The Used Mori Seiki SL-253 CNC lathe (2001) is a twin spindle CNC turning machine manufactured in 2001. It is equipped with Mori Seiki MSG-501 control, a main spindle, sub spindle, 12-station live tooling turret and swarf conveyor. This configuration makes the machine suitable for flexible turning work, back-working operations and components that require additional drilling, milling or threading operations on the lathe.
With a maximum turning diameter of 390 mm, maximum turning length of 485 mm and swing over bed of 680 mm, the Mori Seiki SL-253 offers practical capacity for small to medium-sized turned components. The main spindle reaches 3,500 rpm, while the sub spindle reaches up to 6,000 rpm. The spindle bore of 75 mm is a useful specification for buyers working with bar material or components with larger diameters.
The machine is fitted with a 250 mm main chuck and a 170 mm sub chuck. The 12-station turret includes live tooling, with live tool speed up to 3,000 rpm. This allows the machine to perform not only standard turning operations, but also additional machining tasks depending on the tooling, workholding and programme set-up. For production environments, this type of machine can help reduce secondary operations when the part geometry is suitable.

This Mori Seiki SL-253 is equipped with Mori Seiki MSG-501 control. Mori Seiki machines are widely recognised in CNC turning, especially in production machining and industrial metalworking. For workshops already familiar with Mori Seiki turning machines, the control and machine layout may be a practical advantage.
The included equipment consists of main spindle, sub spindle, 12-station turret with live tooling, 250 mm main chuck, 170 mm sub chuck and swarf conveyor. The sub spindle is useful for machining the second side of a component without removing it from the machine. This can reduce additional handling and can be especially relevant for production parts that need front and back machining.
The live tooling turret extends the capability of the machine beyond standard turning. Depending on the available driven tool holders and tooling package, the machine can be used for drilling, milling, cross-hole machining and threading operations directly in the lathe. The live tool speed of 3,000 rpm provides a useful basis for these additional operations, depending on material, tool diameter and cutting data.
The swarf conveyor supports chip removal during longer machining cycles and helps keep the working area clearer. Further details regarding current machine condition, working hours, spindle hours, maintenance history, C-axis specification, tool holders, manuals, location or inspection under power have not been provided and should be requested before purchase.
The Used Mori Seiki SL-253 CNC lathe is suitable for a wide range of CNC turning applications in industrial production. Typical workpieces include shafts, bushes, flanges, pins, rings, threaded parts, hydraulic components, pneumatic components and other rotational parts. With a 390 mm maximum turning diameter and 485 mm turning length, the machine covers many common small and medium-sized turning jobs.
The twin spindle configuration is particularly useful for components requiring machining on both sides. The part can be transferred to the sub spindle for back-working, which can help reduce separate second-operation machining when the part is suitable. This makes the machine relevant for subcontract machining, batch production, automotive supply, mechanical engineering and general precision turning.
The live tooling capability gives additional flexibility. Instead of moving the workpiece to a separate milling machine for simple holes, flats or minor milling operations, these features may be machined directly on the turning machine. This can be useful for parts with cross holes, bolt patterns, milled surfaces or threaded holes, depending on the exact tooling and machine configuration.
For buyers searching for a compact CNC lathe with sub spindle and live tooling, this Mori Seiki SL-253 offers a practical specification for flexible turning work. It can be used in workshops that produce single parts, small batches or recurring production components.
For similar used turning machines, you can also browse our Lathe-Machine, Dual-spindle-Lathe-Machine and Face-Lathe-Machine categories, where you will find further machines for CNC turning, facing, shaft machining and production work. Depending on the application, machines from the Vertical-Lathe-Machine or Manual-Lathe-Machine categories may also be relevant for larger workpieces, repair machining or conventional workshop tasks.
This Used Mori Seiki SL-253 CNC lathe offers a useful combination of twin spindle machining, live tooling, compact turning capacity and Mori Seiki MSG-501 control. It is especially relevant for buyers who need a used CNC turning machine that can perform more than basic turning operations.
The sub spindle is one of the key advantages of this machine. It allows second-side machining and can support more complete part production in one machine cycle, depending on the component. The 12-station live tooling turret also increases flexibility by allowing selected milling, drilling and threading operations directly on the lathe. These features can be valuable for workshops handling varied turning work or production parts with additional machining requirements.
The Used Mori Seiki SL-253 CNC lathe is also equipped with a swarf conveyor, 75 mm spindle bore, 15 kW spindle motor and chucks on both main and sub spindle. These specifications make it a practical option for companies looking for a used twin spindle CNC lathe for industrial metalworking. As with every used machine tool, the spindle condition, turret, live tooling function, axes, control system and geometry should be checked carefully before purchase.
