B0326A-III Swiss Type CNC Lathe for Ø8–Ø26mm Precision Machining
The B0326A-III Swiss type CNC lathe is designed for manufacturers that need efficient and stable machining of medium-diameter precision components. With a working bar stock diameter range of Ø8–Ø26mm, this machine is suitable for parts that require turning, drilling, tapping, deep drilling, slotting, back-side machining, and high-precision dimensional control.
For B2B machining suppliers, parts in the Ø26mm range often require stronger process flexibility than smaller automatic lathe parts. A single component may need front-side turning, back-side drilling, internal tapping, groove cutting, deep-hole machining, and secondary finishing. When these operations are completed across multiple machines, production becomes slower, labor cost increases, and repeated clamping may affect final accuracy.
The B0326A-III solves this issue by integrating multiple machining functions into one compact CNC precision automatic lathe platform. With 36-tool storage capacity, 5-axis control, optional guide bushing configurations, and front/rear/back tool post machining capability, this sliding headstock CNC lathe is suitable for both batch production and high-mix custom CNC turning.
Key Features
Ø8–Ø26mm Bar Stock Capacity
The B0326A-III supports Ø8–Ø26mm working bar stock diameter, making it suitable for shafts, sleeves, fittings, connectors, bushings, valve parts, precision fasteners, and custom turned metal components.
For manufacturers that need more machining capacity than smaller Swiss-type machines, this model provides a practical balance between bar stock capacity, precision, and automatic production efficiency.
Ø32mm Back Spindle Chucking Diameter
The maximum back spindle chucking diameter reaches Ø32mm. This gives the machine better flexibility for secondary machining, especially when parts require back-side drilling, tapping, or finishing after main spindle machining.
This feature helps reduce manual handling and supports more complete part machining in one cycle.
36-Tool Storage Capacity
One of the key strengths of the B0326A-III is its 36-tool storage capacity. More tool positions allow manufacturers to arrange turning tools, drilling tools, tapping tools, slotting tools, rear tool post tools, and back tool post tools for complex machining programs.
For custom CNC machining suppliers, 36 tools provide stronger adaptability when handling different customer drawings and part requirements.
5-Axis Controlled Structure
The B0326A-III uses a 5-axis controlled structure. This supports flexible machining movement and allows more complete processing than basic automatic turning machines.
For complex-shaped workpieces, 5-axis control helps reduce secondary operations, improve machining consistency, and support better process integration.
High-Speed Main and Back Spindles
The main spindle and back spindle both support 200–8,000 r/min operation. The main spindle rated speed is 6,000 r/min, while the back spindle rated speed is 7,000 r/min.
Both the main spindle and back spindle use 3.7/5.5kW motor power, supporting stable machining for medium-diameter precision parts.
Flexible Guide Bushing Options
The B0326A-III supports multiple machining length configurations:
- 320mm with electrical direct driving guide bush
- 90mm with rotary guide bushing
- 80mm with guide bushless configuration
These options allow buyers to choose the proper setup based on part length, material rigidity, tolerance requirements, and production efficiency.
Drilling, Tapping, Deep Drilling, and Slotting Capability
The B0326A-III supports main spindle drilling up to Ø14mm and tapping up to M14. The back spindle supports drilling up to Ø13mm and tapping up to M12. The machine also supports spindle deep drilling up to Ø10mm.
For tool spindle machining, 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 maximum tool spindle slotting cutter diameter reaches Ø45mm on the front tool post.
Benefits for B2B Manufacturing Buyers
More Complete Machining in One Setup
The B0326A-III can combine turning, drilling, tapping, deep drilling, slotting, and back-side machining in one machine. This reduces manual transfer between machines and helps improve final part consistency.
For B2B manufacturers, fewer setups usually mean shorter lead times, lower labor dependency, and reduced risk of positioning errors.
Better Flexibility for Complex-Shaped Workpieces
The machine is designed for variable production of complex-shaped workpieces. With 36 tools, 5-axis control, and guide bushing options, the B0326A-III can support different part structures and machining processes.
This makes it suitable for machining suppliers that need to process different customer drawings, materials, and order quantities.
Improved Accuracy and Surface Finish
The document notes that the optional conductive sleeve configuration enables high-speed and high-precision processing, helping improve shape accuracy, dimensional accuracy, and surface finish. This is important for parts used in automotive, hydraulic, medical, electronics, and instrumentation applications.
As a Swiss type CNC lathe, the B0326A-III is suitable for components where machining stability directly affects assembly quality.
Higher Tool Capacity Than Standard 32-Tool Models
Compared with 32-tool configurations, the B0326A-III offers 36-tool storage capacity. This gives manufacturers more room to plan complex operations, reduce tool arrangement limitations, and support multi-process production.
For high-mix production, this difference can improve flexibility and reduce setup adjustment frequency.
Compact but Capable Production Platform
With a machine size of 2,630 × 1,695 × 1,970mm and a net weight of 3,700kg, the B0326A-III provides strong machining capacity while keeping a compact workshop footprint.
For factories planning production line expansion, this CNC precision automatic lathe can help increase capacity without requiring excessive floor space.
