindle motor is 3.7 kW continuous and 5.5 kW (10min/40%ED). Supply voltage is not given in the table.
