USED OKUMA MULTUS B300-W – 2006

The OKUMA MULTUS B300-W – 2006 is a 5-axis CNC multitasking turn-mill center designed to combine turning, milling, drilling, tapping, boring, and other machining operations in a single machine platform. The MULTUS B300-W is equipped with a main spindle, opposing sub-spindle, Y-axis movement, B-axis rotary milling capability, and C-axis control, making it suitable for complex parts that would otherwise require multiple machines or setups.

This 2006 OKUMA MULTUS B300-W provides a substantial working envelope, with approximately 24.8 inches of swing over the bed, 17.72 inches of maximum turning diameter, 35.43 inches of distance between spindles, and 22.83 inches of X-axis travel. The W-axis sub-spindle travel provides additional flexibility for transferring and supporting workpieces during machining.

The machine is commonly configured with an OKUMA OSP-P200L CNC control, a 10-inch main chuck, an 8-inch sub-spindle chuck, automatic tool changing, live tooling, through-spindle coolant, parts catcher, tool presetter, and chip conveyor. Individual used machines can have different equipment packages, so the exact configuration should be confirmed before purchase.

The MULTUS B300-W is particularly useful for manufacturers producing complex turned-and-milled components. Its multitasking design allows turning and milling operations to be performed without removing the workpiece from the machine, which can reduce setup time and improve positional consistency between machining operations.

WHY CHOOSE OKUMA MULTUS B300-W

The OKUMA MULTUS B300-W combines CNC turning and milling capabilities with 5-axis functionality, a main spindle, opposing sub-spindle, Y-axis movement, B-axis positioning, and C-axis control.

Its approximately 17.72-inch maximum turning diameter, 35.43-inch distance between spindles, and 580 × 935 mm X/Z travel provide a substantial machining envelope for a multitasking CNC machine.

The combination of turning and milling can reduce the number of separate setups required for complex components. Instead of transferring a part between a CNC lathe and machining center, many operations can be completed on the MULTUS B300-W.

The machine is also capable of supporting automated tool management, live tooling, parts catching, through-spindle coolant, and chip-conveyor systems depending on configuration.

WHY BUY USED OKUMA MULTUS B300-W

Buying a used OKUMA MULTUS B300-W can give manufacturers access to a sophisticated multitasking CNC platform at a lower acquisition cost than purchasing a comparable new turn-mill center.

A properly maintained 2006 machine can provide capabilities including:

• 5-axis machining
• CNC turning
• CNC milling
• Y-axis machining
• B-axis angular machining
• C-axis interpolation
• Main and sub-spindle machining
• Live tooling
• Automatic tool changing
• Rigid tapping
• Helical cutting
• Parts catching
• Through-spindle coolant
• Chip conveyor
• Tool presetting
• Bar-feed interface

Before purchasing a used MULTUS B300-W, buyers should inspect the main spindle, sub-spindle, live-tool spindle, B-axis, C-axis, Y-axis, ball screws, linear guides, chuck condition, spindle bearings, tool changer, CNC control, turret, coolant system, chip conveyor, lubrication system, electrical system, and machine geometry.

Particular attention should be paid to the condition and accuracy of the B-axis and C-axis because these components are critical to the machine’s multitasking and 5-axis capabilities.

HOW MUCH DOES A USED OKUMA MULTUS B300-W COST?

The price of a used OKUMA MULTUS B300-W varies according to machine condition, spindle hours, cutting hours, included tooling, control condition, spindle condition, tool magazine capacity, bar feeder, chip conveyor, coolant system, probing, parts catcher, and other accessories.

For a 2006 OKUMA MULTUS B300-W, buyers should evaluate the actual machine rather than relying only on the year or model when comparing asking prices. Individual machines can have significantly different equipment packages.

The value of a used MULTUS B300-W can be affected by whether it includes equipment such as:

• OKUMA OSP-P200L control
• Main and sub-spindle
• Live tooling
• 5-axis capability
• Tool presetter
• Parts catcher
• Through-spindle coolant
• Chip conveyor
• Bar feeder
• Additional tool holders
• Probing
• Tool management system

Buyers should also account for transportation, rigging, installation, electrical connection, leveling, tooling, coolant, and machine inspection when calculating the total acquisition cost.

A used OKUMA MULTUS B300-W – 2006 can therefore be evaluated based on its complete configuration, maintenance history, operating hours, spindle condition, axis accuracy, and included accessories rather than the model year alone.
