VERSATILE SOLUTION FOR LARGE-PART MANUFACTURING

Okuma presents new 4-axis lathe LU7000 EX

Okuma’s new 2-saddle lathe LU7000 EX is equipped with a high-power spindle and allows for turning large workpieces. The machine offers maximum productivity and excellent dimensional accuracy. Providing a large variety of features and modifications, the 4-axis lathe can be customised in accordance with the client’s individual requirements, making it suitable for a multitude of applications.

Especially when turning large and heavy workpieces with diameters of up to 900 mm, Okuma’s new LU7000 EX reveals its true potential. Equipped with a bed that is two-metres long, even very long parts can be machined with the lathe. Also difficult-to-cut materials pose no problem to the machine tool. A self-travelling tailstock allows for easy setups of long workpieces. These specifications make the LU7000 EX the ideal choice for the manufacturing of oil and gas industry parts.

High cutting performance
The LU7000 EX was developed with a clear focus on productivity. Therefore, the machine is equipped with two turrets that can be utilised simultaneously. As a first-in-this-class, the lathe offers a milling turret which allows for a high chip removal rate of up to 120 cm³/min. For ideal cutting conditions, manufacturers can choose from different main spindles with sizes ranging from a bore diameter of 200 mm with a max spindle speed of 1,500 min-1 to a bore diameter of 560 mm with a max speed of 350 min-1.

Special attention to precision
When designing the LU7000 EX, Okuma also focused on achieving high dimensional accuracy. The lathe’s high constructional rigidity but also Okuma’s Thermo-Friendly Concept are contributing to that. The application avoids a generation of immoderate heat during the manufacturing process, detects changes in temperature and compensates for thermal deformation. This way, inaccuracies due to thermal changes can be prevented. In addition, the Intelligent Technology application Machining Navi T-g masters to improve the surface quality. During threading, the technology adjusts spindle and cutting speeds to reduce chatter and increase manufacturing quality of threads. Manufacturers can customise the LU7000 EX with enhancements such as a follower rest, to adjust to their demands.
