SB-20RIIDerby-based
Star Micronics GB, a leading provider of sliding-head lathe solutions, will host its annual Open House from 19-21 November at its Technology Centre in Derby. This event will feature live demonstrations of the latest production technologies from Star and its partners.
After attracting significant interest at recent shows in Chicago (
IMTS) and Stuttgart (
AMB), the new SB-20RII will make its UK debut. As Star’s most popular machine series, with over 27,000 SB models sold globally, the SB-20RII is expected to be popular with manufacturers in the UK and Ireland.
The SB-20RII offers various improvements to further enhance performance, versatility and ergonomics. This includes additional tool stations, increased power, higher spindle speeds, advanced control features, and improved accuracy. Despite its added capabilities, such as the ability to process components up to 25.4mm in diameter, the SB-20RII has a 10% smaller footprint than the best-selling SB-20R Type G.
Offering a total of seven axes, the main spindle platen of the SB-20RII includes six turning tools, two fixed ER-16 spindles for cross-working, plus a further three modular cross power-driven stations that accept a variety of cartridge attachments. The flexibility of the SB-20RII is further enhanced by its ability to switch between guide bush mode and non-guide bush mode.
Innovative new Eco modeIncorporating various technologies to minimise heat generation, the SB-20RII includes Star’s innovative thermal displacement correction technology to optimise accuracy, stability and machining performance. The machine is equipped with Star’s innovative new Eco mode and is compatible with the latest developments including Step Cycle Pro chip-breaking technology, last part completion mode, eccentric machining cycle and Easy Edit programming utility.
Following a successful preview at last year’s Open House event, Star GB will again showcase the SK-51 Type A fixed headstock lathe. This 2in bar capacity slant-bed machine is equipped with twin 12-station turrets, offering 7.5kW-powered driven tools on every station. It offers 5,000rev/min on the main and sub spindles, and a 640mm Z-axis stroke length on both turrets.
The machines features the advanced Fanuc iHMI control system with a 15in touchscreen that offers conversational programming dialogue, free figure contour programming and a fixed phrase insert function for the configuration of individual blocks of code to drop into the final program. Toolpath simulation is also built into the control.

The Type E variant offers a programmable B1 head with four front- and four rear-facing tools, plus an additional six cartridge positions for various attachments.
Also on display will be the SR-32JIII Type B — the latest 32mm capacity model within the popular SR series, delivering a range of enhancements including improved rigidity, upgraded swarf clearance, refined ergonomics, Step Cycle Pro chip-breaking technology and the inclusion of a sub-spindle flush pump as standard.
Meanwhile, the SP-23 is a new model capable of 1in machining, developed to optimise versatility and performance while maintaining a modest footprint. The machine is equipped with an eight-station front turning platen and a seven-spindle cross-drilling inner tool post, on which a wide variety of tooling attachments can be mounted.
The SB-16III will supersede the SB-16II — this upgraded model uses the latest generation Fanuc 0i-TF Plus CNC control system. The machine’s main spindle platen includes five turning tools, a three-spindle cross drilling unit, and a four-station drilling arm.
Completing the line-up will be the SL-10, renowned for its accuracy, efficiency and versatility within an ultra-compact footprint. The SL-10 offers six turning tools on the main side and up to five cross-working tool positions, of which four tool positions are available for cartridge attachments such as thread whirling, slotting, gear hobbing, angled drilling and polygon units.

The system delivers its highly effective ‘air-cut’ chip-breaking operation by oscillating the axis in synchronisation with the spindle rotation cycle and can be used simultaneously on both the main and sub-spindles. This oscillation-cutting method increases production efficiency by eliminating machine stoppages related to swarf entanglement and enhances tool life by reducing the temperature of the tip while in operation.
Step Cycle Pro offers a dedicated interface on the Fanuc CNC system that allows engineers to easily select the ideal program conditions and chip length for the application. It automatically adjusts the actual feed rate when the function is enabled to ensure minimal effect on cycle times and enables maximum productivity to be achieved.
Visitors will see the latest developments in bar feed technology including the FMB Turbo RS 3-38. This model features the innovative RS technology, connecting the bar feed directly to the lathe spindle by a moving guide module. By eliminating the unsupported telescopic area between the bar feed and lathe, this offers improved stability for both long and short bar stock lengths.
Also on show will be the LNS QLS 65, a feature-packed bar loader available in 1.3 and 1.6m lengths.
A comprehensive range of Star’s technical partners will also exhibit their latest developments including tooling, software, parts handling, optical measurement, high-pressure coolant, mist extraction, fire suppression and more.
Star GB’s applications, service and sales team will be on hand to share their technical knowledge, giving existing and prospective users advice on identifying the ideal solution to their requirements and maximising their return on investment. Visitors will be welcome to discuss future investment plans, technical drawings, and the various schemes and finance options available to make upgrading their equipment even more affordable.
Star GB’s Technology Centre is located in Derby alongside the Rolls-Royce factory on Raynesway and is easily accessible from the A52 and the M1 with dedicated parking. The event has an open invitation to all UK and Ireland manufacturers, opening at 9am and closing at 5pm each day from Tuesday, 19 November through to Thursday, 21 November. Refreshments and lunches will be provided for all visitors.
