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]
Poole (/puːl/ (audio speaker iconlisten)) is a large coastal town and seaport in Dorset, on the south coast of England. The town is 21 miles (34 km) east of Dorchester and adjoins Bournemouth to the east. Since 1 April 2019, the local authority is Bournemouth, Christchurch and Poole Council which is a unitary authority. Poole had an estimated population of 151,500 (mid-2016 census estimates) making it the second-largest town in the ceremonial county of Dorset. Together with Bournemouth and Christchurch, the conurbation has a total population of nearly 400,000.
Human settlement in the area dates back to before the Iron Age. The earliest recorded use of the town's name was in the 12th century when the town began to emerge as an important port, prospering with the introduction of the wool trade. Later, the town had important trade links with North America and, at its peak during the 18th century, it was one of the busiest ports in Britain. In the Second World War, Poole was one of the main departing points for the Normandy landings.
Poole is a tourist resort, attracting visitors with its large natural harbour, history, the Lighthouse arts centre and Blue Flag beaches. The town has a commercial port with cross-Channel freight and passenger ferry services, which connect with the Channel Islands of Jersey and Guernsey, as well as the French port town of Saint-Malo, Brittany.
The headquarters of the Royal National Lifeboat Institution (RNLI) is in Poole, and the Royal Marines have a base in the town's harbour. Despite their names, Poole is the home of The Arts University Bournemouth, the Bournemouth Symphony Orchestra and a significant part of Bournemouth University.
