Centerless ground bars are an essential part of many machining processes. By providing increased accuracy, reduced waste, and a smoother finish, centerless ground bars can help take your machining process to the next level. Are you interested in learning about the benefits of using centerless ground bars, and why they are essential to a successful machining process? This centerless ground bar supplier in Phoenix, Arizona is going to explain below.

A More Efficient Process

Centerless ground bars provide a much more efficient product for machining than using hot rolled or cold drawn bar. Unlike turning, milling, or hand grinding, centerless grinding is a much faster process that eliminates the need for multiple steps. It allows for precision cylindrical grinding of materials up to ten times faster than other methods, enabling manufacturers to reduce lead times and increase production rates.

This process also allows for a high degree of automation, leading to greater cost savings and improved productivity. The entire process can be completed by your centerless ground bar supplier in Phoenix, Arizona providing you with material produced by one of the most efficient and cost-effective methods available. 

Greater Dimensional Accuracy

When machining metal bars, the goal is to produce pieces that meet your exact dimensional specifications. To achieve this, you must start with a material that is as precise as possible. Centerless ground bars offer superior dimensional accuracy, allowing you to begin with a material that is closer to your finished dimensions from the start.

Centerless grinding ensures that the material is of uniform diameter throughout its entire length, removing any inconsistencies or irregularities. This is especially beneficial for longer bars since it eliminates the possibility of having different diameters at each end or throughout its length.

Additionally, centerless ground bar suppliers in Phoenix, Arizona can produce a product that has tighter tolerances and a more consistent surface finish than other bar products. This ensures that your machined parts will be consistently accurate and of a higher quality.

Smoother Surfaces

Another one of the key advantages of using centerless ground bars for machining is that the process produces a smoother surface than regular hot rolled or cold drawn bars. This smoothness is attributed to the fact that when a bar is machined with a centerless grinding process, it is subject to less metal deformation. This, in turn, reduces the risk of residual stresses being left on the surface, resulting in fewer imperfections on the finished part.

The combination of this smoother surface finish and the higher precision capabilities of centerless ground bars makes them ideal for applications that require parts with tighter tolerances and higher performance. Furthermore, because the parts are subject to less stress during the manufacturing process, they are often less prone to fatigue failure, which improves their durability and reliability.

Increased Strength and Hardness

Your centerless ground bar supplier in Phoenix, Arizona can heat treat the bars to further increase their strength and hardness. This heat treatment process adds to the bar’s already higher strength and hardness, resulting in a strong and durable product.

With the increased strength and hardness, centerless ground bars are suitable for use in precision parts such as valves, automotive components, and medical devices. The high strength and hardness also help improve the product’s overall performance.

Final Thoughts

Centerless ground bars are essential to many successful machining processes, offering several advantages over traditional methods. They provide a more efficient process with greater dimensional accuracy, tighter tolerances, and smoother surfaces.
