Overview

The Star Micronics SV-32 is a Swiss-type CNC sliding headstock lathe with an integrated secondary spindle, built for complete machining of bar stock up to 32 mm in diameter. The SV-series designation reflects Star's emphasis on sub-spindle versatility — the machine is configured from the outset for comprehensive back-working operations, allowing both faces of a part to be machined to completion in a single continuous cycle without operator intervention or secondary fixturing.

The SV-32 incorporates a V-shaped slant tool arrangement that Star has developed across its SV-series lineup. This tooling geometry positions turning and driven tools at optimized angles relative to the workpiece, improving chip evacuation and reducing the potential for chip re-cutting on Swiss parts where continuous chip formation in a confined machining zone is a persistent quality risk. The slant arrangement also enables compact tooling packages that maintain accessibility for setup and tool changes without requiring operators to reach deep into the machining zone.

For live tool operations, the SV-32 supports driven tooling on both the main spindle and sub-spindle sides, enabling milling, drilling, cross-drilling, and thread milling on both part faces. The machine's control coordinates live tool operations with turning moves in simultaneous multi-axis cycles, reducing total cycle time on parts that require extensive driven tool work. Star's SV-series architecture is particularly well-regarded for its efficiency on connector, valve, and medical component production where both ends of the part carry complex features.

Star Micronics positions the SV-32 as a production-optimized machine for shops running medium-to-high volumes of complete Swiss-turned parts. The FANUC control platform provides broad CAM compatibility and operator familiarity, while Star's factory application engineering team supports tooling layout, programming strategies, and cycle time optimization for new part introductions. The machine competes directly with Citizen's Cincom L32 and Tsugami's B0326 in the 32 mm complete-machining Swiss lathe market.

Strengths & Limitations

Strengths

Dual 10,000 rpm spindles with comprehensive sub-spindle back-working capability support complete part machining in a single cycle
V-slant tooling geometry improves chip evacuation in the machining zone, reducing chip re-cutting risk on precision Swiss components
Up to 9 simultaneous axes with live tools on both main and sub-spindle sides — strong capability for complex connector and medical component production
FANUC 32i-B control provides broad CAM software compatibility and simplified operator training for shops with existing FANUC equipment

Limitations

Live tool speed limited to 6,000 rpm — high-speed milling strategies on hardened materials may be constrained relative to higher-speed competing machines
V-slant tooling arrangement requires familiarity with Star's specific tooling system — tooling sourcing and setup differ from conventional gang-plate Swiss lathes
Base machine configuration may require additional optional tooling units to reach full 9-axis capability, increasing total investment

Best For

Production shops machining connector bodies, valve components, and hydraulic fittings requiring complete machining on both ends in a single cycle Medical device manufacturers running stainless steel and titanium implant and instrument components where back-working quality is critical Swiss machining job shops standardizing on FANUC-based controls for fleet-wide programming and operator cross-training efficiency Precision parts producers where V-slant chip control reduces scrap from chip re-cutting on high-value aerospace and medical workpieces

Frequently Asked Questions

01 What does the 'SV' designation mean in the Star Micronics SV-32?

The SV designation in Star's naming convention refers to the machine's sub-spindle and V-slant tooling configuration. SV-series machines are designed from the outset for complete machining with comprehensive back-working capability on the sub-spindle, as opposed to simpler Swiss lathes where sub-spindle capability is more limited. The V-slant tool arrangement is a Star design feature intended to improve chip flow and access in the machining zone.

02 How does the Star SV-32 compare to the Star SR-32J?

The SV-32 and SR-32J are both 32 mm Swiss lathes from Star Micronics, but differ in tooling architecture and sub-spindle emphasis. The SV-32 features Star's V-slant tooling arrangement and is configured with equal emphasis on main and sub-spindle live tool capacity, making it particularly strong for complete back-working-intensive parts. The SR-32J emphasizes overlapping axis motion for cycle time efficiency and is well-suited for high-volume parts where cycle speed is the primary priority. Selection between the two depends on part geometry and production priorities.

03 Is the Star Micronics SV-32 suitable for medical device production?

Yes. The SV-32 is well-suited for medical device component production, particularly for parts requiring complete machining on both ends such as bone screws, cannulas, dental implant components, and surgical instrument handles. The machine's dual 10,000 rpm spindles, live tool capacity on both sides, and guide bushing support for slender workpieces align with the requirements of medical Swiss machining. Many medical device contract manufacturers use the SV-series as a primary platform.
