The Star SR-38 Type B CNC Swiss-Type Automatic Lathe combines rigid construction, advanced spindle technology, and flexible tooling for precise, complex machining. Its built-in main and sub-spindles support heavy material removal, two-tool turning, and roughing and finishing operations. An 8-spindle back-working unit enables complex parts to be completed in one operation, while B-axis capability expands machining flexibility. Star's proprietary Motion Control System reduces idle time, and energy-efficient operation supports sustainable production. Ideal for aerospace, automotive, medical, and precision manufacturing, the SR-38 Type B delivers reliable performance for demanding, quality-critical applications.
