How much does the Star Micronics SB-32 Multi-Spindle Automatic cost?
Estimated price range
Our best estimate for a multi-spindle automatic in this class — not a quote from Star Micronics. Configuration moves it a long way.
Overview
Bar capacity is the headline of the Star Micronics SB-32 Multi-Spindle Automatic: the listed maximum bar diameter is 32 mm, turned at up to 6,500 rpm on 6 spindles, with 22 kW of spindle motor power installed in total. None of this has been confirmed against a Star page. Read every figure here as a listed one and verify it on the nameplate or in the manual of the machine in question.
The spindles are paired with 6 cross slides, one per position, and an end-working unit. On 32 mm stock that arrangement suits parts where forming, turning and cut-off can be shared out so that the longest single cut, not the sum of all cuts, sets the cycle. Beyond that the table is silent on stroke, part length and tool count, so whether a given part fits has to be settled from the tooling layout of the actual machine.
Plan the installation around the weight. Approximately 14,500 kg is listed, which means a floor, crane or skates rated for it. Bar loading is described only as compatible with a front-loaded magazine bar feeder, and the control as a FANUC CNC in a Star Micronics multi-spindle configuration.

Strengths & Limitations
Strengths
- 32 mm maximum bar diameter on 6 spindles, each position with its own cross slide
- 22 kW of total installed spindle motor power for six positions cutting together
- An end-working unit is listed in addition to the 6 cross slides
Limitations
- Maximum spindle speed is 6,500 rpm, which holds back surface speed on small diameters
- At approx. 14,500 kg the machine needs heavy rigging and a floor rated for the load
- No stroke, part-length or rapid figures are listed, so part fit cannot be judged from the table

Frequently Asked Questions
01
The listed maximum bar diameter is 32 mm, with a maximum spindle speed of 6,500 rpm. The table gives no minimum diameter and no part length. All of the figures are listed ones that have not been confirmed against a Star page.
02
Spindle motor power is listed as 22 kW, described as total installed. That is the sum across the machine, shared by 6 spindles, and the table does not say how it is divided. For a part with one demanding cut, the rating at that single position is the number to ask for.
03
The table lists 6 cross slides, one per position, plus an end-working unit. It gives no tool count per slide and no stroke figures, so the detail of what each position can carry has to come from the documentation of the machine being considered.
