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]
Reading (/ˈrɛdɪŋ/ (audio speaker iconlisten) RED-ing)[2] is a historic large market town in Berkshire, England, in the Thames Valley at the confluence of the rivers Thames and Kennet. It is on the Great Western Main Line railway and the M4 motorway, 40 miles (64 km) east of Swindon, 25 miles (40 km) south of Oxford, 40 miles (64 km) west of London, 15 miles (24 km) north of Basingstoke, 13 miles (21 km) southwest of Maidenhead and 15 miles (24 km) east of Newbury. Reading is a major commercial centre, especially for information technology and insurance.[3] It is also a regional retail centre, serving a large area of the Thames Valley, and home to the University of Reading. Every year it hosts the Reading Festival, one of England's biggest music festivals. Among its sports teams are Reading Football Club and Reading Hockey Club, and over 15,000 runners annually compete in the Reading Half Marathon.
Reading dates from the 8th century. It was an important trading and ecclesiastical centre in the Middle Ages, the site of Reading Abbey, one of the largest and richest monasteries of medieval England with strong royal connections, of which the 12th-century abbey gateway and significant ancient ruins remain. By 1525, Reading was the largest town in Berkshire, and tenth in England for taxable wealth. The town was seriously affected by the English Civil War, with a major siege and loss of trade, but played a pivotal role in the Glorious Revolution, whose only significant military action was fought on its streets. The 18th century saw the beginning of a major ironworks in the town and the growth of the brewing trade for which Reading was to become famous. The 19th century saw the coming of the Great Western Railway and the development of the town's brewing, baking and seed growing businesses, and the town grew rapidly as a manufacturing centre.
