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]
Clifton is a suburb and historic manor in the city of Nottingham, in Nottinghamshire, England. As of the 2021 census, it had a population of 22,936.[1]
Clifton has two council wards in the City of Nottingham (Clifton West and Clifton East as of 2018)[2] with a total population taken at the 2011 census (prior wards of Clifton North and Clifton South) of 26,835.[3][4] The location also encompasses Clifton Grove and Clifton Village, a residential area set alongside the River Trent.
The Manor of Clifton was for many centuries the seat of the de Clifton (later Clifton) family, branches of which were in the 17th century created Baron Clifton of Leighton Bromswold (1608) and Clifton baronets (1611). It is now the site of a council estate. The village is also notable for many old buildings including Clifton Hall, which is the former seat of the Clifton family, and St. Mary's Church.
Clifton is also home to the Nottingham Trent University Clifton Campus.
