USED OKUMA L-300-MYW-E – 2018

The OKUMA L-300-MYW-E – 2018 is a 5-axis CNC turning center from the GENOS L-series, configured for turning, live-tool milling, Y-axis machining, and secondary operations using a sub-spindle. This configuration combines a 10″ main-spindle chuck, 6″ sub-spindle chuck, 12-station live-tool turret, Y-axis capability, and Okuma’s OSP-P300LA-e One-Touch IGF CNC control.

The machine provides approximately 20.47″ of swing, 11.81″ maximum turning diameter, and 17.72″ machining length. Its 2.54″ bar capacity makes it suitable for production work involving medium-sized bar stock, while the sub-spindle allows parts to be transferred for back-side machining without a separate setup.

The main spindle is rated at 3,000 RPM with a 20 HP motor, while the sub-spindle reaches 6,000 RPM with a 10 HP motor. The 12-station turret provides live-tool capability at up to 4,500 RPM, with Y-axis travel of approximately 3.94″ (±1.97″).

With its combination of turning, milling, Y-axis, C-axis, and sub-spindle machining, the OKUMA L-300-MYW-E is well suited for manufacturers producing complex shafts, fittings, housings, connectors, automotive components, hydraulic parts, and other precision components requiring multiple operations in one setup. Current used listings also show equipment such as bar feeders, parts catchers, tool presetters, chip conveyors, and high-pressure coolant systems on individual machines.

INDUSTRIES THAT USE OKUMA L-300-MYW-E

The OKUMA L-300-MYW-E is designed for production environments where turning and secondary milling operations need to be completed efficiently on the same machine. Its Y-axis live tooling and sub-spindle make it particularly useful for components requiring machining on multiple faces.

Common industries include:

• Automotive
• Aerospace
• Medical
• Oil and gas
• Hydraulic and pneumatic equipment
• Industrial machinery
• Energy
• General precision manufacturing
• Contract machining
• Defense

The machine’s 2.54″ bar capacity and 11.81″ maximum turning diameter make it appropriate for a broad range of medium-sized production components.

---

TYPICAL PARTS THE OKUMA L-300-MYW-E CAN PRODUCE

The machine is well suited for components that require turning combined with milling, drilling, tapping or back-side machining.

Typical parts include:

• Shafts
• Hydraulic components
• Valve components
• Bushings
• Flanges
• Fittings
• Automotive components
• Pump components
• Couplings
• Precision housings
• Threaded components
• Complex turned-and-milled parts

The combination of the live-tool turret, Y-axis, C-axis and sub-spindle allows many secondary machining operations to be completed without transferring the workpiece to another machine.

WHY CHOOSE OKUMA L-300-MYW-E?

The biggest advantage of the OKUMA L-300-MYW-E is its multitasking capability. A conventional 2-axis turning center may require a separate machining center for cross-drilling, milling or off-center features. The L-300-MYW-E adds Y-axis and live-tool capability while also providing a sub-spindle for secondary operations.

The 10″ main chuck, 6″ sub-spindle chuck, 2.54″ bar capacity, 20 HP main spindle and 12-station live-tool turret make this machine particularly attractive for production machining. The OSP-P300LA-e control and One-Touch IGF system also provide conversational programming capabilities for shops working with a wide variety of components.

WHY BUY USED OKUMA L-300-MYW-E?

Buying a used OKUMA L-300-MYW-E – 2018 can provide access to a relatively modern multitasking CNC turning center without the acquisition cost of a new machine. The machine’s combination of Y-axis milling, live tooling, C-axis control and sub-spindle capability can replace several separate machining operations.

Many used machines include valuable options such as:

• Okuma OSP-P300LA-e CNC control
• 10″ Kitagawa main chuck
• 6″ Kitagawa sub-spindle chuck
• 12-station live-tool turret
• Y-axis
• Full C-axis on both spindles
• Tool presetter
• Parts catcher
• Chip conveyor
• Bar feeder
• High-pressure coolant
• Mist collector
• Axial live-tool holders
• Radial live-tool holders

Before purchasing a used L-300-MYW-E, buyers should inspect both spindle condition, C-axis operation, Y-axis accuracy, turret indexing, live-tool performance, chuck condition, hydraulic systems, coolant system, chip conveyor, CNC control, axis backlash and available service records. One 2018 example currently advertised has only 781 cutting hours, while other machines can have substantially higher operating hours, making machine-specific inspection particularly important.

HOW MUCH DOES A USED OKUMA L-300-MYW-E COST?

Used pricing for a 2018 OKUMA L-300-MYW-E depends heavily on spindle and cutting hours, machine condition, bar feeder configuration, tooling, chuck package, chip conveyor, coolant options and included accessories. Current listings frequently use Request a Quote rather than publishing a fixed asking price.

A current 2018 listing for the L-300-MYW-E is offered by ACT Machinery with a 10″ main chuck, 6″ sub-spindle chuck, Y-axis, 12-station live-tool turret, tool presetter, parts catcher and chip conveyor, but the asking price is listed as Request a Quote.

When evaluating the price of a used L-300-MYW-E, buyers should compare cutting hours, power-on hours, spindle condition, sub-spindle condition, live-tool condition, Y-axis accuracy, included tooling, bar feeder, chip conveyor, coolant system and service history rather than relying on the 2018 model year alone.
