Deburring
There are many deburring processes, but the most common are mass-finishing, spindle finishing, media blasting, sanding, grinding, wire brushing, abrasive flow machining, electrochemical deburring, electropolishing, thermal energy method, machining, water jet deburring, and manual deburring.[5]
Manual
Manual deburring is the most common deburring process because it is the most flexible process. It also only requires low cost tools and allows for instant inspection.[6] Manual deburring is either done with tools like scrapers, files, sandpaper, stones and reamers or with handheld power tools that use abrasive points, sandpaper, or cutters similar to those used to deburr during machining.
Electrochemical
Electrochemical deburring is the use of electrochemical machining to deburr precision work pieces and edges that are hard-to-reach, such as intersecting holes. The process uses a salt or glycol solution and electricity to dissolve the burr. The electric current is applied with a specialized tool to reach the burr location. Burrs are removed in 5 to 10 seconds, while the rest of the work piece is unaffected.[6]
Thermal
Thermal energy method (TEM), also known as thermal deburring, is a deburring process used to remove hard-to-reach burrs or burrs from multiple surfaces at the same time. The process uses an explosive gas mixture to provide thermal energy to burn off the burrs. It is the fastest burr removal process, requiring only 20 milliseconds to remove a burr.[7]
The process starts by loading the workpiece into an explosion-proof chamber, which is then sealed and clamped with approximately 220 metric tons (240 short tons). The chamber is then evacuated of air and filled with an oxygen and fuel mix; this mixture is pressurized to 0.5 to 1.9 MPa (73 to 276 psi). An electrical igniter then ignites the mixture, which burns for approximately 20 milliseconds, causing all of the sharp corners and burrs to burn away. The peak temperature reaches 3,000 °C (5,430 °F).[7]
Gedling is a village and former civil parish which gives its name to the larger Borough of Gedling in Nottinghamshire, England. It lies 4 miles (6.4 km) north-east of Nottingham city centre. The parish was abolished in 1935 and absorbed into the urban district of Carlton, which in turn was abolished in 1974 on the creation of borough of Gedling. The population of the Gedling ward at the 2011 census was 6,817[1] and 111,787 for the district.[2] Gedling was recorded in the Domesday Book and is still a distinct settlement, although residential, commercial and industrial growth in the wider borough of Gedling and the neighbouring city of Nottingham, boroughs of Broxtowe and Rushcliffe and district of Ashfield (as well as the Derbyshire boroughs of Amber Valley and Erewash, which have become increasingly urban around Nottingham) means it can be difficult to distinguish the village of Gedling from the nearby town of Carlton, with which it has become contiguous.
Gedling was first settled around Saxon times, when the Saxon chief Gedl (hence the name Gedling, coming from the chief "Gedl" and "Ing" being Saxon for People, Gedl-Ing meaning "Gedl's People") sailed up the River Trent, and then up the Little Ouse dyke, until he could get no further upstream. He landed at the spot which is thought to be the present-day site of All Saints' Church. Gedling has had several versions of its name including Ghellinge, Gedlinga, Geddlings, and Gettang.
Despite being a fairly small place, Gedling gives its name to the local borough council which has its offices in nearby Arnold, and also to the local parliamentary constituency, which covers the suburbs to the east of Nottingham, including Arnold and Carlton. Village pubs are the Gedling Inn (once the Chesterfield Arms) and The Willowbrook on Main Road.
