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]
North Lincolnshire is a unitary authority area with borough status in Lincolnshire, England. At the 2011 Census, it had a population of 167,446.[2] The administrative centre and largest settlement is Scunthorpe, and the borough also includes the towns of Brigg, Broughton, Haxey, Crowle, Epworth, Bottesford, Winterton, Kirton in Lindsey and Barton-upon-Humber. North Lincolnshire is part of the Yorkshire and the Humber region. The borough is mostly rural in character aside from near the town of Scunthorpe and near the Port of Immingham where most of the nearby villages and towns form part of the wider urban areas.
North Lincolnshire was formed following the abolition of Humberside County Council in 1996, when four unitary authorities replaced it, North Lincolnshire and North East Lincolnshire, on the south bank of the Humber Estuary, and the East Riding of Yorkshire and Kingston upon Hull on the north bank.

It is home to the Haxey Hood, a traditional event which takes place in Haxey on 6 January, a large football scrum where a leather tube (the "hood") is pushed to one of four pubs, where it remains until next year's game.
