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]
Falmouth (/ˈfælməθ/ FAL-məth; Standard Written Form: Aberfala[2]) is a town, civil parish and port on the River Fal on the south coast of Cornwall, England, United Kingdom.[3] It has a total resident population of 21,797 (2011 census).
In 1540, Henry VIII built Pendennis Castle in Falmouth to defend Carrick Roads. The main town of the district was then at Penryn. Sir John Killigrew created the town of Falmouth shortly after 1613.[7]
In the late 16th century, under threat from the Spanish Armada, the defences at Pendennis were strengthened by the building of angled ramparts. During the Civil War, Pendennis Castle was the second to last fort to surrender to the Parliamentary Army.[8]
After the Civil War, Sir Peter Killigrew received royal patronage when he gave land for the building of the Church of King Charles the Martyr, dedicated to Charles I, "the Martyr".[9]
