B0266A-III Swiss Type CNC Lathe for Ø8–Ø26mm Precision Parts
The B0266A-III Swiss type CNC lathe is designed for manufacturers that need stable, efficient, and flexible machining of Ø8–Ø26mm bar stock components. Compared with smaller automatic lathes, this model provides stronger machining capacity, more tool storage, and 6-axis control, making it suitable for complex-shaped workpieces that require turning, drilling, tapping, deep drilling, slotting, and back-side machining in one production process.
For B2B precision machining suppliers, medium-diameter parts often bring more production challenges than simple small shafts or pins. A single component may require front-end turning, back-side drilling, internal tapping, side-feature machining, slotting, or long-part support. If these operations are processed on several machines, production time increases, labor cost rises, and part accuracy may be affected by repeated clamping.
The B0266A-III helps solve these issues by combining a CNC precision automatic lathe platform with high-speed main and back spindle machining, 36-tool storage capacity, flexible guide bushing options, and front/rear/back tool post machining functions. As a sliding headstock CNC lathe, it is suitable for both batch production and high-mix custom CNC turning applications.
Key Features
6-Axis Control for Complex Workpieces
The B0266A-III uses a 6-axis controlled structure, allowing more flexible tool movement and process arrangement than basic automatic turning machines. This helps manufacturers complete more machining features in one setup, including turning, drilling, tapping, back-side machining, and tool spindle operations.
For complex-shaped workpieces, 6-axis control can reduce secondary operations and improve dimensional consistency.
Ø8–Ø26mm Bar Stock Capacity
The machine supports a working bar stock diameter range of Ø8–Ø26mm and a maximum back spindle chucking diameter of Ø26mm. This makes it suitable for medium-diameter precision components such as shafts, sleeves, fittings, bushings, hydraulic parts, connectors, and custom turned metal parts.
For buyers upgrading from smaller Swiss-type machines, the B0266A-III provides more capacity while keeping the advantages of automatic bar-fed production.
36-Tool Storage Capacity
One major advantage of the B0266A-III is its 36-tool storage capacity. More tool positions allow manufacturers to arrange turning tools, drilling tools, tapping tools, slotting tools, and optional rear or back tool post tools for complex machining programs.
For high-mix production, 36 tools give the Swiss type CNC lathe better flexibility when handling different customer drawings and part requirements.
High-Speed Main and Back Spindles
The main spindle and back spindle both support 200–10,000 r/min operation, with rated speed at 7,000 r/min. The main spindle and back spindle motors are both rated at 3.7/5.5kW, giving the machine stable cutting support for Ø26mm-class precision parts.
The main spindle supports drilling up to Ø14mm and tapping up to M14, while the back spindle supports drilling up to Ø13mm and tapping up to M12. This makes the machine suitable for parts that require stronger hole-making and thread machining capability.
Flexible Guide Bushing Options
The B0266A-III supports multiple guide bushing configurations:
- Electrical direct driving guide bush: up to 320mm machining length
- Rotary guide bushing: up to 90mm machining length
- Guide bushless configuration: up to 70mm machining length
These options allow buyers to select the most suitable setup based on part length, material stability, accuracy requirements, and production method.
Tool Spindle Drilling, Tapping, and Slotting
The B0266A-III supports tool spindle machining from front, rear, and back tool post configurations. It supports front tool post drilling up to Ø8mm, rear/back tool post drilling up to Ø10mm, front tool post tapping up to M6, and rear/back tool post tapping up to M8.
The machine also supports a maximum tool spindle slotting cutter diameter of Ø45mm on the front tool post, making it useful for components that require slots, grooves, and special side features.
Deep Drilling Capability
The maximum spindle deep drilling diameter reaches Ø10mm. For parts such as shafts, fittings, hydraulic components, and instrument parts, deep drilling capability can help complete more demanding internal features within the same machine cycle.
Benefits for B2B Manufacturing Buyers
More Complete Machining in One Setup
The B0266A-III can combine turning, drilling, tapping, deep drilling, slotting, and back-side machining in one machine. This helps reduce manual transfer, secondary clamping, and process interruption.
For B2B manufacturers, fewer setups usually mean shorter lead times, better repeatability, and lower labor dependency.
Better Flexibility for High-Mix Orders
Custom CNC machining suppliers often need to handle many different part drawings. Some parts may require only turning and drilling, while others may require rear-side tapping, cross features, slotting, or longer guide bushing support.
With 36-tool capacity and flexible guide bushing options, the B0266A-III CNC precision automatic lathe can adapt to different part structures more easily.
Stable Accuracy for Medium-Diameter Precision Parts
The document highlights that optional guide bushing use supports high-speed and high-precision processing, stable operation, and improved shape accuracy, dimensional accuracy, and surface finish. This is important for parts used in automotive, medical, electronics, hydraulic, and instrumentation applications.
For manufacturers supplying assembly-critical components, stable dimensional control helps reduce rework and improve customer acceptance.
Stronger Capability Than Smaller Swiss-Type Machines
Compared with machines designed for Ø12mm or Ø20mm parts, the B0266A-III supports Ø26mm bar stock and stronger drilling/tapping capacity. It is suitable for manufacturers that need more machining range while still maintaining compact automatic lathe productivity.
Compact Production Footprint
With a machine size of 2,630 × 1,695 × 1,970mm and a net weight of 3,700kg, the B0266A-III provides strong machining capability without requiring excessive workshop space. This makes it practical for production lines where multiple machines need to be arranged efficiently.
