WHY CHOOSE OKUMA IMPACT LU-45

The Okuma Impact LU-45 remains one of the most respected large-frame CNC turning centers because it combines exceptional durability, powerful machining capability, and proven reliability. Manufacturers that routinely machine large workpieces often choose the LU-45 because it provides the stability and torque required for demanding cutting operations.

One of the machine’s greatest strengths is its rigid cast iron construction. The slant-bed design helps reduce vibration while improving chip evacuation and thermal stability. These characteristics contribute to longer tool life, improved surface finishes, and consistent dimensional accuracy.

The spindle system is designed for heavy material removal. Whether roughing large steel forgings or finishing precision-machined components, the machine delivers the power necessary to maintain productivity throughout the machining process.

The OSP7000L control system is another major advantage. Known for reliability and ease of use, the control provides conversational programming, diagnostics, and dependable operation.

HOW MUCH DOES A USED OKUMA IMPACT LU-45 COST?

A used 1998 Okuma Impact LU-45 typically sells for between $25,000 and $80,000, depending on machine condition, spindle hours, maintenance history, installed options, tooling packages, and overall configuration.

Machines near the lower end of the range generally have higher operating hours or fewer accessories. Machines near the upper end often include hydraulic chucks, chip conveyors, tailstocks, steady rests, tooling packages, upgraded workholding systems, and documented maintenance histories.

Machine condition remains the most important factor affecting value. Buyers typically inspect spindle condition, turret accuracy, machine geometry, lubrication systems, hydraulic systems, and overall operational performance. Machines with documented service records and strong maintenance histories generally command premium pricing.

Tooling and accessories can significantly increase machine value. Boring bars, tool holders, hydraulic workholding systems, steady rests, spare tooling, and setup equipment often represent thousands of dollars in additional value and can substantially impact the final selling price.

Market demand also influences pricing. Manufacturing regions with strong oil and gas, aerospace, power generation, mining, and heavy equipment industries often maintain consistent demand for large-capacity turning centers such as the LU-45.

Compared to purchasing a new heavy-duty CNC lathe, a used 1998 Okuma Impact LU-45 offers substantial cost savings while still providing outstanding machining capability, proven reliability, and long-term productivity. For manufacturers seeking a large-frame turning center capable of handling demanding applications, the LU-45 remains one of the best investments available in today’s used CNC equipment market.
