Nut is a Middle High German word that comes from wood processing . It only found its way into metal processing later.
How it works and manufacture
Grooves are used to fix elongated components (as form-fitting connections ), to guide or to countersink them. In other cases, the removal of material creates space.
The groove can have a rectangular cross-section or a trapezoidal shape, with an outwardly sloping wall or as a dovetail .
Grooves are produced:
- with the milling machine in numerous materials
- with form cutter in the turning shop
- grinding in one step or after creating parting lines with a chisel in stone and related reactive materials
- pushing or planing with special tools in wood, but also metals or plastics
- with saws in wood-based materials and along and across the grain in solid wood
- with metals also pulling with a keyseating machine
- Broach with a broach
- with roller presses
In the manual processing of solid wood, the difference between the longitudinal groove along the wood fiber and the transverse groove is decisive: the former can be planed, the latter can only be sawn . When using a router or a table router , the distinction is irrelevant. Special hand tools used in woodworking are:
- Burr saw and planer or chisel
- Slot iron , a special chisel that cuts the base and wall ([profile)
- Dexel - here, too, there are special Nutendexels
- in mechanical engineering
- glued or detachable as a wood connection
- in print finishing
