PUMA TT1800SY Twin-Spindle Turning Center with Y-Axis Milling

The PUMA TT1800SY is a DN Solutions twin-spindle, twin-turret turning center built for high-volume production of small to medium-diameter parts that need turning, milling, and drilling completed in a single setup. Two 22 kW (30 hp), 5,000 RPM spindles and two 12-station BMT-55 turrets run simultaneously, while Y-axis travel on the upper turret adds off-center milling and drilling without repositioning the part. The machine holds a 9.05 in. maximum turning diameter and accepts bar stock up to 2.625 in., with full C-axis contouring on both the main and right spindle. Ellison Technologies, the largest DN Solutions distributor in North America, supplies the TT1800SY as part of its mill/turn center lineup for shops that need complete parts off one machine instead of running separate turning and milling operations.

Applications and Industries

Automotive and Fluid Power Components

Valve bodies, manifolds, fittings, and small housings for automotive and fluid power suppliers typically need turning, cross-drilling, and milling completed without a second setup, exactly what the TT1800SY's opposed spindles and Y-axis upper turret are built for. A part can be turned and drilled complete on the main spindle, transferred to the right spindle for back-side work, and finished with off-center milling from the Y-axis turret, all in one cycle. The 1,575 ipm Z-axis rapid traverse and 0.15-second turret index keep non-cutting time low on the high-volume runs these industries require.

Medical Device and Precision Small-Part Manufacturing

Medical device shops running small, tight-tolerance components such as connectors, couplings, and instrument housings benefit from the TT1800SY's ±0.002 mm axis repeatability and full C-axis contouring on both spindles. Complete-in-one-setup processing removes the handling and re-fixturing steps that introduce error on small parts, and the spindle chillers hold thermal stability through long unattended runs common in medical production.

Semiconductor and Electronics Connector Components

Connector bodies, fittings, and small precision housings for semiconductor and electronics manufacturers need consistent, repeatable turning on parts too small to justify a full-size lathe running one operation at a time. The TT1800SY's twin-spindle, twin-turret layout with live tooling on all 24 stations lets these shops turn, mill, and drill complete parts in the same cycle time it would take a single-spindle machine to finish roughing.

Powerful Dual-Turret Architecture with Y-Axis Precision

The TT1800SY’s upper turret is equipped with Y-axis travel of ±2.05", enabling off-center milling, drilling, and tapping in a single setup. Its lower turret supports both main and sub-spindle operations for full part handoff machining. With live tooling, servo-driven indexing, and C-axis control on both spindles, users can program mirror operations or simultaneous front/back work for unmatched efficiency.

  • Max Turning Diameter: 10.2"

  • Max Turning Length: 20.9"

  • Chuck Size: 8" (main and sub)

  • Bar Capacity: 2.6"

  • Spindle Speed: 4,500 rpm

  • Turret Tool Stations: 12 upper, 12 lower

Engineered for Stability, Accuracy, and Longevity

A heavy-duty slant-bed casting provides the rigidity needed for aggressive turning and live milling. Ball screw cooling and spindle chiller systems maintain thermal stability across long cycles. LM roller-type guideways on all axes support high-speed movements while minimizing vibration. Indexing time of 0.2 seconds per turret position and high-power live tools (up to 5,000 rpm) keep the spindle engaged longer—boosting part output without sacrificing precision.

Automation Ready with Tool Monitoring and Probing Options

The PUMA TT1800SY is designed for integration with bar feeders, gantry loaders, or robotic automation. Its tool load monitoring system detects overload or missing tools, while optional probing systems simplify part alignment and in-process inspection. With fast turret indexing, a sub-spindle with full C-axis control, and programmable tailstock support, this machine reduces downtime and maximizes spindle utilization.

Key features include:

  • Manual Pulse Generator (MPG)

  • Through-turret and through-spindle coolant

  • Fanuc iHMI touchscreen control interface

  • Automatic tool presetter

  • Coolant chiller and chip management system

FAQ Section

What is the PUMA TT1800SY used for?

The PUMA TT1800SY is a twin-spindle, twin-turret mill/turn center used for high-volume production of parts that need turning, milling, drilling, and tapping finished in a single setup, including valve components, connector bodies, housings, and medium-diameter shaft work. Its two 22 kW spindles and Y-axis upper turret make it a fit for shops replacing multiple separate operations with one continuous cycle.

How does the PUMA TT1800SY compare to a single-spindle turning center?

A single-spindle lathe finishes one side of a part, then needs a second setup or a separate mill to complete back-side or off-center features. The TT1800SY's opposed spindles pass the part from the main spindle to the right spindle for complete machining, and its Y-axis upper turret adds off-center milling and drilling, cutting the total operations needed to finish a complex part.

What industries is the PUMA TT1800SY best suited for?

The TT1800SY's combination of twin-spindle transfer, Y-axis milling, and tight axis repeatability fits automotive and fluid power component production, medical device and precision small-part manufacturing, and semiconductor and electronics connector work, anywhere small to medium-diameter parts need to be finished complete in one cycle.

What is the maximum bar capacity of the PUMA TT1800SY?

The PUMA TT1800SY accepts bar stock up to 2.625 in. (67 mm) in diameter, with a maximum bar length of 42 in. (1,067 mm) for bar-fed applications.

What control does the PUMA TT1800SY run?

The PUMA TT1800SY uses a FANUC 0i-Plus control with an iHMi touch screen interface and a swiveling operator's panel, including EZ Guide i conversational programming and a tool load monitoring system.
