CK56S Heavy Duty CNC Lathe Machine for Long Shaft and Industrial Metal Parts
The CK56S heavy duty CNC lathe machine is built for manufacturers that need stable turning performance, stronger rigidity, and practical machining capacity for medium-to-large metal parts. With a maximum swing diameter of 630mm over the lathe and a maximum machining diameter of 560mm on the bed body, this machine is suitable for a wide range of turning applications, including shafts, sleeves, plate-type parts, threaded components, cones, spherical parts, and general machinery components.
For B2B buyers, choosing a CNC lathe is not only about machine size. In daily production, buyers care more about cutting stability, rigidity, machining consistency, operator convenience, and whether the machine can handle different workpiece lengths. The CK56S answers these needs with a geared spindle headstock, high/medium/low manual transmission ranges, CNC-ground guide rails, 86mm spindle bore, MT5 tailstock support, and multiple machine length configurations.
As a CNC turning lathe, the CK56S supports long workpiece machining with maximum machining length options of 900mm, 1400mm, 1900mm, and 2900mm. For factories that process long shafts, rods, sleeves, threaded parts, pipe-type components, or repair parts, this flat bed CNC lathe provides a practical production platform with good rigidity and stable operation.
Key Features
630mm Maximum Swing Over Lathe
The CK56S supports a maximum swing diameter of 630mm over the lathe. This gives the machine enough clearance for larger cylindrical workpieces, plate-type parts, sleeves, flanges, and industrial components.
For manufacturers processing parts larger than compact CNC lathes can handle, this heavy duty CNC lathe machine provides a wider working range while maintaining a practical flat bed structure.
560mm Maximum Machining Diameter on Bed
The maximum machining diameter on the bed body reaches 560mm, while the maximum machining diameter on the drag plate is 410mm. This makes the CK56S suitable for medium-to-large turning tasks where both diameter capacity and cutting stability are important.
This specification is useful for parts such as large sleeves, bushings, collars, fittings, rollers, and repair components.
Multiple Workpiece Length Options
The CK56S is available with maximum workpiece length options of:
- 1000mm
- 1500mm
- 2000mm
- 3000mm
The corresponding maximum machining lengths are 900mm, 1400mm, 1900mm, and 2900mm. This allows B2B buyers to select the proper machine length based on real production needs instead of overbuying unnecessary bed length.
86mm Spindle Bore and 84mm Bar Capacity
The spindle bore is 86mm, and the bar diameter capacity is 84mm. This gives the machine good flexibility for bar stock, pipe materials, long rods, and shaft-type workpieces.
For a CNC turning lathe, a larger spindle bore is important because it allows more material types and part structures to pass through the spindle, improving workshop flexibility.
Three-Gear Manual Spindle Transmission
The spindle uses high, medium, and low gear manual transmission through the headstock gear structure. The spindle speed ranges are:
- High range: 500–1600 r/min
- Medium range: 190–760 r/min
- Low range: 45–220 r/min
The headstock gears use a large transmission ratio, and the widened gear structure helps increase transmission torque at medium and low speeds. This allows the machine to withstand larger cutting impact during heavy or larger-diameter machining.
CNC-Ground Guide Rail and Rigid Structure
The machine uses CNC-ground guide rails, supporting improved movement accuracy and stable long-term operation. The document also highlights high precision, low noise, good rigidity, and convenient operation.
For industrial turning, guide rail quality and machine rigidity directly affect cutting stability, surface quality, and dimensional consistency.
4-Station Turret
The CK56S is equipped with a 4-station turret, suitable for arranging common turning, threading, grooving, boring, and finishing tools.
For general industrial turning and repair work, a 4-station turret provides a simple and practical tool arrangement method without making operation overly complicated.
MT5 Tailstock Support
The tailstock quill uses MT5 taper, with a maximum quill stroke of 150mm and ±15mm transverse movement. This is important for long shaft machining, where tailstock support helps improve workpiece stability and reduce vibration during cutting.
Benefits for B2B Manufacturing Buyers
Suitable for Long Shaft and Large Metal Parts
The CK56S is suitable for long shafts, rods, rollers, sleeves, threaded bars, pipe-type components, and general industrial parts. With maximum workpiece length up to 3000mm and machining length up to 2900mm, it gives manufacturers more flexibility for long-part production.
For B2B factories, this helps reduce outsourcing and improves control over delivery time and machining quality.
Stronger Torque Support at Medium and Low Speed
The geared spindle structure uses high, medium, and low manual transmission. The large transmission ratio and widened gear structure help increase torque at medium and low speeds.
This is valuable when machining larger workpieces, harder materials, or parts that require heavier cutting.
Practical for Industrial Workshops
The CK56S is suitable for a broad range of workshop applications, including production machining, repair machining, equipment maintenance parts, and custom CNC turning services.
For buyers looking for a practical flat bed CNC lathe, this model offers a useful balance between machining capacity, structure rigidity, and daily usability.
Good Rigidity and Stable Operation
The machine is designed with good rigidity, low noise, high precision, and convenient operation. These points are important for production environments where machines need to run reliably over long working periods.
Stable machine performance helps improve part consistency and reduce unnecessary rework.
Flexible Length Selection
The CK56S offers 1000mm, 1500mm, 2000mm, and 3000mm machine length versions. Buyers can match the machine to their actual part size range, workshop space, and production plan.
This makes investment more controlled and practical for different factory scales.
