CK50S-F Heavy Duty CNC Lathe Machine for Long Shaft and Metal Parts
The CK50S-F heavy duty CNC lathe machine is built for manufacturers that need stronger turning capacity, longer machining length, and stable processing for medium-to-large metal workpieces. With a maximum swing diameter of 630mm over the lathe and a maximum processing diameter of 500mm, this machine is suitable for larger cylindrical parts that cannot be efficiently handled by smaller CNC lathes.
For B2B production, long shafts, sleeves, rollers, threaded rods, pipe fittings, and industrial repair parts often require a machine with enough bed length, spindle bore, tailstock support, and cutting stability. The CK50S-F provides multiple workpiece length options, including 1000mm, 1500mm, 2000mm, and 3000mm, allowing buyers to choose the right configuration according to their product range and workshop layout.
As a CNC turning lathe, the CK50S-F supports general turning processes such as external turning, internal boring, end facing, grooving, threading, and shaft machining. Its 86mm spindle bore and 84mm bar diameter capacity improve flexibility for bar-type materials and tubular workpieces. For factories looking for a practical flat bed CNC lathe, this model offers a balance between machining size, structure simplicity, and daily production usability.
Key Features
630mm Maximum Swing Diameter
The CK50S-F supports a maximum swing diameter of 630mm over the lathe. This gives the machine enough clearance for larger round parts, flanges, discs, sleeves, and industrial components.
For buyers that need to process larger workpieces than a compact CNC lathe can handle, this heavy duty CNC lathe machine provides more machining space and better application coverage.
500mm Maximum Processing Diameter
The maximum processing diameter over the lathe is 500mm, while the maximum processing diameter on the sliding plate is 320mm. This makes the machine suitable for a wide range of turning applications, from medium-sized shaft parts to larger cylindrical components.
Multiple Workpiece Length Options
The CK50S-F is available in four workpiece length versions:
- 1000mm
- 1500mm
- 2000mm
- 3000mm
This gives B2B buyers flexibility when choosing the right machine for short, medium, or long workpieces. For shaft manufacturers and repair workshops, the 2000mm and 3000mm versions are especially useful for longer components.
86mm Spindle Bore
The spindle bore diameter is 86mm, and the bar diameter capacity is 84mm. This allows larger bar stock, pipe materials, and long cylindrical workpieces to pass through the spindle.
For a CNC turning lathe, a larger spindle bore is important because it increases material compatibility and makes the machine more practical for job shops handling different workpiece sizes.
Three-Range Spindle Speed
The CK50S-F uses three spindle speed ranges:
- High range: 500–1600 r/min
- Medium range: 190–760 r/min
- Low range: 45–220 r/min
This allows operators to select suitable spindle speeds for different workpiece diameters, materials, and machining processes. Lower speed ranges are useful for larger parts and heavier cuts, while higher speed ranges are suitable for smaller diameters and finishing operations.
4 or 6 Station Turret Options
The machine supports 4-station or 6-station turret configurations. This gives buyers flexibility depending on machining complexity and tool arrangement needs.
For simple turning, threading, grooving, and boring operations, a 4-station turret may be sufficient. For parts requiring more machining steps, the 6-station turret offers better process flexibility.
MT5 Tailstock Support
The tailstock quill uses MT5 taper and supports a maximum stroke of 150mm. The tailstock also supports ±15mm transverse movement.
This is important for long shaft machining because tailstock support helps improve workpiece stability during turning, especially when machining longer or heavier parts.
Servo Motor Drive
The machine uses a 7.5/11kW spindle servo motor, with 1.5kW longitudinal Z-axis servo motor power and 1.2kW lateral X-axis servo motor power. This provides suitable drive support for general heavy-duty turning operations.
Benefits for B2B Manufacturing Buyers
Suitable for Longer Workpieces
The CK50S-F is suitable for long shafts, rods, rollers, threaded bars, and tubular components. With maximum workpiece length options up to 3000mm, it can meet the needs of factories processing longer parts.
For B2B buyers, this reduces the need to outsource long-part machining and helps improve production control.
Wider Machining Range Than Smaller CNC Lathes
Compared with smaller flat bed lathes, the CK50S-F offers a larger swing diameter, larger spindle bore, and longer machine bed options. This makes it suitable for a broader range of industrial parts.
For workshops that handle different customer drawings, this flat bed CNC lathe provides better flexibility.
Practical for Industrial Turning Applications
The CK50S-F is not designed only for one specific product type. It can be used for shafts, sleeves, fittings, flanges, rollers, pipe parts, repair components, and general metalworking tasks.
This makes it suitable for job shops, equipment maintenance suppliers, machinery parts factories, and industrial component manufacturers.
Flexible Turret Configuration
The option of 4 or 6 turret stations allows buyers to match the machine configuration to their machining process. A 4-station turret is practical for basic turning work, while a 6-station turret supports more tool combinations and more complex parts.
Better Support for Bar and Pipe Materials
With an 86mm spindle bore and 84mm bar capacity, the CK50S-F can handle larger bar stock and pipe-type materials. This improves production flexibility for parts that need through-spindle material feeding or extended bar support.
