B0385L-III Swiss Type CNC Lathe for Ø8–Ø38mm Bar Stock Parts
The B0385L-III Swiss type CNC lathe is designed for manufacturers that need stable machining of larger precision bar stock components. With a working bar stock diameter range of Ø8–Ø38mm and a maximum back spindle chucking diameter of Ø38mm, this model is suitable for medium-to-large turned parts that require stronger spindle power, higher process flexibility, and reliable production consistency.
Unlike smaller Swiss-type machines that mainly focus on miniature parts, the B0385L-III is built for heavier precision turning applications. It supports turning, drilling, tapping, deep drilling, slotting, back-side machining, and tool spindle machining within one compact platform. For B2B machining suppliers, this helps reduce secondary clamping, shorten production flow, and improve part consistency.
The machine also uses a special guide bushless CNC lathe configuration with a maximum machining length of 100mm. This makes it suitable for shorter bar stock parts where guide-bushing support is not required, helping reduce material friction and simplify machining for suitable part structures.
As a CNC precision automatic lathe, the B0385L-III is suitable for variable production of complex-shaped workpieces, especially for factories serving automotive, hydraulic, medical, industrial hardware, fastener, and custom CNC turning markets.
Key Features
Ø8–Ø38mm Bar Stock Machining Capacity
The B0385L-III supports Ø8–Ø38mm working bar stock diameter, giving manufacturers more capacity than smaller Swiss-type lathe models. It can process larger shafts, sleeves, bushings, fittings, hydraulic connectors, valve parts, fasteners, and industrial turned components.
For buyers that need one machine to cover a wider part range, this Swiss type CNC lathe provides strong flexibility for Ø38mm-class production.
Guide Bush-Less-Kit Structure
The B0385L-III is configured with a special guide bush-less-kit, supporting a maximum machining length of 100mm. This structure is suitable for shorter parts where guide bushing support is not necessary.
For suitable components, a guide bushless CNC lathe can help reduce setup complexity and improve production practicality. It is especially useful for short shafts, sleeves, fittings, bushings, and precision parts with stable bar material conditions.
Strong Main Spindle Power
The main spindle motor power reaches 7.5/11kW, providing stronger cutting support for Ø38mm bar stock parts. Higher spindle power is important when machining larger-diameter materials, tougher metals, or parts requiring more stable cutting force.
The back spindle motor power is 3.7/5.5kW, supporting back-side drilling, tapping, and finishing operations after main spindle machining.
5-Axis Controlled Structure
The B0385L-III uses a 5-axis controlled structure. This allows more flexible tool movement and supports multi-process machining in one machine cycle.
For complex-shaped workpieces, 5-axis control helps reduce manual transfer between machines and improves machining consistency. This is valuable for B2B suppliers handling custom drawings and high-mix production.
31-Tool Storage Capacity
The machine provides 31 tool positions, allowing operators to arrange turning tools, drilling tools, tapping tools, slotting tools, front tool post tools, rear tool post tools, and back tool post options.
For complex precision parts, more tool capacity means better process planning and fewer limitations during machining.
Main and Back Spindle Machining Capability
The main spindle speed range is 200–6,000 r/min, while the back spindle reaches 200–7,000 r/min. The main spindle supports drilling up to Ø13mm and tapping up to M12. The back spindle supports drilling up to Ø12mm and tapping up to M12.
This allows the B0385L-III CNC precision automatic lathe to complete front-side and back-side machining more efficiently in one production flow.
Slotting and Tool Spindle Machining
The B0385L-III supports tool spindle drilling up to Ø10mm and tool spindle tapping up to M8 from front, rear, or back tool post configurations. The maximum tool spindle slotting cutter diameter reaches Ø45mm on the front tool post.
This expands the machine’s ability to process grooves, side features, slots, radial holes, and more complex part structures.
Benefits for B2B Manufacturing Buyers
Larger Capacity for Ø38mm Precision Components
The B0385L-III is suitable for manufacturers that need to process larger bar stock parts while maintaining the advantages of Swiss-type automatic machining. Its Ø38mm bar capacity and Ø43.6mm main spindle hole diameter provide stronger flexibility for medium-to-large precision components.
Better Process Integration
This Swiss type CNC lathe can combine turning, drilling, tapping, slotting, deep drilling, and back-side machining in one machine platform. This helps reduce secondary processing and improves production consistency.
For B2B buyers, fewer setups often mean shorter lead times, lower labor dependency, and reduced risk of accumulated positioning error.
Suitable for Short-Part Guide Bushless Machining
The special guide bush-less-kit makes the B0385L-III suitable for shorter precision parts with a maximum machining length of 100mm. For suitable workpieces, this guide bushless CNC lathe configuration can simplify production and reduce the need for guide bushing support.
Stronger Cutting Support for Industrial Parts
With 7.5/11kW main spindle power, the B0385L-III can support larger bar stock and more demanding cutting conditions than smaller automatic lathes. This is useful for hydraulic fittings, steel shafts, valve components, industrial sleeves, and precision hardware.
Flexible for High-Mix Custom Turning
The 31-tool capacity and 5-axis structure make the machine suitable for custom CNC machining suppliers. It can handle different drawings, part geometries, materials, and order volumes with better process flexibility.
