Overview
The Star SV-32 is Star Micronics' high-performance Swiss-type CNC automatic lathe for the 32mm bar capacity class, delivering the maximum capability and precision available from Star in this critical bar size. The SV (High-Performance) designation places the SV-32 above the SR-32J in Star's hierarchy, with higher spindle speeds, more tooling capacity, and enhanced rigidity designed for the most demanding 32mm Swiss applications in medical, aerospace, and defense manufacturing.
The SV-32 features a main spindle reaching 10,000 RPM—2,000 RPM faster than the SR-32J's 8,000 RPM—and a back spindle at 10,000 RPM, providing balanced high-speed capability for both front and back operations. At the 32mm bar size, this speed advantage is significant for finishing operations on smaller-diameter features and for achieving optimal cutting conditions on materials that benefit from higher surface speeds. With up to 10 axes including B-axis capability and up to 35 tool positions, the SV-32 is one of the most capable Swiss-type lathes available in any bar size.
The B-axis option transforms the SV-32 from a Swiss lathe into a true multi-tasking machine. Angular drilling, milling, and tapping operations that traditionally required secondary setups on indexing fixtures or 5-axis mills can be performed directly on the SV-32. For medical implants with compound-angle screw holes, aerospace fittings with angular ports, and defense components with complex geometries, the B-axis eliminates entire secondary operations from the manufacturing process.
Star's hydraulic-free design, Motion Control System, and advanced thermal management work together to deliver the precision and consistency that high-performance 32mm Swiss work demands. The Fanuc 31i-B5 control provides the processing power for complex synchronized programs, and Star's programming environment simplifies the creation of multi-path operations with B-axis coordination.

Frequently Asked Questions
01
A new Star SV-32 ranges from approximately $350,000 for a standard configuration to $520,000 for a fully equipped model with B-axis and maximum tooling. With bar feeder, chip conveyor, and initial tooling, total investment typically exceeds $450,000-$650,000.
02
The SV-32 is justified when you need the 10,000 RPM spindle speed for better surface finishes, the B-axis for angular features that currently require secondary operations, or the 35-position tool capacity for maximum complexity. If your parts run well on the SR-32J's 8,000 RPM with 30 tools, the premium is not justified.
03
Both are top-tier 32mm Swiss lathes. The SV-32 offers higher spindle speed (10,000 vs 8,000 RPM), hydraulic-free design, and Star's MCS. The Citizen L32 XII offers up to 44 tool positions, LFV chip-breaking, and its own B-axis. For speed-critical finishing, the SV-32 has the edge. For maximum tooling density and chip control in gummy materials, the Citizen L32 XII is compelling.
04
The B-axis adds approximately $40,000-$60,000 to the machine cost. It's worth it if you currently perform secondary operations for angular features on Swiss parts, as the labor, handling, and quality costs of secondary operations often exceed the B-axis investment within 12-18 months of high-utilization production.
05
Spinal pedicle screws with hexalobular drives and compound-angle cannulations, tibial baseplates with angular locking features, and complex trauma hardware with multi-angle screw holes are ideal SV-32 applications. Any medical component in the 20-32mm range with angular features that currently require secondary operations after Swiss machining is a strong candidate.
