| SERCO RTJ machine is designed for | - horizontal machining - facing | 
| - vertical machining - boring | |
| - conifal machining - RTJ (23°) or any angle (30°, 45°, etc.) | |
| RTJ technical principles: | |
| angular gearbox | driven by the rapid return system on the boring head | 
| universal joint | for transmitting the rotation movement in a vertical plane | 
| gear / wheel assembly | drives the gear vai the universal joint. the machine is positioned on the machine vernier scale support | 
| clutch system | for engaging the gear on the wheel for generating the down-feed movement at the angle defined beforehead | 
| down-feed | as per pre-defined angle |
