B0206TF-III Swiss Type CNC Lathe for Complex Small Parts Machining
The B0206TF-III Swiss type CNC lathe is built for manufacturers that need efficient turning, drilling, tapping, milling, and back-side machining of small precision parts. With a Ø3–Ø20mm working bar stock diameter range, this machine is suitable for compact metal components that require tight dimensional control, high spindle speed, stable clamping, and multi-process machining in one cycle.
For B2B precision machining suppliers, small parts often create big production challenges. A part may require front turning, back-side drilling, off-center holes, cross tapping, slotting, or end milling. If these processes require several machines, the result is longer cycle time, more manual handling, and higher risk of positioning error. The B0206TF-III helps solve this issue by combining 6-axis control, main and back spindle machining, optional power tools, and Y2-axis back tool post capability.
As a CNC automatic lathe, the B0206TF-III is suitable for continuous bar-fed production of precision parts used in electronics, medical devices, automotive systems, instrumentation, hardware, connectors, and custom CNC machining services. Its compact machine body also makes it practical for workshops that need higher output without using excessive floor space.
Key Features
6-Axis Control for Flexible Machining
The B0206TF-III uses 6 controlled linear axes, supporting more flexible tool movement and process combination. This allows the machine to handle small components with more complex geometries than basic turning machines.
For parts that require multiple surfaces, radial holes, back-side features, and off-center machining, 6-axis control helps improve production efficiency and reduce secondary setups.
Y2-Axis Back Tool Post for Back-Side Machining
One of the key advantages of this Swiss type CNC lathe is the Y2-axis on the back tool post. With this configuration, the machine can support simultaneous back-side machining such as:
- Off-center drilling
- Off-center tapping
- End milling
- Cross drilling on the back side
This is especially useful for precision parts that require more than simple turning. It helps manufacturers complete more features in one machining cycle and reduce transfer between machines.
Ø3–Ø20mm Bar Stock Capacity
The B0206TF-III supports Ø3–Ø20mm working bar stock diameter. This range makes it suitable for small shafts, connector pins, sleeves, precision fittings, threaded parts, terminals, small fasteners, and miniature metal components.
For factories producing small-diameter parts in batches, this precision bar turning machine provides a practical solution for stable and repeatable machining.
High-Speed Main and Back Spindles
The main spindle speed range is 200–10,000 min⁻¹, while the back spindle speed range is 200–12,000 min⁻¹. These spindle speeds support efficient cutting conditions for small-diameter materials.
The machine also supports main spindle drilling up to Ø10mm and tapping up to M10, while the back spindle supports chucking up to Ø20mm, drilling up to Ø8mm, and tapping up to M8.
25-Tool Storage Capacity
The B0206TF-III provides a total tool storage capacity of 25. This allows manufacturers to combine turning tools, drilling tools, tapping tools, optional cross machining tools, and back-side tools for more complete part processing.
For high-mix production, more tool capacity helps reduce tool change limitations and makes the machine more adaptable to different part designs.
Optional Cross Drilling, Cross Tapping, and Slotting
The machine supports optional cross drilling up to Ø6mm and cross tapping up to M5 × 0.8mm. It also supports an optional tool spindle slotting cutter diameter up to Ø30mm, back drilling up to Ø6mm, and back tapping up to M5.
These options make the B0206TF-III suitable for complex precision parts that require radial features, side holes, slots, and back-side threaded holes.
Benefits for B2B Manufacturing Buyers
Complete More Processes in One Machine
The biggest value of the B0206TF-III is process integration. With turning, drilling, tapping, cross machining, and back-side machining capability, manufacturers can reduce secondary operations and improve part consistency.
For B2B buyers, fewer setups mean shorter lead times, lower labor dependency, and less risk of accumulated positioning error.
Better Efficiency for Batch Small Parts
The machine is designed for continuous small-part production from bar stock. With high-speed spindles, 25-tool capacity, 6-axis control, and optional power tools, this CNC automatic lathe supports efficient production of repeated precision components.
It is suitable for suppliers that need to handle frequent orders of small metal parts while maintaining stable production rhythm.
Suitable for Complex Precision Components
Many small parts require side holes, back-side holes, slots, threads, or off-center features. The B0206TF-III can support these machining needs through the Y2-axis back tool post and optional cross machining devices.
This makes it more suitable than a basic turning machine when the part structure is complex.
Compact Footprint for Workshop Capacity Planning
The machine size is 2,125 × 1,135 × 1,700mm, with a net weight of 1,900kg. Its compact footprint makes it suitable for factories that need to add machining capacity without occupying too much floor space.
For workshops running multiple machines, compact layout can improve production planning and machine density.
Flexible Guide Bushing Choices
The B0206TF-III supports multiple guide bushing options, including stationary guide, rotary guide bushing, electrical direct driving guide bush, and guide bushless configurations. This gives buyers more flexibility depending on part length, material condition, and machining stability requirements.
