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]
Chatteris /ˈtʃætɛrɪs/ is a market town and civil parish in the Fenland district of Cambridgeshire, England, situated in The Fens between Huntingdon, March and Ely. The town is in the North East Cambridgeshire parliamentary constituency.
The parish of Chatteris is large, covering 6,099 hectares, and for much of its history was a raised island in the low-lying wetland of the Fens. Mentioned in the Domesday Book of 1086, the town has evidence of settlement from the Neolithic period.[1] After several fires in the 18th and 19th centuries, the majority of the town's housing dates from the late Victorian period onwards, with the tower of the parish church the only medieval building remaining.
Following the draining of the Fens, beginning in the 17th century and completed in the 19th century, the town's economy has been based on agriculture and related industry. Due to its proximity to Cambridge, Huntingdon and Peterborough, the town has emerged as a commuter town. The town had a population of 11,011 at the time of the United Kingdom Census 2021.
