Overview

The Doosan Lynx 220LSYC is a fully configured mill-turn CNC lathe combining Y-axis cross-milling, a lower sub-spindle (C-axis), and live tooling in a compact 8-inch (220mm) chuck platform. The LSYC designation indicates the machine's full feature set: L for live tooling, S for sub-spindle, Y for Y-axis, and C for C-axis. This configuration enables complete part production — main spindle turning, off-centerline milling, sub-spindle backworking, and bar-fed production — in a single machine without any secondary operations. The Lynx 220LSYC targets high-complexity rotational parts in automotive, medical device, hydraulics, and precision component manufacturing.

Built on the proven Lynx 220 platform with a 45-degree slant-bed and 220mm maximum swing, the LSYC variant adds a ±52mm Y-axis stroke to the cross-slide, driven tooling with speeds up to 6,000 RPM, and a lower sub-spindle with C-axis indexing and 4,000 RPM capability for complete backwork. The main spindle runs to 6,000 RPM with 18.5 kW of power, providing adequate torque for stainless, alloy steel, and titanium turning. Bar-fed production is supported through the machine's 51mm spindle bore and standard parts catcher.

DN Solutions (formerly Doosan Machine Tools) supports the Lynx 220LSYC through an extensive North American and European dealer and service network, providing application engineering, programming support, and parts availability that distinguishes the machine from similar-spec Korean competitors. The Fanuc 0iTF control with multi-axis capability is standard, with conversational programming cycles for common turning, milling, and sub-spindle operations. Full enclosure and programmable coolant support long-run production and lights-out operation.

The Lynx 220LSYC competes with the Mazak Quick Turn Nexus 250-II MSY, Okuma LB3000 EX MY, and Hyundai WIA L230MSY in the full-featured 8-inch mill-turn sub-spindle class. Pricing typically ranges from $180,000 to $260,000. For shops requiring the highest level of single-setup part completion capability in the compact lathe class, the Lynx 220LSYC delivers a comprehensive and well-supported production platform.

Strengths & Limitations

Strengths

Full LSYC configuration — live tooling, sub-spindle, Y-axis, C-axis — enables complete part production from bar stock in a single setup, eliminating all secondary turning, milling, and drilling operations
DN Solutions' extensive North American and European dealer network provides application engineering support, programming assistance, and parts availability that gives the Lynx 220LSYC a service infrastructure advantage over smaller Korean brands
±52mm Y-axis stroke combined with 6,000 RPM driven tooling handles off-centerline features including cross-holes, keyways, hexagonal profiles, and eccentric bores typical in medical, automotive, and hydraulic component production
Fanuc 0iTF control with full multi-axis support and conversational cycles reduces programming complexity for shops setting up new part families and provides broad CAM post processor compatibility

Limitations

Premium pricing versus 2-axis or Y-axis-only alternatives — the full LSYC configuration adds significant cost that is only justified when sub-spindle backworking eliminates meaningful secondary operations
51mm spindle bore limits bar capacity compared to lathes with larger bore options — shops running barstock above 51mm will need to verify compatibility with their bar feeder configuration
Programming complexity for full multi-axis mill-turn with sub-spindle synchronization requires experienced programmers or robust CAM software — shops new to mill-turn may face a longer learning curve

Best For

Medical device manufacturers producing complex turned components — bone screws, implant features, cannulas, and surgical instrument bodies — that require complete 5-sided machining from bar stock in a single setup Automotive and hydraulic component suppliers machining valve bodies, fittings, and multi-feature shaft assemblies where complete machining in one setup reduces cycle time and eliminates transfer fixturing High-mix precision job shops looking to consolidate turning, milling, drilling, and backwork onto a single capable platform to reduce WIP, setup time, and floor space Production facilities running lights-out bar-fed production of complex rotational components where single-setup completion and parts catcher integration maximize unattended output

Frequently Asked Questions

01 What does the LSYC designation mean on the Doosan Lynx 220LSYC?

The LSYC suffix indicates the machine's full feature configuration: L = Live tooling (driven tools in the turret), S = Sub-spindle (lower spindle for backworking the second side of parts), Y = Y-axis (cross-slide stroke for off-centerline milling), and C = C-axis (spindle orientation and contouring on both main and sub spindle). The 220 in the name refers to the 220mm maximum chuck size. The full LSYC configuration enables complete part machining from a single bar-fed setup.

02 Can the Lynx 220LSYC run unattended lights-out production?

Yes. With bar feeder integration, parts catcher, Fanuc tool life management, and part probing options, the Lynx 220LSYC is well-suited for lights-out and unattended production of proven programs. DN Solutions offers optional automation packages including robotic loading interfaces. The machine's rigid slant-bed construction and thermal compensation support consistent dimensional accuracy across long production runs without operator intervention.

03 What is the sub-spindle capacity of the Lynx 220LSYC?

The lower sub-spindle on the Lynx 220LSYC accepts a 6-inch (165mm) chuck and runs to 6,000 RPM, with live tooling capability for backwork milling and drilling operations. The sub-spindle transfers parts from the main spindle automatically via programmed synchronization — no manual part transfer is required. This allows complete OD, ID, facing, and off-centerline features on both ends of the part without operator intervention.

04 How does the Lynx 220LSYC compare to the Mazak Quick Turn Nexus 250-II MSY?

Both machines compete in the compact mill-turn class with Y-axis and live tooling capability, though the Mazak typically does not include a sub-spindle in the standard MSY configuration. The Mazak Quick Turn Nexus runs the Mazatrol SmoothG control with strong conversational programming, while the Lynx 220LSYC uses Fanuc 0iTF — a key differentiator for shops with control preferences. The Lynx 220LSYC's sub-spindle adds a capability level not present on the Mazak MSY. Shops requiring backwork should favor the Lynx 220LSYC; shops that can live without sub-spindle may find the Mazak more cost-effective.

05 What CAM systems are recommended for programming the Lynx 220LSYC?

Mastercam, Siemens NX, ESPRIT, and Fusion 360 (with turn-mill modules) all support full Lynx 220LSYC multi-axis programming with DN Solutions / Fanuc posts. ESPRIT and NX are particularly strong for complex simultaneous multi-axis mill-turn programs. DN Solutions applications engineers can advise on post processor selection and provide application programming support for complex parts during machine installation and commissioning.
