2014 Star SV-38R CNC Swiss Lathe with Sub-Spindle & Bar Feeder

The Star SV-38R is a Swiss-type CNC automatic lathe from Star Micronics, a builder whose sliding-headstock machines have long been a dependable staple in precision small-parts shops. This 2014 SV-38R places a gang-type tool post and a turret-type tool post on either side of the guide bush, each controlled independently so turning, drilling, and milling operations can overlap. Capacity is 1.5 inches (38 mm) maximum machining diameter, with a maximum headstock stroke of 13.78 inches (350 mm) per chucking in guide-bush mode. The main spindle is rated to 7,000 RPM with a 7.5 kW (10 HP) continuous motor and C-axis control, and the sub-spindle also reaches 7,000 RPM and chucks up to 1.5 inches for complete back-end work. Tooling includes a gang tool post with 5 turning tools and 4 power-driven tools, a 10-station turret with live tooling rated to 5,700 RPM, and an 8-spindle back working unit with Y-axis control holding 8 stationary tools and up to 6 power-driven tools. Rapid traverse is 1,181 IPM (30 m/min). The machine runs on a Fanuc CNC control and is paired with an LNS Alpha 552 bar feeder, high pressure coolant, and a Tri-Mist mist collector for bar-fed production.

Star introduced the SV-38R as part of its re-designed SV series, and it improves on the earlier Star SV-32 where it matters most in production. Star specifies higher output power on the SV-38R main and sub-spindle motors, and on the gang tool post power-driven tool motors, compared with the SV-32, giving the SV-38R more muscle for heavier cuts and milling on 1.5-inch bar stock. The SV-38R pairs that added power with a 10-station turret alongside the gang tool post and an 8-spindle back working unit, so front-end and back-end operations can run at the same time instead of in sequence. For a shop moving up from an SV-32 or a single-tool-post Swiss, the SV-38R is built to deliver more power, more simultaneous tooling, and the ability to finish complex parts complete in one setup.
