Through-feed centerless grinding is often applied in grinding round bars and parts, particularly in the largest outside diameter of the material.
Bars? Tubes? Pistons? These are all achieved by centerless grinding machining solutions with through-feed grinding.
What is Through-Feed Grinding?
Through-feed centerless grinding is one of the most common and effective forms of cylindrical grinding operations. It is typically used in grinding and cutting long bars and tubes, typically used in automotive and engineering applications.

Through-feed grinding is often applied in the grinding of round bars and parts, particularly in the largest outside diameter of the material – a cylindrical process that guarantees an exceptionally high level of economic efficiency and productivity.
Through-feed grinding Process
If the application requires machining and grinding large quantities of long and round and/or thin components and parts, there is no comparable alternative to through-feed centerless grinding. This is why centerless grinding is considered the best technique for performing multiple tasks including polishing and roughing – all done in a single pass!

Through-feed grinding Techniques
Through-feed grinding is performed by tilting the horizontal axis of the regulating wheel. Thus, centerless grinding can efficiently regulate the feed rate of the workpiece during this operation. The workpiece, or bar, is fed into the grinding wheel and the regulating wheel. There is a continuous motion of bars entering one side and flying out of the other. The regulating wheel pulls the workpiece past the grinding wheel which is constantly dressed with abrasive grains.
The grinding machine typically consists of the grinding wheel, regulating wheel, and work blade, making it possible for the whole operation to achieve high levels of productivity and machining efficiency. The work blade supports the bar/ workpiece, holding it in its proper height between the grinding and regulating wheels. The placement of the workpiece and the gap between the wheels is crucial to the diametrical tolerance, straightness, and roundness of the workpiece and having the wheels placed in a controlled gap makes it possible to achieve precision roundness and diameter tolerance with bars and tubes of large sizes and lengths.
The through-feed centerless grinding, however, cannot be used in workpieces that have complicated geometric figures such as gear shafts and camshafts. The through-feed technique is often applied in parts with simple cylindrical shapes including tubes, pistons, piston pins, and bars.

The Basics of Aluminum Alloy
Aluminum is the most abundant metal in Earth’s crust after silicon and oxygen. It has a silvery-white appearance and contains a lot of valuable mechanical properties. It possesses 60% of the electrical conductivity of copper, with much lower density, making it a lightweight material perfect for aircraft and aerospace construction.
Pure aluminum is soft and ductile, but it can be strengthened when it is alloyed with other elements like magnesium, copper, and silicon. Such alloys possess better corrosion resisting properties, with a protective oxide coating that is achieved and enhanced through the process of anodization. Their lightweight and non-toxic mechanical properties enable them to be easily machined and cast. One good thing about aluminum is that it is recyclable, which can save considerable amounts of energy. They only need to undergo a melting process in order for them to be reused.
Powerful Properties
Aluminum alloys have low density, therefore, they are lightweight which is one of the key factors to consider in constructing an aircraft and its vital parts. Other important properties they possess are malleability, high strength, easy machining, good electrical and thermal conductivity, and excellent corrosion resistance.
Aluminum in the Aviation Industry
80 percent of commercial transport aircraft frames are made up of aluminum. This alloy is the top choice for the construction of aircraft and parts like wings and fuselage. Most navy aircraft are mainly made of fabricated aluminum. The focus on aluminum casting technology is continuing to earn recognition with its countless advantages in forming complex parts for aircraft structure. With a low manufacturing cost, Aluminum Alloy is the top choice for incorporating innovative and complicated design concepts in the aviation industry.
