CN-DX50 CNC Turning and Milling Lathe for Long Shafts and Disc Parts
The CN-DX50 CNC turning and milling lathe is designed for manufacturers that need more than ordinary turning. In many B2B machining projects, long shaft parts and large-diameter disc parts often require turning, drilling, milling, side-hole processing, boring, and end-face machining. If these processes are completed on different machines, production becomes slower, clamping errors increase, and labor cost rises.
The CN-DX50 helps solve this problem by supporting turning, drilling, and milling in one clamping. With a side power head structure, Y-axis machining capability, horizontal 6-station turret, and automatic gearbox shifting, this machine provides a flexible machining platform for industrial parts suppliers, job shops, equipment repair factories, and custom CNC machining service providers.
As a heavy duty CNC lathe machine, the CN-DX50 uses an integrated casting machine bed for strength and rigidity. The gearbox and spindle adopt a separated structure, helping reduce the influence of vibration and temperature rise on machining accuracy. This makes the machine suitable for long shafts, disc parts, sleeves, flanges, fittings, and other metal components that require stable cutting and better process integration.
For buyers looking for a practical long shaft CNC lathe, the CN-DX50 provides 1000mm, 1500mm, and 2000mm workpiece length options, with corresponding Z-axis travel and machine sizes to match different production needs.
Key Features
Gearbox Automatic Shifting Structure
The CN-DX50 adopts a gearbox automatic shifting structure. According to the document, one operator can operate 2–4 sets of machines, helping save labor cost and improve production efficiency.
For B2B factories, this is important because machining cost is not only determined by machine price. Operator workload, production rhythm, and machine usability also affect long-term operating cost.
Separated Gearbox and Spindle Structure
The gearbox and spindle use a separated structure. This design helps separate vibration and temperature rise, which can improve machining accuracy and long-term machine stability.
For a CNC turning and milling lathe, reducing vibration is especially important because turning, drilling, and milling may create different cutting forces in one setup.
Integrated Casting Machine Bed
The machine bed adopts integrated casting technology, providing high strength and high rigidity. This structure helps guarantee processing stability during turning and milling operations.
For long shaft parts and disc parts, bed rigidity directly affects dimensional consistency, surface quality, and cutting reliability.
Suitable for One-Clamping Turning, Drilling, and Milling
The CN-DX50 is suitable for long shaft and large-diameter disc parts that need to be clamped once for turning, drilling, and milling. This helps reduce repeated clamping and improves machining consistency.
For custom machining suppliers, this can shorten the production process and reduce the risk of accumulated positioning error.
Side Power Head with Y-Axis Capability
The power head uses ER25 clamping, with a clamping range of Ø1–Ø16mm. Its dynamic form is side three-axis with Y-axis, and the maximum rotating speed reaches 3000r/min.
This configuration allows the machine to support more flexible drilling and milling operations than a basic turning lathe.
6-Station Horizontal Turret
The CN-DX50 uses a horizontal 6-working-station turret. The turret transfer time is 2.8s/3s for every workstation 45°/60° movement.
The 6-station turret supports tool arrangement for turning, boring, drilling, threading, grooving, and other machining operations.
Large Spindle Bore with Optional Upgrade
The standard spindle bore is 82mm, and the optional spindle bore is 122mm. The maximum bar diameter through the spindle hole is 80mm, with an optional 120mm capacity.
This gives the machine better flexibility for larger bar stock, pipe materials, and long cylindrical workpieces.
Three-Gear Automatic Shift Spindle
The spindle uses a three-gear automatic shift gearbox with a speed range of 34–2000r/min:
- High range: 215–2000r/min
- Medium range: 76–700r/min
- Low range: 34–320r/min
This makes the CN-DX50 suitable for different workpiece diameters, materials, and cutting loads.
Benefits for B2B Manufacturing Buyers
Reduced Secondary Processing
The CN-DX50 can complete turning, drilling, and milling in one clamping for suitable parts. This reduces the need to transfer workpieces between multiple machines.
For B2B buyers, fewer setups can help improve accuracy, shorten lead time, reduce labor work, and improve order delivery stability.
Better Efficiency with Multi-Machine Operation
Because the machine uses an automatic shifting structure and practical operating layout, one operator can manage 2–4 sets under suitable production conditions. This helps reduce labor cost in batch production.
Improved Accuracy Through Structure Design
The separated gearbox and spindle structure helps reduce vibration and heat transfer influence, while the integrated casting bed improves rigidity. These design points support more stable machining accuracy.
The document also provides positioning and repeatability data, including X-axis repeat positioning accuracy of 0.006mm and Z-axis repeat positioning accuracy depending on machine length.
Flexible for Long Shaft and Disc Parts
The CN-DX50 supports different workpiece lengths and can process long shaft parts, disc parts, pipe-type parts, and large-diameter components. As a long shaft CNC lathe, it is useful for manufacturers handling mixed part sizes and different customer drawings.
Suitable for Turning and Milling Service Providers
For CNC job shops, the CN-DX50 provides both turning and milling capability in one machine platform. This makes it practical for high-mix orders, repair parts, small-batch production, and industrial components with side-hole or face-milling requirements.

How to Choose the Right CN-DX50 Configuration
Choose by Workpiece Length
Select the 1000mm version for shorter shafts and compact workshop layouts. Choose the 1500mm version for general long-part machining. Choose the 2000mm version when longer shafts, rods, or tube-type components are common in production.
Choose by Spindle Bore Requirement
The standard 82mm spindle bore suits many shaft and bar stock applications. If larger pipe or bar material needs to pass through the spindle, the optional 122mm spindle bore can be considered.
Choose by Process Requirement
If the part only requires turning, a standard flat bed CNC lathe may be enough. If the part requires turning plus drilling, milling, or side-feature machining in one setup, the CN-DX50 is more suitable.
Choose by Production Efficiency
For batch production, the automatic shifting structure and one-operator multi-machine operation potential can help improve production efficiency and reduce labor cost.
