USED OKUMA LOC650

The OKUMA LOC650 is a heavy-duty horizontal CNC lathe specifically designed for oil country applications, with a strong focus on precision pipe threading and large-diameter turning. As part of Okuma’s LOC (Lathe Oil Country) series, it is engineered to meet the demanding requirements of industries such as oil & gas, pipeline manufacturing, and heavy engineering, where accuracy, repeatability, and durability are critical.

A defining feature of the LOC650 is its 4-axis configuration, which allows it to perform highly precise threading operations on large pipes. The machine is equipped with Okuma’s Oil Field “Threading Suite,” a proprietary system that integrates variable speed threading with harmonic spindle control. This ensures an exact match between cutting increments and infeed patterns, resulting in superior thread quality and consistency.

The LOC650 offers a maximum turning diameter of approximately 650 mm and a turning length of around 1,750 mm, making it suitable for long tubular components. It also features three spindle bore variations, enabling it to accommodate a wide range of pipe sizes without requiring multiple machines.

In terms of performance, the machine delivers strong spindle power in the range of 45/37 kW (with higher optional configurations), along with a speed range of up to 500 rpm. Its robust construction, including heavy-duty castings and rigid guideways, ensures stability during high-load operations and long production cycles.

The LOC650 typically includes a turret system with multiple tool positions and optional live tooling, allowing for additional machining flexibility beyond threading. Automation compatibility, such as loaders and pallet systems, further enhances productivity.

Overall, the LOC650 is a specialized, high-performance machine built for precision, efficiency, and long-term reliability in demanding oilfield and heavy machining environments.

WHY BUY USED OKUMA LOC650

Purchasing a used OKUMA LOC650 is a practical and cost-effective solution for companies involved in oilfield machining and large pipe production. Given its specialized design and heavy-duty construction, the LOC650 retains strong value and performance even after years of operation, making it a reliable option in the secondary market.

One of the main advantages of buying used is significant cost savings. New oil country lathes like the LOC650 require a large capital investment due to their size, power, and specialized threading capabilities. A used machine allows manufacturers to access these capabilities at a fraction of the cost while maintaining similar operational efficiency.

Another important factor is its application-specific performance. The LOC650 is purpose-built for threading large pipes, and its Threading Suite ensures precise synchronization between spindle speed and feed rates. This results in high-quality threads, reduced rework, and improved production consistency—critical factors in industries where tolerances are strict.

Cutting time is a key consideration when evaluating used machines. Since LOC650 units are often used in high-production environments, total cutting hours can vary significantly. Machines with lower cutting hours typically have less wear on spindle bearings, guideways, and turret systems, leading to better accuracy and reliability. However, even high-hour machines can remain productive due to Okuma’s robust engineering and durable components.

Durability is another major advantage. The LOC650 is built with heavy-duty materials and designed for continuous operation, allowing it to remain in service for decades with proper maintenance. This longevity makes it a dependable investment in the used market.

Additionally, Okuma’s global support network and availability of spare parts ensure that even older machines can be maintained effectively. Buyers can continue to operate and service the machine without major concerns about obsolescence.

In summary, a used LOC650 offers strong cost savings, proven performance, and long-term reliability, making it an excellent choice for specialized pipe threading and heavy turning applications.

HOW MUCH DOES A USED OKUMA LOC650 COST?

The cost of a used OKUMA LOC650 varies based on machine age, condition, configuration, and total cutting time. As a specialized oil country lathe, its value in the secondary market is closely tied to how extensively it has been used and how well it has been maintained.

For machines manufactured before 2000, pricing typically ranges from $50,000 to $150,000. These units usually have very high cutting hours (40,000–70,000+ hours) and may require refurbishment, including spindle repairs, turret servicing, or control upgrades. While they represent the lowest entry cost, buyers should factor in potential maintenance expenses.

Machines built between 2000 and 2010 are more commonly available and generally fall within the range of $150,000 to $300,000. These machines often offer a good balance between cost and performance, especially if they have moderate cutting hours (20,000–40,000 hours) and documented maintenance history. They remain widely used in oilfield applications due to their reliability and threading accuracy.

For machines manufactured between 2010 and 2025, prices typically range from $300,000 to $550,000 or more depending on configuration and condition. Newer machines benefit from updated CNC controls, improved automation compatibility, and lower cutting hours. Units with less than 15,000–20,000 hours are considered premium and command higher prices due to their longer remaining service life.

Cutting time is one of the most critical pricing factors. Lower-hour machines generally have less wear on key components such as spindle bearings and guideways, resulting in better performance and lower maintenance costs. High-hour machines may be cheaper upfront but can require additional investment over time.

In conclusion, understanding the relationship between machine age, cutting time, and condition is essential when evaluating a used LOC650. A well-maintained machine with moderate hours typically offers the best balance between cost and long-term productivity.
