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]
Fakenham is a market town and civil parish in Norfolk, England. It is situated on the River Wensum, about 25 miles (40 kilometres) north west of Norwich. The town is the junction of several local roads, including the A148 from King's Lynn to Cromer, the A1067 to Norwich and the A1065 to Swaffham.
The civil parish has an area of 3.49 sq mi (9.0 km2) and in the 2001 census had a population of 7,357 in 3,292 households, the population increasing to 7,617 at the 2011 census.[1] For the purposes of local government, the parish falls within the district of North Norfolk.[2]
Fakenham has been a market town since 1250, particularly known for its corn, barley and wheat trading, and in the 19th century it became noted for its printing. Fakenham Racecourse is a thoroughbred horse racing venue to the south of Fakenham, of which Charles, Prince of Wales is patron.
The town has a long name of Fakenham Lancaster which derives from the ownership of the manor in 1377 being transferred to John of Gaunt, the Duke of Lancaster. The name continues to be used today, including on recently placed history trail plaques around the town,[3] and also the two wards that cover the town, for the purpose of electing councillors to North Norfolk District Council, are called Lancaster North and Lancaster South.
