Overview

The Star SW-38 is a 38mm sliding headstock CNC automatic lathe positioned in Star's SW (Swiss Wide) series, designed to deliver high tooling capacity and operational flexibility for complex parts in the 25-38mm diameter range. The SW series emphasizes maximizing the number of simultaneous tools in cut and the variety of operations achievable within a single machine cycle, making it particularly attractive for parts that would otherwise require multiple setups or post-process secondary operations.

The SW-38's 38mm bar capacity expands the range of complex components addressable with Swiss-type efficiency: larger medical implants, aerospace connectors, and precision industrial components that combine turning, milling, drilling, and threading in demanding sequences. The machine provides a Y-axis as standard, enabling true off-center milling that is essential for flats, hexagons, and keyways on larger-diameter parts without the need for C-axis interpolation compromises.

Star's SW series design philosophy emphasizes gang-tool efficiency combined with live tooling density, giving process engineers broad flexibility in optimizing tool layouts for specific part families. The machine's guide bushing system maintains the precision and surface quality that define Swiss-type machining even at 38mm diameter, ensuring that part quality meets medical and aerospace requirements.

With a Mitsubishi control option available alongside Fanuc, the SW-38 gives shops control platform flexibility to match their existing infrastructure. Star's hydraulic-free design approach on the SW series reduces maintenance overhead and environmental compliance costs, consistent with Star Micronics' design philosophy across its premium product lines.

Frequently Asked Questions

01 How does the Star SW-38 differ from the SR-38?

Both are premium 38mm Swiss-type lathes with Y-axis capability and multi-axis machining. The SW series emphasizes wide gang tooling with high tooling density and is offered with Mitsubishi control options, while the SR series is built around Star's MCS (Motion Control System) for optimized cycle time coordination. The choice often comes down to control preference and specific tooling layout requirements.

02 What is the price of a Star SW-38?

A new Star SW-38 ranges from approximately $210,000 to $310,000 depending on axis configuration, tooling package, and control selection. Used SW-38 machines typically sell for $80,000–$150,000 depending on age, hours, and specification.

03 Does the SW-38 support non-guide bushing (NGB) operation?

Certain SW-38 configurations support NGB operation, which reduces bar remnant waste for shorter parts. Guide bushing mode remains standard and preferred for precision work and longer parts. Contact Star Micronics' applications team to confirm NGB availability for specific configurations.

04 What materials does the SW-38 machine effectively?

The SW-38 handles all standard Swiss-type materials: free-machining steel (12L14, 1215), stainless steel (303, 304, 316L), titanium (Ti-6Al-4V), aluminum, and brass. Medical-grade materials including PEEK and cobalt-chrome are also within the machine's capability with appropriate tooling.

05 Is the Mitsubishi M830 control available on all SW-38 configurations?

Mitsubishi M830 control availability depends on the specific configuration and market. Fanuc 31i-B5 is the primary control offering. Shops with specific Mitsubishi requirements should confirm availability with Star Micronics or their regional distributor during the quotation process.
