Centerless grinding has been known to achieve perfect roundness and dimensional tolerance, but it also offers other advantages essential in meeting high production volumes.
For years, centerless grinding has been known to have surpassed the previous norms of metalworking, and demand for centerless grinding has continued to increase in a number of industries. It is clear that this machining solution is effective, as it allows manufacturers to achieve smoother surface polishes, bring out tighter dimensional tolerances, and hold even higher degrees of straightness in their parts.
But those are not the only advantages presented by centerless grinding, and other benefits include the following:
1. No room for deflection
The workpiece is rigidly supported by the regulating wheel, which presses it to the abrasive grains on the grinding wheel. It is well supported under the grinding cut and for the full length of the cut. Thus, there’s no room for deflection to occur in the process. This has also allowed heavier passes other than grinding between centers.
With preventive maintenance (PM) you can optimize production. Ensuring proper maintenance as part of your operation, along with keeping the proper equipment and tools will make a huge difference in the production of materials and the quality of the result. In order to make sure to avoid deflections while meeting daily production volumes without a glitch, a quick fix and regular machine inspection is key!
2. Ability to grind brittle materials and distorted parts
In centerless grinding, there is no axial thrust imposed on the workpiece during grinding which results in the ability to grind different sizes and geometrical figures. It is possible for the centerless grinder to grind long pieces of brittle materials, and even distorted parts, due to the absence of the end pressure.
3. Short loading time
The short loading time allows for a continuous process compared to grinding between centers. As the name implies, there is no need to support the workpiece in the center. The workpiece goes directly into a “through-grinding” process. The work blade simply holds the workpiece in place and at the correct height, which is critical to achieving the desired diameter tolerance and roundness of the bar material.
4. Grind large quantities
Centerless grinding can essentially be used in working any size workpiece. Tools like gravity chutes, hopper feeders and magazines are used to adapt the mechanism to different part sizes.
5. Longer yield/ wheel life
Because there is no need for centering, no external feeding mechanism is needed. A true floating condition occurs during the process, which results in a longer wheel life/yield and less stock needed. A coolant is poured out onto the wheels to control the heat during the process
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.
