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]
Swindon (/ˈswɪndən/ (listen)) is the largest town in Wiltshire, South West England, lying between Bristol, 35 miles (56 kilometres) to the west, and Reading, the same distance to the east. The town is 71 miles (114 km) west of London. The population of the Swindon built-up area was 185,600 in 2011.[1]
The Town Development Act 1952 led to a major increase in its population.[2]
Swindon railway station is on the line from London Paddington to Bristol. Swindon Borough Council is a unitary authority, independent of Wiltshire Council since 1997. Residents of Swindon are known as Swindonians. The town is home to the offices of English Heritage, the Historic England Archive (formerly the National Monuments Record Centre) and the headquarters of the National Trust (all three are on parts of the site of the former Great Western Railway's Swindon Works), and the head office of the Nationwide Building Society.
