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]
Salisbury (locally /ˈsɔːzb(ə)ri/ SAWZ-b(ə-)ree)[a] is a cathedral city in Wiltshire, England with a population of 41,820,[1] at the confluence of the rivers Avon, Nadder and Bourne. The city is approximately 20 miles (30 kilometres) from Southampton and 30 miles (50 kilometres) from Bath.
Salisbury is in the southeast of Wiltshire, near the edge of Salisbury Plain. An ancient cathedral was north of the present city at Old Sarum. A new cathedral was built near the meeting of the rivers and a settlement grew up around it, which received a city charter in 1227 as New Sarum. This continued to be its official name until 2009, when Salisbury City Council was established. Salisbury railway station is an interchange between the West of England Main Line and the Wessex Main Line.
Stonehenge, a UNESCO World Heritage Site, is 8 miles (13 kilometres) northwest of Salisbury.
