Overview

The Hardinge SR-200 is a Swiss-type CNC sliding-headstock lathe designed for high-precision production of small, slender parts. With a maximum bar capacity of 20 mm (0.787 in) and a guide bushing that supports the workpiece at the cutting zone, the SR-200 achieves the kind of length-to-diameter ratios and surface finishes that fixed-headstock lathes simply cannot match. This is the machine precision medical, dental, and watchmaking shops turn to when tolerances are measured in single-digit microns and surface finish must be flawless.

The SR-200's sliding headstock design feeds bar stock through a precision guide bushing, supporting the workpiece immediately adjacent to the cutting point. This eliminates deflection on long, slender parts — a fundamental advantage over conventional CNC lathes. The main spindle delivers up to 10,000 RPM with 3.7 kW (5 hp) continuous power, optimized for the small-diameter, high-surface-speed cutting that Swiss-type work demands. The sub-spindle provides back-working capability at 8,000 RPM for complete part processing without secondary operations.

The SR-200 features up to 7 axes of simultaneous control, with gang-type and turret tooling configurations that accommodate both turning and milling operations. Live tooling positions enable cross-drilling, milling flats, and threading operations. The machine includes a C-axis on both main and sub-spindle for positioned and contoured milling work. Y-axis capability on the gang slide provides off-center milling and drilling capability that would otherwise require a secondary machining operation.

Running on a Fanuc 31i-B control, the SR-200 provides the processing power needed for complex multi-axis simultaneous interpolation. Hardinge positions the SR-200 against the Citizen L20, Star SR-20, and Tsugami B0205 in the 20 mm Swiss-type segment. New SR-200 machines price between $150,000 and $250,000 depending on axis configuration and tooling. Specs derived from Hardinge published data and industry documentation.

Strengths & Limitations

Strengths

Sliding-headstock design with guide bushing eliminates workpiece deflection, enabling length-to-diameter ratios exceeding 10:1 with sub-micron accuracy
Sub-spindle with back-working capability enables complete part processing in a single cycle, eliminating secondary operations and part handling
Y-axis capability on the gang slide provides off-center milling and drilling without requiring a secondary machine
Up to 7 axes of simultaneous control allow complex Swiss-type parts with milled features, cross-holes, and contoured profiles
Removable guide bushing option allows the machine to operate in both Swiss-type and conventional fixed-headstock modes
Fanuc 31i-B control provides the processing power for complex multi-axis simultaneous interpolation with full look-ahead capability

Limitations

20 mm maximum bar capacity limits the SR-200 to small parts — shops needing to turn parts above 20 mm diameter need a larger Swiss-type or conventional lathe
Swiss-type machines require specialized operator training beyond conventional CNC lathe experience, increasing onboarding costs for shops new to Swiss turning
Bar stock must be precision-ground for guide bushing operation, adding material cost compared to standard drawn bar used on conventional lathes
Higher price point than conventional CNC lathes of similar spindle power reflects the added complexity of sliding-headstock multi-axis capability

Best For

Medical device manufacturers producing bone screws, dental implants, surgical instrument shafts, and guidewire components requiring extreme precision on long, slender geometries Watchmaking and micro-mechanism shops producing precision pins, shafts, and turned components with single-digit micron tolerances Aerospace fastener and fitting manufacturers producing small-diameter precision hardware in titanium, Inconel, and high-strength stainless steels Automotive fuel injection and hydraulic component producers needing high-volume production of precision small parts with complex features Electronics connector manufacturers producing precision contact pins, sockets, and terminal components at high volumes

Frequently Asked Questions

01 What does a new Hardinge SR-200 cost?

New Hardinge SR-200 machines typically price between $150,000 and $250,000 depending on axis configuration, tooling package, and options. Base 5-axis configurations start at the lower end, while fully loaded 7-axis machines with Y-axis, sub-spindle, and extensive live tooling reach the upper range. Used SR-200 machines from 2015-2022 trade between $75,000 and $150,000.

02 How does the SR-200 compare to the Citizen L20?

Both are 20 mm Swiss-type lathes targeting the same precision small-parts market. The Citizen L20 has a larger installed base globally and Citizen's LFV chip-breaking technology is a significant advantage for stringy materials. The Hardinge SR-200 offers Hardinge's precision spindle heritage and is often preferred by shops already running Hardinge equipment. Both deliver comparable precision and productivity.

03 Can the SR-200 run without the guide bushing?

Yes. The SR-200 features a removable guide bushing system that allows the machine to operate in non-guide-bushing mode for shorter parts where the guide bushing is not needed. This reduces bar remnant waste and eliminates the requirement for ground bar stock, lowering material costs for parts that do not require guide bushing support.

04 What materials can the SR-200 handle?

The SR-200 handles the full range of Swiss-type materials including free-machining brass, aluminum alloys, stainless steels (303, 304, 316), titanium (Grade 2, Grade 5), Inconel, PEEK, and other engineering plastics. The spindle speed range and tooling options are optimized for the small-diameter, high-surface-speed cutting these materials require in Swiss-type applications.
