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
are used to program all standard tightening processes as well as special tightening processes.
Standard processes include:
•
Torque-controlled tightening process
•
Angle-of-turn-controlled tightening process
Besides standard processes, special processes can also be programmed. 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
