Overview

The Star SD-32 Type S is a 32mm Swiss-type CNC automatic lathe in Star's SD (Swiss Direct) series, with the 'Type S' designation indicating a specific configuration variant optimized for particular machining requirements within the 32mm capacity class. The SD series occupies a middle position in Star's product family—more capable than the ECAS platform but differentiated from the full SR series in its specific feature set and price positioning.

The SD-32 Type S serves the 32mm precision parts market with an emphasis on direct-drive spindle technology, efficient tooling layouts, and the combination of turning and live tooling operations necessary for medium-complexity parts. At 32mm, the machine addresses a broad range of industrial precision components: automotive fuel system parts, industrial connectors, hydraulic fittings, medical device components, and electronic hardware produced in medium-to-high volumes.

The Type S configuration specifically addresses applications requiring enhanced live tooling performance or specific tooling layout arrangements that differentiate it from the standard SD-32. Star Micronics' SD platform benefits from proven guide bushing technology for precision and surface quality on longer parts, and a Fanuc control provides programming accessibility for operators transitioning from conventional CNC turning or other Swiss-type platforms.

For shops seeking a balance between the operational simplicity of the ECAS series and the full capability complexity of the SR series, the SD-32 Type S represents a practical Swiss-type solution for the extensive range of medium-complexity 32mm precision parts that represent the bread-and-butter of Swiss-type manufacturing.

Best For

Contract manufacturers producing medium-complexity precision parts in the 20-32mm range that require off-center milling but not the full SR series' capability Automotive suppliers machining fuel system components, sensors, and connectors in medium-to-high volumes Medical device manufacturers producing moderate-complexity device components where SD pricing is more appropriate than SR investment Shops transitioning from simple Swiss-type platforms (ECAS, SB) to more capable multi-axis configurations Industrial precision parts producers needing Y-axis capability for hex and flat features without full SR-class investment Job shops seeking a versatile 32mm Swiss lathe for diverse customer parts at a practical price point

Frequently Asked Questions

01 What is the 'Type S' designation on the Star SD-32?

The 'Type S' designation on Star Micronics Swiss-type lathes typically indicates a specific configuration variant within the SD series—often related to tooling system, live tool arrangement, or functional specification differences compared to the standard SD-32. Confirm the specific Type S features with Star Micronics or their distributor for the current production configuration.

02 How does the SD-32 Type S compare to the SR-32J?

The SR-32J is Star's high-production 32mm Swiss lathe with more axes, greater tooling density, and the full MCS multi-path machining optimization system. The SD-32 Type S is positioned below the SR series with adequate capability for medium-complexity parts at a lower price. For complex parts requiring maximum simultaneous machining capability, the SR-32J is the better choice.

03 What does a Star SD-32 Type S cost?

A new Star SD-32 Type S typically ranges from approximately $190,000 to $280,000 depending on configuration and tooling options. Used SD-32 machines sell in the $70,000–$130,000 range depending on age, condition, and specification.

04 Can the SD-32 Type S machine stainless steel effectively?

Yes. The 9,000 RPM spindle and adequate torque handle 303 and 316L stainless steel routinely. For 316L and other tougher stainless grades, sharp coated carbide tooling and optimized feed rates are important. The guide bushing system helps maintain consistent surface finish and tolerances on stainless parts where chatter is a concern.

05 What control does the SD-32 Type S use?

The SD-32 Type S uses the Fanuc 31i-B5 control, providing broad programmer familiarity, an extensive ecosystem of third-party programming tools, and a large pool of experienced operators—reducing training costs and easing the transition from other Fanuc-equipped machines.
