Internal turning of workpieces
Vibration-damped boring bars
The internal turning of workpieces is one of the most common turning processes in the machining industry. In contrast to external turning, the choice of tool for internal turning is determined by the machining diameter (drilling diameter) and the length of the component.
An unfavorable length-to-diameter ratio of the boring bar can quickly lead to vibration problems. With the new T-Absorber series, Ingersoll Werkzeuge is introducing a completely new series of vibration-damped boring bars for large L/D ratios.
To cover the entire spectrum of internal machining, Ingersoll offers a comprehensive selection of high-quality internal boring bars. Different boring bars are used depending on the specified L/D ratio of the bore to be machined. With a maximum length-to-diameter ratio of the boring bars of 4xD, boring bars made of solid steel are generally used. Drill rods with a length-to-diameter ratio of more than 4xD up to around 6xD are manufactured with a solid carbide shank. An even more unfavourable length-to-diameter ratio of the required boring bar can only be achieved with a vibration-damped boring shank.
Ingersoll T-Absorber vibration-damped boring bars are special boring bar systems with "active" vibration damping. The T-Absorber series boring bars are designed to significantly reduce or even completely eliminate vibration when machining with large overhangs from 7xD to 14xD. Inside these tools is a unique damping mechanism consisting of a heavy metal weight supported by an oil-filled rubber spring element to further increase the required damping effect. The system also contains other elements to reduce vibrations.
The vibration-damped tools in the T-Absorber series can be equipped with a variety of internal turning heads. These heads can then be fitted with a large selection of indexable inserts, so that the right combination can be produced for almost any application.
The correct geometry of the indexable insert is just as important for vibration damping as the right choice of boring bar.
