Used Okuma Machines

Okuma Vertical Machining Centers

Okuma vertical machining centers are widely used for milling operations involving aluminum, steel, stainless steel, and other materials.

One of the most widely recognized machine families is the MB Series, which has been produced since the early 2000s.

Common machines include:

• MB-4000H (early 2000s – 2010s)
• MB-5000H (2000s – 2010s)
   

These machines are known for their rigid construction and reliable performance in production machining environments.

More recent vertical machining center platforms include the GENOS M Series, which was introduced during the 2010s as a compact, high-performance vertical machining center designed for job shops and production machining.

Common models include:

• GENOS M560-V (2010s – present)
• GENOS M460-V (2010s – present)
   

In the Okuma naming convention, the model number often reflects the machine’s table size or machining envelope.

Okuma Horizontal Machining Centers

Horizontal machining centers are commonly used for production machining where pallet changers allow shops to machine multiple parts without stopping the spindle.

Okuma horizontal machining centers are well known through the MA Series and MB-H Series.

Popular machines include:

• MA-400HA (1990s – early 2000s)
• MA-600HB (2000s)
• MB-4000H (2000s – 2010s)
   

These machines are commonly used in industries such as automotive manufacturing, heavy equipment production, and aerospace machining.

The model number typically corresponds to the pallet size or machining capacity, helping buyers quickly determine the appropriate machine for their production requirements.

Okuma CNC Lathes

Okuma CNC lathes are widely used for high-precision turning operations. These machines are commonly used to produce shafts, housings, and cylindrical components used in industrial equipment and mechanical assemblies.

One of the most widely known Okuma turning center families is the LB Series.

Popular machines include:

• LB3000 EX (2000s – present)
• LB4000 EX (2000s – present)
   

In the LB naming structure, the number typically refers to the machine size and turning capacity.

Another widely used lathe platform is the GENOS L Series, which provides compact turning centers designed for efficient production machining.

Common models include:

• GENOS L3000 (2010s – present)
   

These machines are often equipped with live tooling and Y-axis capabilities, allowing milling operations to be performed directly on the lathe.

Okuma B-Axis CNC Lathes

Okuma B-axis CNC lathes allow milling and turning operations to be performed within the same machine platform.

These machines are typically part of Okuma’s MULTUS Series, which combines multi-axis milling and turning capabilities.

Common machines include:

• MULTUS B200 (2000s – present)
• MULTUS B300 (2010s – present)
   

In the MULTUS naming convention, the “B” indicates the presence of a B-axis milling spindle, allowing the machine to approach the part from multiple angles.

These machines are widely used in aerospace and medical manufacturing where complex geometries must be produced with high precision.

Okuma Multi-Spindle CNC Lathes

Multi-spindle CNC lathes are designed for high-volume production environments where multiple parts can be machined simultaneously.

Okuma has developed several multi-spindle turning platforms designed to increase productivity in industries such as automotive manufacturing and precision component production.

These machines allow manufacturers to significantly reduce cycle times when producing large quantities of parts.

Okuma Vertical Turret Lathes

Vertical turret lathes (VTLs) are used to machine large, heavy components such as gears, bearings, and industrial housings.

Okuma produces vertical turning centers such as those in the VTM Series, which combine vertical turning with milling capability.

Common machines include:

• VTM-1200 (2000s – present)
• VTM-2000 (2010s – present)
   

These machines are frequently used in industries such as energy production, heavy equipment manufacturing, and aerospace machining.

Okuma Mill-Turn Machines

Mill-turn machines combine turning and milling operations within a single machine platform.

Okuma’s most well-known mill-turn machines are part of the MULTUS Series, which allows manufacturers to perform complex multi-axis machining operations in a single setup.

Machines such as the MULTUS U3000 and MULTUS U4000 are widely used in industries requiring high-precision complex components.

These machines are commonly used in aerospace, medical manufacturing, and high-precision mechanical component production.

Okuma Grinding Machines

In addition to machining centers and turning centers, Okuma also manufactures precision grinding machines used in finishing operations.

Cylindrical Grinders

Cylindrical grinding machines are used to grind external diameters of cylindrical parts with extremely tight tolerances.

Okuma cylindrical grinders are commonly used in industries requiring high-precision shafts and rotating components.

ID Grinders

Internal diameter (ID) grinders are used to grind the internal surfaces of components such as bearing races and precision mechanical housings.

These machines allow manufacturers to achieve extremely tight tolerances on internal features.

OD Grinders

Outside diameter (OD) grinders are used for finishing external surfaces of precision components. These machines are frequently used in industries such as aerospace, automotive manufacturing, and toolmaking.

Why Buyers Look for Used Okuma Machines

Buyers searching for used Okuma machines are often looking for equipment that offers:

• strong machine construction and durability
• highly accurate machining performance
• proprietary Okuma OSP CNC controls
• advanced multi-axis machining capability
• strong reputation for reliability in production environments
   

Another reason Okuma machines perform well in search traffic is that buyers frequently search by specific model families, such as LB3000 EX lathes, MULTUS mill-turn machines, or GENOS machining centers.

Including these machine families helps buyers quickly determine whether a machine matches their production requirements.
