Centerless grinding is similar to all machining processes because the process mainly consists of cutting metal. This grinding process, however, involves an abrasive cutting action.
What It Takes To Execute The Grinding Process
The centerless grinding process can seem quite similar to most other machining and metalworking processes but unlike any other process, which typically require one or two cutting edges, centerless grinding employs thousands of cutting grains to grind the bar material that is fed between the two wheels.
Essentially, a bar of material is fed in the centerline between the grinding wheel and the regulating wheel.
The grinding wheel, which is responsible for the grinding process itself, consists of many abrasive cutting grains on its surface, which grind the bar material until it reaches perfect roundness. During the process, the grinding wheel loses some of the abrasive grains, so it must be constantly dressed with new cutting grains to achieve the perfect shape and surface every time.
The regulating wheel, on the other hand, applies a lateral pressure to the workpiece as it turns and moves upward against the grinding wheel. As a movable wheel, the regulating wheel is not responsible for cutting the bar material. Its job is merely to press the bar into the grinding wheel and to control the speed of its rotation.
How To Complete The Grinding Action
To complete the action, the work blade (made of carbide-tipped steel) must support and hold the bar material in position, above the centerline and between the grinding wheel and the regulating wheel. The rotation process releases much heat, so the presence of a flowing fluid cooling agent is highly necessary to avoid unintended hazards.
From the series of processes, one could really infer how important it is to consider the basic fundamentals and rules of the operation beforehand. In the process of selecting the proper tools and equipment for this machining process, the hardness of the material should be taken into account to determine what specific type of grinding wheel should be used.
To get started with the metal grinding process, the work blade must be set first hand since it is responsible for the control of the workpiece and its height above the centerline of the wheels which will determine the grinding operations.

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.
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.
