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]
Luton (/ˈluːtən/ ⓘ)[7] is a town and unitary authority with borough status in Bedfordshire, England, with a population at the 2021 census of 225,262.[5][8]
Luton is on the River Lea, 32 miles (50 km) north-west of London,[9] 18 miles (29 km) north-west of Hertford, 20 miles (32 km) south of Bedford[9] and 23 miles (37 km) south-east of Milton Keynes. The town's foundation dates to the sixth century as a Saxon settlement on the river, from which Luton derives its name.[10] Luton is recorded in the Domesday Book as Loitone and Lintone.[11] One of the largest churches in Bedfordshire, St Mary's Church, was built in the 12th century.[12] There are local museums which explore Luton's history in Wardown Park[13] and Stockwood Park.[14]
Luton was once known for hatmaking and also had a large Vauxhall Motors factory. Car production at the plant began in 1905 and continued until its closure in 2002.[15] Production of commercial vehicles continues and the head office of Vauxhall Motors is in the village of Chalton on the northern border of the borough .[16] London Luton Airport opened in 1938 and is now one of Britain's major airports,[17] with three railway stations also in the town. The University of Bedfordshire was created from a merger with the University of Luton;[18] two of its campuses are in Luton.[19]
Luton Town Football Club, nicknamed the Hatters, due to the town's connection to hatmaking, has had several spells in the top flight of the English league as well as a Football League Cup triumph in 1988. They play at Kenilworth Road, their home since 1905; planning permission for a new larger stadium was approved in 2019.[20] Luton International Carnival, the largest one-day carnival in Europe, is held on the day before the last Monday in May;[21][n 1] the Saint Patrick's festival is held on the weekend nearest to Saint Patrick's Day[22] as there is a large Irish community in Luton. The town also has a large Pakistani community which, along with the Irish, were attracted to employment at the Vauxhall car plant.[23][24] Luton Hoo is an English country house, estate and Grade I listed building originally designed by Scottish architect Robert Adam but later transformed to the designs of Robert Smirke.[25]
