Lange Grinding & Machining uses the Okuma LB4000 EXII MY CNC Turning Center to support precision turning, live tooling, milling, drilling, contouring, and Y-axis machining for industrial customers. This machine gives our team the flexibility to complete more complex parts in fewer setups while maintaining the rigidity, repeatability, and dimensional control customers expect.
The Okuma LB4000 EXII MY brings high-precision turning and milling capability together in one thermally stable platform. With live tooling and Y-axis travel, Lange can support parts that require both turned features and milled or drilled features without moving the part between multiple machines whenever the job allows.
For customers, that means reduced handling, improved feature-to-feature accuracy, faster throughput, and stronger support for complex parts such as shafts, flanges, housings, sleeves, adapters, repair components, and multi-operation industrial parts.
Precision CNC Turning with Live Tooling
CNC turning is used when a part requires accurate round features, diameters, shoulders, grooves, threads, bores, faces, or other turned surfaces. Live tooling expands that capability by allowing milling, drilling, and contouring operations to be completed on the same machine platform.
The Okuma LB4000 EXII MY helps Lange support projects that require more than basic turning. Instead of turning a part on one machine and moving it to another machine for milled flats, drilled holes, bolt patterns, slots, or contouring, live tooling can reduce the number of setups needed for many parts.
This is especially valuable for industrial customers that need consistent accuracy between turned and machined features. Reducing setups can help improve alignment, shorten production time, reduce handling risk, and keep the process more controlled from start to finish.

Okuma LB4000 EXII MY CNC Turning Center
The Okuma LB4000 EXII MY gives Lange high-precision turning, milling, and Y-axis capability in one rigid machining platform. Its powerful spindle, box-way construction, thermally stable design, and Okuma OSP control help deliver the repeatability needed for demanding materials, long cycle times, and tight-tolerance work.
With live tooling and full Y-axis capability, the LB4000 EXII MY can support turning, milling, drilling, and contouring operations that may traditionally require multiple machines. This allows Lange to complete more features in one setup when the part design and project requirements allow it.
For customers, this machine strengthens Lange’s ability to deliver consistent, high-quality machining for precision shafts, flanges, housings, round components, and multi-operation parts backed by the grinding and inspection expertise Lange is known for.
Live Tooling and Y-Axis Machining Advantages
Live tooling allows rotating tools to perform milling, drilling, and other machining operations while the part remains held in the turning center. Y-axis capability adds additional off-center machining flexibility, which is useful for parts that need drilled holes, milled flats, slots, pockets, contours, or features that do not fall directly on the centerline.
This combination gives Lange more flexibility when machining complex components. A part that requires turned diameters, drilled holes, milled features, and accurate relationships between multiple surfaces can often be completed with fewer part moves.
For customers, fewer setups can lead to better feature-to-feature accuracy, improved repeatability, shorter lead times, and reduced risk of handling-related variation. This is especially important on high-value parts, repair components, and industrial parts with multiple machining requirements.
What This CNC Turning Center Helps Us Produce
The Okuma LB4000 EXII MY supports a wide range of precision CNC turning and machining needs. It is useful for parts that require accurate round features, tight dimensional control, milled or drilled features, and repeatable machining across multiple operations.
Common project types include:
- Precision shafts
- Flanges
- Housings
- Sleeves
- Adapters
- Round industrial components
- Multi-operation turned parts
- Parts requiring turned and milled features
- Components requiring drilled or tapped hole patterns
- Repair components
- High-value industrial parts
- Components that require machining before or after grinding
This equipment is especially valuable when a part requires both turning and secondary machining. Lange can review the part print, material, tolerances, quantity, and finishing requirements to determine whether the LB4000 EXII MY is the right fit for the project.
Better Accuracy Through Fewer Setups
Every time a part is moved from one machine to another, there is potential for added handling time, setup variation, and alignment challenges. The Okuma LB4000 EXII MY helps reduce those concerns by combining turning, live tooling, milling, drilling, and Y-axis machining capability in one platform.
When a project can be completed with fewer setups, customers may benefit from tighter relationships between features, improved concentricity, better repeatability, and more efficient throughput. This is important for parts where turned diameters, drilled features, milled surfaces, and contouring must work together accurately.
For complex industrial components, this added capability gives Lange more control over the finished result while helping customers reduce unnecessary outside handoffs.
Supporting Lange’s CNC Turning and Lathe Services
The Okuma LB4000 EXII MY directly supports Lange’s CNC turning and lathe services by adding advanced turning, live tooling, and Y-axis machining capability. This strengthens Lange’s ability to support customers that need precision turned parts, complex machined features, and multi-operation components.
It also supports Lange’s broader CNC machining services by giving customers another option for parts that require turning, milling, drilling, contouring, and secondary machining. For customers with repeat work, overflow machining, repair parts, or complex industrial components, this machine adds flexibility and capacity to Lange’s machining department.

Machining and Grinding Under One Roof
Many industrial parts require more than one process. A component may need turning before grinding, milling after turning, drilling before inspection, or finishing after material removal. Lange’s combination of machining and grinding equipment helps customers keep those related operations coordinated with one experienced provider.
The Okuma LB4000 EXII MY works together with Lange’s broader equipment lineup, including CNC vertical machining centers, CNC horizontal boring mills, planer mills, surface grinders, Blanchard grinders, inspection equipment, straightening equipment, and large-part handling capacity.
This under-one-roof approach can help reduce delays, improve communication, limit unnecessary transportation between vendors, and keep better control over quality from one operation to the next.

Useful for Repair, Production, and Contract Machining
The Okuma LB4000 EXII MY supports new part production, repair-related machining, and contract CNC machining work. Industrial customers often need a machining partner that can handle one-off parts, repeat parts, repair components, overflow work, and complex projects that involve multiple machining steps.
With live tooling and Y-axis capability, Lange can support parts that require more advanced turning and machining in a single setup. This makes the machine valuable for manufacturers, fabricators, repair facilities, OEMs, and industrial customers that need dependable CNC turning support backed by additional machining, grinding, and inspection capabilities.
Whether the project involves a new component, a replacement part, a repair part, or a multi-operation industrial component, Lange can review the requirements and recommend the right machining process for the job.
