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]
Frome (/ˈfruːm/ ⓘ, FROOM) is a town and civil parish in eastern Somerset, England. The town is built on uneven high ground at the eastern end of the Mendip Hills, and centres on the River Frome. The town lies about 13 miles (21 km) south of the City of Bath, with the market towns of both Westbury and Warminster sitting 6.5 miles to the East. It forms part of the parliamentary constituency of Somerton and Frome. The population was 28,559 in 2021.[1]
Frome was one of the largest towns in Somerset until the Industrial Revolution, and was larger than Bath from AD 950 until 1650. The town first grew due to the wool and cloth industry; it later diversified into metal-working and printing, although these have declined. The town was enlarged during the 20th century but retains a large number of listed buildings, and most of the centre falls within a conservation area.
The town has road and rail transport links and acts as an economic centre for the surrounding area. It provides a centre for cultural and sporting activities, including the annual Frome Festival and Frome Museum.
In 2014, Frome was named by The Times the "sixth coolest town" in Britain.[2] It was shortlisted as one of three towns in the country for the 2016 Urbanism Awards in the 'Great Town Award' category.[3] In its 2018 and 2021 report on the "Best places to live in the UK", The Sunday Times listed Frome as the best in the South West.[4] In April 2019, Time Out listed Frome among 15 of the best weekend breaks from London.[5]
