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]
Rugby is a market town in Warwickshire, England, close to the River Avon. The town has a population of 70,628 (2011 census[1]) making it the second-largest town in the county. The town is the main settlement within the larger Borough of Rugby which has a population of 100,500 (2011 census).
Rugby is on the eastern edge of Warwickshire, near the borders of Leicestershire and Northamptonshire. It is 83 miles (134 km) north of London, 30 miles (48 km) east-southeast of Birmingham, 11 miles (18 km) east of Coventry, and 19 miles (31 km) south southwest of Leicester.
Rugby was a small rural market town until the mid-19th century, when the siting of a major railway junction at the town spurred the development of manufacturing and engineering industry, and the rapid growth of population.
Rugby School, an independent school situated in the town, is the birthplace of Rugby football, which according to legend, was invented in 1823, by a Rugby schoolboy William Webb Ellis.[2] The school was founded in 1567, and rose to national prominence as a public school in the 18th century.
