Groove (technology)
The groove , also groove (plural: the grooves ), is a term used in technical terminology for an elongated recess.
Word origin
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:
-
cutting
- 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
-
transforming
- 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:
- Mortar
- 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
use
- in mechanical engineering
- as a "counterpart" to seals , clamping rings , Simmerrings and the like;
- as a guide bearing ;
- T-slots on machine tool clamping tables for fixing workpieces ;
- in electrical machines as a device in which current-carrying coils are located;
- glued or detachable as a wood connection
- for longitudinal connection by means of bunging ;
- for longitudinal connection by means of tongue and groove connection ;
- for vertical connection by means of a ridge ;
- to accommodate an insert as a frame ;
- for setting the soil in vessels, etc. in the cooperage ;
- in print finishing
- In post- print processing, grooving or grooving means cutting out a material chip from thick cardboard or cardboard in order to enable or simplify bending of the material.
