CK80S Heavy Duty CNC Lathe Machine for Large Shaft and Industrial Parts
The CK80S heavy duty CNC lathe machine is designed for manufacturers that need larger swing capacity, stronger rigidity, and stable machining performance for medium-to-large metal workpieces. With a maximum swing diameter of 800mm over the lathe and a maximum workpiece length available in 1000mm, 1500mm, 2000mm, and 3500mm versions, this machine is suitable for large shaft parts, sleeves, rollers, pipe components, flanges, discs, and general industrial turning applications.
For B2B buyers, large workpieces usually require more than simple diameter capacity. The machine must have enough bed rigidity, guide rail span, spindle torque, tailstock support, and stable feed movement to handle cutting impact during heavy or interrupted machining. The CK80S is built for this type of production environment, with a 510mm guide span, 400mm center height, 11kW main motor, and geared headstock structure.
As a large swing CNC lathe, the CK80S can be used to process cylindrical surfaces, round parts, end faces, cones, arbitrary conic cylindrical surfaces, drilling, and reaming. Its manual three-gear spindle speed system provides high, medium, and low speed ranges, allowing operators to select suitable cutting conditions for different materials and workpiece diameters.
For factories looking for a practical flat bed CNC lathe, the CK80S offers a strong balance of machining size, structural rigidity, torque support, and daily production usability.
Key Features
800mm Maximum Swing Over Lathe
The CK80S supports a maximum swing diameter of 800mm over the lathe. This makes it suitable for large round components, flanges, discs, sleeves, rollers, and heavy-duty cylindrical parts.
For manufacturers processing parts that exceed the capacity of smaller CK50 or CK56 class machines, this heavy duty CNC lathe machine provides a larger working envelope for industrial turning.
Up to 3500mm Workpiece Length
The machine is available in four workpiece length versions:
- 1000mm
- 1500mm
- 2000mm
- 3500mm
The corresponding maximum machining lengths are 900mm, 1400mm, 1900mm, and 3400mm. This gives buyers flexibility to choose the proper machine length based on shaft length, workshop space, and actual production needs.
400mm Center Height and 510mm Guide Span
The CK80S has a 400mm center height and 510mm guide span. These specifications support larger workpiece clearance and better structural stability during machining.
For a large swing CNC lathe, guide span is important because it affects bed support, cutting stability, and long-term machining consistency.
550mm Workpiece Diameter on Carriage
The maximum workpiece diameter on the carriage is 550mm. This allows the machine to process large components while maintaining enough space for tool movement and machining operations.
This feature is useful for large sleeves, collars, pipe fittings, flanges, rollers, and heavy machinery parts.
Manual Three-Gear Spindle Speed System
The spindle uses a manual three-gear speed system with a total rotating speed range of 50–1000r/min. The speed ranges include:
- High range: 400–1000r/min
- Medium range: 100–400r/min
- Low range: 20–50r/min
The geared headstock structure provides large torque at medium and low speeds. This helps the machine handle larger cutting impact, sudden stops, direction changes, and variable-speed machining conditions.
82mm Spindle Bore with Optional 105mm Bore
The standard spindle bore is 82mm, with an optional 105mm spindle bore available. This gives buyers more flexibility when processing larger bar stock, pipe materials, and long cylindrical components.
For B2B workshops handling different customer drawings, spindle bore size directly affects material compatibility.
4 or 6 Station Turret Options
The CK80S supports 4-station or 6-station turret configurations. Buyers can select the turret according to machining complexity.
A 4-station turret is suitable for general turning, facing, boring, and threading. A 6-station turret provides more tool positions for parts requiring multiple machining steps.
MT5 Tailstock for Long Workpiece Support
The machine uses an MT5 tailstock quill with a 90mm sleeve diameter, 150mm maximum stroke, and ±15mm transverse movement. Tailstock support is important for long shaft machining because it helps reduce vibration and improve cutting stability.
11kW Main Motor Power
The CK80S is equipped with an 11kW main motor. This provides stronger power support for large-diameter parts, heavier cutting loads, and industrial turning applications.
Benefits for B2B Manufacturing Buyers
Suitable for Large-Diameter Industrial Parts
The CK80S is built for workpieces that require larger swing capacity and stronger machine support. With an 800mm swing over lathe and 550mm workpiece diameter on the carriage, it is suitable for large sleeves, rollers, pipe fittings, shafts, flanges, and heavy machinery components.
Better Torque Support for Heavy Cutting
The machine uses a geared headstock with high, medium, and low manual speed ranges. The large transmission ratio helps provide stronger torque at medium and low speeds, which is useful for heavy cutting and larger workpieces.
For B2B manufacturers, stronger torque support can improve machining stability and reduce cutting interruption.
Flexible Length Selection for Different Production Needs
The CK80S offers 1000mm, 1500mm, 2000mm, and 3500mm versions. Buyers can choose the right bed length according to their product range.
This helps factories avoid buying an oversized machine when most workpieces are short, while still offering long-bed options for shaft and roller production.
Practical for Custom CNC Turning
As a flat bed CNC lathe, the CK80S is suitable for job shops and custom machining service providers. It can process different drawings, materials, diameters, and lengths, making it practical for high-mix industrial turning work.
Stable Structure for Long-Term Workshop Use
The document highlights that the machine has high precision, low noise, and good rigidity. For workshops running daily production, these points are important because they affect operator experience, machining stability, and long-term reliability.
