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]
Matlock is the county town of Derbyshire, England. It is situated at the south-eastern part of the Peak District, with the National Park directly to the west. The town is twinned with the French town of Eaubonne. The former spa resort of Matlock Bath lies immediately south of the town on the A6. The civil parish of Matlock Town had a population in the 2011 UK census of 9,543.[1] The population of the wider Matlock urban area (including Darley Dale, Tansley, Hackney and Matlock Bath) is approximately 20,000.
Matlock is nine miles (14 km) south-west of Chesterfield and in easy reach of the cities of Derby (19 miles), Sheffield (20 miles) and Nottingham (29 miles); the Greater Manchester conurbation is 30 miles away. Matlock is within the Derbyshire Dales district, which also includes the towns of Bakewell and Ashbourne, as well as Wirksworth. The headquarters of Derbyshire County Council are in the town.
