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]
Sandwell is a metropolitan borough of the West Midlands county in England. The borough is named after the Sandwell Priory, and spans a densely populated part of the West Midlands conurbation. According to Sandwell Metropolitan Borough Council, the borough comprises the six amalgamated towns of Oldbury, Rowley Regis, Smethwick, Tipton, Wednesbury, and West Bromwich,[3] although these places consist of numerous smaller settlements and localities. Sandwell's Strategic Town Centre is designated as West Bromwich, the largest town in the borough, while Sandwell Council House (the headquarters of the local authority) is situated in Oldbury.
Bordering Sandwell is the City of Birmingham to the east, the Metropolitan Borough of Dudley to the south and west, the Metropolitan Borough of Walsall to the north, and the City of Wolverhampton to the north-west. Spanning the borough are the parliamentary constituencies of West Bromwich West, West Bromwich East, Warley, and part of Halesowen and Rowley Regis, which crosses into the Dudley borough.
At the 2011 census, the borough had a population of 309,000 and an area of 86 square kilometres (33 sq mi).[4]
