Achieving extremely precise roundness with very tight tolerance is a walk in the park with our advanced centerless grinding solutions
As the demand for closer tolerances on bar diameters and finer surface finishers increases, Advance Grinding Services, Inc. continually performs. The use of advanced CNC machines is true to many purchasing precision ground bars, so we ensure tight diameter tolerance and super-fine surface finishes in every bar and product.
Centerless ground bars have can have a tolerance up to .0001” and a very fine micro finish. The perfectly ground and polished bar can even be achieved in out-of-round material, through a rigid process during the grinding operation. Three-point gages are used to ensure the workpiece in its proper place and in the proper hold. Bars may be cold-drawn before being ground to meet customers’ demand for specific finished physical properties.
Our metal operators always consider the following factors in grinding centerless ground bars:
- Internal structure
- Depth of decarburization
Considering factors of setting up the wheel is also very important to bring out a perfect product
1. Proper distance between the grinding wheel and the regulating wheel
As a three-point positioning method used in the process, the proper distance between the wheels is a must! This will provide bar size consistency and accurate surface finish in every workpiece.
2. Regular grinding wheel dressing
The faulty dressing can lead to uneven fine lines or wavy traverse lines, leaving ragged wheel edges. Diamond dressed wheels should be maintained at an even rate. Due to the thorough grinding, grains become dull and so wheels should be redressed at times.
3. Type of abrasive grains
Diamond grains are best recommended in the grinding process since diamonds are sharp and hard to break. They should not be allowed to dwell on the wheel and should be dressed across the face of the wheel only, starting at the edge.
4. Location of the workpiece between wheels
The workpiece must be placed properly in the process and in proper hold between the wheels. The location of the workpiece is critical in achieving that perfect grinding process.
5. Proper Implementation of work support blades
Choose the proper work blades for your process. Change the blades to the softer material. It is best to use steel, aluminum bronze, or cast iron.
The process of meeting the correct tolerance and surface finish in all bar products is thoroughly monitored in each phase of operation. Proper surface grinding can easily be achieved with an understanding of basic fundamentals of grinding – and in that, we excel in all our 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.
