Overview

The Star SV-32R is a high-capability 32mm Swiss-type CNC automatic lathe incorporating a B-axis for true 5-axis contouring capability, positioning it among the most capable Swiss-type machines available for complex precision components. The 'SV' designation reflects Star's premium Swiss-type platform, '32' indicates the bar capacity class, and 'R' confirms the back spindle for complete part machining. The B-axis—a rotary axis allowing the tool spindle to tilt—unlocks multi-plane machining, angled hole patterns, tapered threads, and complex 3D surface machining that is impossible with conventional Swiss-type axis arrangements.

The B-axis capability makes the SV-32R particularly valuable in medical device manufacturing, where complex implant geometries increasingly demand multi-plane machining in a single setup. Orthopedic screws with complex drive geometries, dental abutments requiring conical features at compound angles, and surgical instruments with asymmetric profiles are examples of parts that benefit directly from B-axis capability. Aerospace applications including complex hydraulic fittings and sensor housings with angular ports also utilize the SV-32R's expanded machining envelope.

The SV-32R operates on Star's proven SV platform with Fanuc or Mitsubishi control, providing multi-axis coordinated machining with simultaneous front and back spindle operations. The machine's live tooling complements the B-axis capability, enabling angled milling, off-axis drilling, and compound-angle thread milling without workpiece repositioning. Star's guide bushing system maintains the precision essential for medical and aerospace tolerances even during complex 5-axis operations.

For shops producing complex 32mm precision parts that currently require expensive 5-axis machining centers for secondary operations, the SV-32R offers the possibility of completing these parts in a single Swiss-type cycle, dramatically reducing cycle time, handling, fixturing, and WIP inventory costs.

Best For

Medical device manufacturers producing complex orthopedic screws, dental abutments, and surgical instruments with compound-angle features Aerospace suppliers machining complex connectors, sensor housings, and hydraulic components with angled ports and non-orthogonal features Contract manufacturers competing for the most complex Swiss-type work—parts that competitors cannot complete in a single setup Shops currently using separate Swiss lathes and 5-axis machining centers in sequence, seeking to consolidate into a single SV-32R cycle Defense component manufacturers requiring complex precision parts with tight multi-plane geometric tolerances High-value precision parts producers where reduced WIP, handling, and fixturing costs justify the SV-32R premium

Frequently Asked Questions

01 What does the B-axis do on the Star SV-32R?

The B-axis rotates the live tool spindle up to ±45° from the standard perpendicular orientation. This enables drilling and milling at compound angles to the part centerline, machining tapered threads, creating complex angled features like angled cross-holes and conical surfaces, and 3D surface contouring—all without repositioning the workpiece. This eliminates secondary 5-axis machining center operations for parts with these features.

02 What is the Star SV-32R price?

A new Star SV-32R ranges from approximately $250,000 to $380,000 depending on axis configuration, tooling package, and control selection. The B-axis commands a significant premium over standard SR and SV models without this capability.

03 How does the SV-32R compare to the SR-32J?

The SR-32J is Star's high-production 32mm Swiss lathe optimized for cycle time and tooling density. The SV-32R adds the B-axis for parts requiring compound-angle machining. If your parts don't need angled features beyond standard Y-axis capability, the SR-32J delivers comparable throughput at a lower cost. The SV-32R's premium is justified only when B-axis capability genuinely eliminates secondary operations.

04 What CAM software supports 5-axis programming for the SV-32R?

ESPRIT (now DP Technology), Mastercam Swiss, and Citizen-compatible Swiss CAM packages with B-axis post-processors support the SV-32R's 5-axis capability. Star's applications team provides post-processor support and application guidance. Programming verification using simulation software like VERICUT or NCSimul is strongly recommended for complex B-axis programs.

05 Is the SV-32R available with non-guide bushing (NGB)?

Yes, certain SV-32R configurations support NGB operation for shorter parts where material savings are important. The guide bushing mode remains preferred for precision and long parts. Consult Star Micronics applications specialists to determine whether guide bushing or NGB is optimal for your specific part family.
