B0205-V CNC Precision Automatic Lathe for Small Bar Stock Machining
The B0205-V CNC precision automatic lathe is designed for manufacturers that need stable and efficient machining of small precision parts from bar stock. With a working bar stock diameter range of Ø3–Ø12mm, it is especially suitable for high-volume production of compact components where dimensional consistency, surface quality, cycle time, and tool stability are important.
In small-part manufacturing, machining difficulty often comes from the details. Thin shafts, tiny holes, small threads, connector pins, sleeves, miniature fittings, and medical or electronic components require strong clamping, stable spindle control, accurate tool movement, and reliable secondary machining. The B0205-V is developed to meet these needs with improved tool holder rigidity, stronger spindle clamping force, a reinforced secondary spindle side, and faster X2/Z2 rapid traverse movement.
As a Swiss type CNC lathe for small precision components, the B0205-V supports main spindle machining, back spindle machining, drilling, tapping, cross drilling, cross tapping, and optional rear drive configurations. For factories looking for a compact bar stock CNC lathe, it provides a practical balance between productivity, flexibility, and floor-space efficiency.
Key Features
Optimized Tool Holder Structure
The tool holder structure of the B0205-V has been further optimized, increasing rigidity by more than 20%. This is important for small precision parts because tool vibration can directly affect surface finish, dimensional tolerance, thread quality, and tool life.
A more rigid tool holder helps improve machining stability during turning, drilling, tapping, and cross machining. For batch production, this means more consistent part quality and fewer machining interruptions.
Improved Spindle Clamping Force
The machine features improved spindle clamping force to better support heavy cutting within small-part machining applications. Stronger clamping helps stabilize bar stock during machining and reduces the risk of workpiece movement.
For manufacturers producing precision shafts, pins, sleeves, threaded parts, and small metal fittings, stable clamping is essential for maintaining reliable part accuracy.
Strengthened Secondary Spindle Side
The structure on the secondary spindle side has been strengthened to improve tool life and machining reliability. The screw rod is thickened to 25mm, giving better support during back-side machining and secondary operations.
This feature is useful for parts that require both front-side and back-side processing in one machine cycle, helping reduce manual transfer and improve production consistency.
Faster X2 and Z2 Rapid Traverse
The X2 and Z2 axis rapid traverse speeds are increased to 36 m/min. Faster rapid movement helps reduce non-cutting time and improve cycle efficiency, especially in high-volume small-part production.
For B2B machining suppliers, shorter cycle time can help improve delivery capability and reduce unit production cost.
High-Speed Main and Back Spindle
The main spindle speed range is 200–10,000 r/min, while the back spindle reaches 200–12,000 r/min. This spindle performance supports efficient turning, drilling, tapping, and secondary machining of small-diameter parts.
High-speed spindle capability is especially useful for small bar stock because smaller diameters often require higher rotation speed to maintain proper cutting conditions.
Flexible Guide Bushing Options
The B0205-V supports multiple guide bushing configurations to match different part lengths and machining requirements:
- Guide bushless device: 45mm
- Rotary guide bushing device: 80mm package configuration / 135mm quick matching
- Electric guide bushing device: 170mm optional
- Stationary guide bushing device: 210mm optional
This flexibility allows buyers to choose the right setup based on part geometry, material behavior, length-to-diameter ratio, and production needs.
Benefits for B2B Manufacturing Buyers
Higher Efficiency for Small Precision Parts
The B0205-V is suitable for continuous machining of Ø3–Ø12mm bar stock. With fast spindle speeds, back spindle capability, cross machining options, and improved axis rapid traverse, it helps manufacturers improve output in batch production.
For suppliers handling repeated orders of small components, this CNC precision automatic lathe can help shorten cycle time while maintaining stable machining quality.
Better Stability for Tight-Tolerance Components
Small parts often require higher stability because even minor vibration or clamping movement may cause visible defects or tolerance deviation. The B0205-V improves stability through optimized tool holder rigidity, enhanced spindle clamping, and a strengthened secondary spindle structure.
This makes it suitable for components used in electronics, medical equipment, automotive assemblies, precision instruments, and custom hardware applications.
Reduced Secondary Processing
With main spindle, back spindle, drilling, tapping, cross drilling, and optional rear drive capability, the machine can complete more processes in one setup. This reduces the need to move parts between different machines.
For B2B buyers, fewer secondary operations can help reduce labor cost, improve accuracy, and simplify production management.
Compact Footprint for Production Lines
The machine size is 2,015 × 1,175 × 1,730mm, making it suitable for workshops that need high productivity but limited floor space. Its compact design helps factories arrange multiple machines more efficiently and expand capacity with better space utilization.
Flexible for Different Part Types
With a total tool storage capacity of 21 and optional cross machining configurations, the B0205-V Swiss type CNC lathe can support different part structures, including shafts, pins, sleeves, screws, connectors, terminals, miniature fasteners, and precision fittings.
