16.14 2 ● It is recommended to use a C-type clamping sleeve for increased tool clamping rigidity, with a clamping length more than 4*DCONMS. ● When using longer and heavier damping boring bars on horizontal lathes, it is advised to use a center support to reduce vibration and improve machining precision and stability. ● The boring bars are equipped with internal cooling channels. It is recommended to use external or internal cooling methods to cool the damping area, which helps prevent the aging of internal sealing components and extends tool life. ● When using a boring bar for the first time, use a calibration tool to adjust the boring bar to a horizontal position (parallel to the X-axis of the machine tool) to ensure the correct center height; otherwise, the insert may break unexpectedly. ● For better performance in parts processing, please consult the regional sales consultant before purchasing to evaluate the working conditions and provide a suitable matching solution.
