What are the precision requirements for CK45 Chrome Plated Round Bar in precision machinery?

Oct 29, 2025

Precision machinery demands components that meet exacting standards to ensure optimal performance and reliability. Among these components, CK45 Chrome Plated Round Bars play a crucial role. As a supplier of CK45 Chrome Plated Round Bars, I understand the significance of precision requirements in precision machinery applications. In this blog, I will delve into the key precision requirements for CK45 Chrome Plated Round Bars in precision machinery and explain how our products meet these standards.

Dimensional Precision

One of the primary precision requirements for CK45 Chrome Plated Round Bars in precision machinery is dimensional accuracy. The diameter, length, and straightness of the round bar must adhere to tight tolerances to ensure proper fit and function within the machinery. Even the slightest deviation from the specified dimensions can lead to issues such as misalignment, increased friction, and premature wear of components.

For example, in a hydraulic system, the CK45 Chrome Plated Round Bar serves as a piston rod. Any variation in the diameter of the rod can affect the sealing performance of the hydraulic cylinder, leading to leakage and reduced efficiency. Therefore, we ensure that our CK45 Chrome Plated Round Bars are manufactured with high-precision machining processes to achieve the required dimensional accuracy. Our state-of-the-art equipment and quality control measures allow us to maintain tight tolerances, typically within ±0.01mm for diameter and ±0.1mm for length.

Surface Finish

The surface finish of CK45 Chrome Plated Round Bars is another critical precision requirement in precision machinery. A smooth and uniform surface finish is essential to reduce friction, prevent corrosion, and improve the overall performance of the machinery. In precision applications, such as in the aerospace and automotive industries, the surface finish of the round bar can significantly impact the efficiency and reliability of the equipment.

We use advanced chrome plating techniques to achieve a high-quality surface finish on our CK45 Chrome Plated Round Bars. The chrome plating not only provides a hard and wear-resistant surface but also enhances the corrosion resistance of the round bar. Our plating process ensures a smooth and uniform surface finish, with a surface roughness (Ra) typically less than 0.4μm. This smooth surface finish reduces friction between the round bar and other components, resulting in improved efficiency and longer service life.

Hardness and Wear Resistance

In precision machinery, CK45 Chrome Plated Round Bars are often subjected to high loads, pressures, and friction. Therefore, they must have sufficient hardness and wear resistance to withstand these conditions without deformation or excessive wear. The hardness of the round bar is determined by the material composition and the heat treatment process.

We use high-quality CK45 carbon steel as the base material for our round bars. CK45 steel has good mechanical properties, including high strength and toughness. After the chrome plating process, we perform a heat treatment to further enhance the hardness and wear resistance of the round bar. Our heat treatment process is carefully controlled to ensure that the round bar achieves the desired hardness, typically between 50-60 HRC. This high hardness and wear resistance make our CK45 Chrome Plated Round Bars suitable for use in demanding precision machinery applications.

Straightness and Concentricity

Straightness and concentricity are also important precision requirements for CK45 Chrome Plated Round Bars in precision machinery. A straight and concentric round bar ensures smooth operation and accurate positioning of components within the machinery. Any deviation from straightness or concentricity can cause vibration, noise, and premature wear of components.

We use advanced straightening and grinding processes to ensure the straightness and concentricity of our CK45 Chrome Plated Round Bars. Our straightening equipment can correct any minor bends or deviations in the round bar, ensuring that it meets the required straightness tolerance, typically within ±0.05mm/m. The grinding process is used to achieve a high degree of concentricity, with a concentricity tolerance typically within ±0.01mm.

Our Product Range
