B0265-III CNC Precision Automatic Lathe for Ø8–Ø26mm Bar Stock
The B0265-III CNC precision automatic lathe is built for manufacturers that need stable, efficient, and flexible machining of medium-diameter precision components. With a working bar stock diameter range of Ø8–Ø26mm, this machine is suitable for parts that require higher rigidity than micro-part machining, while still demanding the speed and process integration of a compact automatic lathe.
In real production, Ø26mm-class precision parts often require more than simple turning. A single component may include front drilling, back drilling, tapping, deep holes, side features, slotting, and secondary finishing. If these operations are separated across multiple machines, production becomes slower, labor cost increases, and accumulated positioning errors may affect final quality. The B0265-III helps solve these problems by combining main spindle machining, back spindle machining, tool spindle processing, optional guide bushing configurations, and 32-tool capacity in one machine platform.
As a Swiss type CNC lathe and sliding headstock CNC lathe, the B0265-III is suitable for high-mix and batch production of complex-shaped workpieces. The optional guide bushing structure supports high-speed and high-precision processing, helping improve shape accuracy, dimensional accuracy, and surface finish for precision components.
Key Features
Ø8–Ø26mm Bar Stock Machining Capacity
The B0265-III supports a working bar stock diameter from Ø8mm to Ø26mm. This range makes it suitable for medium-diameter precision parts such as shafts, sleeves, fittings, connectors, valves, fasteners, and custom turned components.
For manufacturers that need more machining capacity than smaller Ø12mm or Ø20mm machines, the B0265-III provides a practical upgrade while keeping the advantages of automatic bar-fed production.
Flexible Machining Length Options
The machine supports different machining lengths depending on the selected guide bushing configuration:
- 320mm with electrical direct driving guide bush
- 90mm with rotary guide bushing
- 70mm with guide bushless configuration
This gives buyers flexibility when processing short parts, long slender components, or parts that require better material support during machining.
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. This spindle performance supports efficient turning, drilling, tapping, and secondary machining for medium-diameter bar stock.
The main spindle motor and back spindle motor are both rated at 3.7/5.5kW, providing stronger machining support for components that require higher cutting stability.
5-Axis Controlled Structure
The B0265-III uses a 5-axis controlled structure, making it suitable for more complex workpieces than basic automatic lathes. This helps support flexible tool movement and multi-process machining on small and medium precision parts.
For B2B buyers producing complex-shaped parts, a 5-axis sliding headstock CNC lathe can help reduce secondary setups and improve process consistency.
32-Tool Storage Capacity
The machine provides a total tool storage capacity of 32. This allows manufacturers to combine turning tools, drilling tools, tapping tools, slotting tools, and optional rear tool post or back tool post configurations.
More tool capacity is especially useful for high-mix production, where different customer drawings may require different machining processes.
Strong Drilling and Tapping Capacity
The B0265-III supports:
- Max. main spindle drilling diameter: Ø14mm
- Max. main spindle tapping diameter: M14
- Max. back spindle drilling diameter: Ø13mm
- Max. back spindle tapping diameter: M12
- Max. spindle deep drilling diameter: Ø10mm
These specifications make the machine suitable for parts that require deeper holes, larger threads, and more complete machining within one cycle.
Tool Spindle and Slotting Capability
The machine supports tool spindle drilling and tapping from front, rear, or back tool post configurations depending on options. It also supports a maximum tool spindle slotting cutter diameter of Ø45mm on the front tool post.
This expands machining possibilities for parts with grooves, slots, side holes, and special geometric features.
Benefits for B2B Manufacturing Buyers
More Complete Machining in One Setup
The B0265-III helps manufacturers complete turning, drilling, tapping, deep drilling, slotting, and back-side machining in one machine. This reduces the need for secondary machines and manual part transfer.
For B2B suppliers, fewer setups can help improve dimensional consistency, shorten delivery time, and reduce labor dependency.
Better Accuracy for Complex-Shaped Workpieces
The document highlights that optional guide bushing use supports high-speed and high-precision processing, improving shape accuracy, dimensional accuracy, and surface finish. This is important for precision parts used in automotive, medical, hydraulic, electronic, and industrial assemblies.
As a CNC precision automatic lathe, the B0265-III is suitable for parts where small dimensional variation can affect assembly performance.
Higher Productivity for Medium-Diameter Parts
With 32-tool capacity, 35 m/min rapid traverse rate, high-speed spindles, and flexible machining configurations, the B0265-III supports efficient production for Ø8–Ø26mm parts.
For manufacturers handling batch orders, these features can help improve production rhythm and reduce idle time.
Suitable for High-Mix Custom CNC Turning
Different customer parts often require different combinations of turning, drilling, tapping, slotting, and back machining. The B0265-III offers flexible tooling and guide bushing options, making it suitable for custom CNC machining suppliers serving multiple industries.
Compact but Strong Production Capability
With a machine size of 2,630 × 1,695 × 1,970mm and net weight of 3,700kg, the B0265-III provides stronger machining capacity while maintaining a workshop-friendly footprint. It is suitable for factories that need to increase capacity without moving to large horizontal or conventional turning centers.
