10.1 Overview
The sections below describe the tightening processes that are presently the most essential ones in tight-
ening technology. The tightening program steps described in chapter Operating system NEXO-OS (see
page 173) are used to program all standard tightening processes as well as special tightening processes.
Standard tightening processes include:
• Torque-controlled tightening process (see page 249)
• Angle-of-turn-controlled tightening process (see page 250)
In addition to standard tightening processes, it is also possible to program special tightening processes.
They are characterized by:
• A combination of various standard processes
• Execution of defined tightening cycles (multi-step tightening processes) to adjust the tightening pro-
cess to the tightening operation (e.g. speed adjustment)
Special tightening processes include:
• Loosening/retightening processes
• Self-tapping tightening processes
• Tightening of stop nuts/squeeze lock nuts
