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]
Huddersfield is a town in the Metropolitan Borough of Kirklees in West Yorkshire, England. It is the administrative centre and largest settlement in the Kirklees district. The town is in the foothills of the Pennines. The River Holme's confluence into the similar-sized Colne is to the south of the town centre which then flows into the Calder in the north eastern outskirts of the town.
The rivers around the town provided soft water required for textile treatment in large weaving sheds; this made it a prominent mill town with an economic boom in the early part of the Victorian era Industrial Revolution. The town centre has much neoclassical Victorian architecture. An example is its railway station, which is a Grade I listed building described by John Betjeman as "the most splendid station façade in England".[2] It won the Europa Nostra award for architecture.
Huddersfield hosts the University of Huddersfield and three colleges: Greenhead College, Kirklees College and Huddersfield New College. The town is the birthplace of rugby league with the local team, Huddersfield Giants, playing in the Super League. It also has a professional football team called Huddersfield Town, that currently competes in the Championship, as well as two Rugby Union clubs Huddersfield R.U.F.C. and Huddersfield YM RUFC. Notable people from the town include two-time British Prime Minister Harold Wilson (for Labour) and film star James Mason were born in the town.
The town has been classed under Yorkshire, the West Riding of Yorkshire and West Yorkshire for statistics throughout its history. The town's population in 1961 was 130,652 with an increase to 162,949 at the 2011 census; it is in the West Yorkshire Built-up Area.[3][4] The town is 14 miles (23 km) south-west of Leeds, 12 miles (19 km) west of Wakefield, 23 miles (37 km) north-west of Sheffield and 24 miles (39 km) north-east of Manchester.
