Deburr
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]
Southampton (/saʊθˈ(h)æmptən/ ⓘ) is a port city in Hampshire, England. It is located approximately 80 miles (130 km) south-west of London, 20 miles (32 km) west of Portsmouth, and 20 miles (32 km) south-east of Salisbury.[6][7] Southampton had a population of 253,651 at the 2011 census, making it one of the most populous cities in southern England.[2] Southampton forms part of the larger South Hampshire conurbation which includes the city of Portsmouth and the boroughs of Havant, Eastleigh, Fareham, and Gosport. A major port,[8] and close to the New Forest, Southampton lies at the northernmost point of Southampton Water, at the confluence of the River Test and Itchen,[9] with the River Hamble joining to the south. Southampton is classified as a Medium-Port City.[10]
Southampton was the departure point for the RMS Titanic[11] and home to 500 of the people who perished on board.[12] The Spitfire was built in the city[13] and Southampton has a strong association with the Mayflower, being the departure point before the vessel was forced to return to Plymouth. In the past century, the city was one of Europe's main ports for ocean liners. More recently, Southampton is known as the home port of some of the largest cruise ships in the world.[14] The Cunard Line maintains a regular transatlantic service to New York from the city. Southampton is also one of the largest retail destinations in the South of England.[15]
Southampton was heavily bombed during the Second World War during what was known as the Southampton Blitz. It was one of the major embarkation points for D-Day. In the Middle Ages Southampton was where troops left England for the Battle of Agincourt. It was itself raided by French pirates, leading to the construction of the fortified town walls, many of which still stand today. Jane Austen also lived in Southampton for a number of years. In 1964, the town of Southampton acquired city status, becoming the City of Southampton.[16]
Some notable employers in the city include the University of Southampton, Ordnance Survey, BBC South, Associated British Ports, and Carnival UK.[17]
