Overview
The Spinner TL1000 is a long-bed CNC turning center from Spinner Werkzeugmaschinenfabrik, designed for turning shafts, spindles, lead screws, and other elongated rotational components that exceed the capacity of standard-length turning centers. With 1,000 mm between centers as the defining specification, the TL1000 serves aerospace, energy, and precision engineering shops that regularly machine shafts, rollers, and mandrels requiring long-center-distance support without the cost of a full heavy-duty floor lathe.
The TL1000 retains Spinner's core construction principles: stress-relieved Meehanite cast iron bed, precision-ground guideways, and rigid headstock construction. The longer bed imposes additional stiffness requirements that Spinner addresses through a ribbed bed section and, on longer configurations, a steady rest or follower rest mounting system integrated with the Z-axis carriage. The bed design maintains consistent geometric accuracy from the spindle nose to the tailstock position across the full 1,000 mm center distance — a challenge that separates purpose-built long-bed machines from short-bed machines extended with longer beds.
The main spindle accommodates workpieces appropriate for shaft turning applications: typically 400 mm swing, with an A2-6 or A2-8 nose and spindle speeds up to 4,000 RPM. Drive power of 22–30 kW provides torque for roughing stainless steel and alloy steel shaft stock at appropriate depth-of-cut. A 12-station turret handles the standard turning tool complement, with live tooling options available for shops that need to drill cross-holes, mill keyways, and thread-mill on shaft parts in a single setup.
The TL1000 is controlled by Siemens Sinumerik 840D sl or 828D as standard, with Fanuc options for export. The machine's capacity to handle 1,000 mm between centers at Spinner's accuracy standards — typically ±0.005 mm cylindricity over the full length — makes it valuable in precision shaft production where out-of-round and taper are critical quality parameters. European pricing ranges from €100,000 to €160,000 depending on turret type, live tooling, tailstock configuration, and steady rest options.

Strengths & Limitations
Strengths
- 1,000 mm between-centers capacity enables shaft, spindle, and roller turning that standard 500–600 mm turning centers cannot accommodate, eliminating the need for a dedicated shaft lathe in shops that occasionally require longer workpieces
- Stress-relieved cast iron bed maintains geometric accuracy over the full 1,000 mm working length, preventing taper and cylindricity errors that accumulate on less rigidly constructed long-bed machines
- 22–30 kW spindle drive provides adequate torque for roughing alloy steel and stainless shaft stock at productive depths of cut, reducing cycle times on heavy material removal
- Integrated steady rest and follower rest provisions allow large-diameter, long shafts to be turned without deflection, a critical capability for precision shaft work in aerospace and energy applications
Limitations
- Long-bed configuration increases machine footprint substantially — the TL1000 requires approximately 5,000 mm of floor length plus safety clearance, which is challenging in shops with limited linear floor space
- Rapid traverse rates of 12–15 m/min are slower than short-bed turning centers, as the carriage must cover longer distances at safe speeds — this is inherent to long-bed machine design, not a Spinner-specific limitation
- Spinner's service network limitations outside Central Europe are a concern for the TL1000's target market, which includes energy and aerospace shops globally where Spinner has fewer regional service engineers

Frequently Asked Questions
01
For long, slender shafts, the TL1000 supports steady rest and follower rest accessories that mount to the machine bed and carriage respectively. A fixed steady rest supports the workpiece midway between spindle and tailstock, while a traveling follower rest moves with the cutting tool to provide continuous support immediately behind the cutting point. This combination allows precision turning of shafts with length-to-diameter ratios that would otherwise cause workpiece deflection and taper errors.
02
The standard TL1000 is a single-spindle machine with a conventional tailstock. Sub-spindle configurations are not standard in the TL1000 product line, which is optimized for long-shaft work requiring tailstock support rather than cut-off and transfer operations. Shops requiring sub-spindle capability for shorter turned parts should consider Spinner's TC series or other turning center platforms.
03
Steady rest configurations for the TL1000 typically support workpieces from 20 mm to 300 mm in diameter, depending on the selected steady rest model. Spinner offers proprietary steady rests sized to the TL1000's bed width. Third-party steady rests (Rohm, SMW-Autoblok) may also be compatible — buyers should confirm mounting interface dimensions with Spinner before ordering.
04
A conventional floor lathe (engine lathe) offers greater swing diameter and often longer between-centers capacity, but lacks the CNC control precision, programmable turret, and rapid traverse of the TL1000. For production turning of shaft families where programs are repeated and process documentation is required, the TL1000's CNC capabilities deliver consistent part-to-part repeatability, reduced operator skill dependency, and automatic cycle execution that a manual floor lathe cannot match. The TL1000 is the right choice when production repeatability and tolerance consistency are more important than occasional very-large-diameter swing.
05
The TL1000 tailstock can support workpieces within the machine's between-centers capacity with total workpiece weight up to approximately 300–400 kg in standard configuration, depending on center height and fixture configuration. For heavier workpieces, the machine foundation, chuck, and steady rest configuration must be assessed to ensure adequate support. Very heavy shafts may require special foundation fixtures or machine customization — Spinner's application engineers should be consulted for workpieces exceeding 300 kg.
