Cylindrical Grinding

Cylindrical grinding is a precision finishing process used to achieve tight diameter control, excellent roundness, and superior surface finish on rotational components. It is a critical operation for shafts, pins, sleeves, bushings, and other cylindrical parts that require micron-level accuracy and stable performance.

At EadeTech, cylindrical grinding is applied to titanium alloys, nickel-based superalloys, hardened steels, tungsten, molybdenum, and precision engineering metals, supporting aerospace, medical, automotive, electronics, and industrial applications.


What Is Cylindrical Grinding?

Cylindrical grinding uses a rotating abrasive wheel to remove material from the external or internal diameter of a workpiece while it rotates between centers or in a chuck. Unlike turning, grinding enables much tighter tolerances and finer surface finishes, especially after heat treatment or stress-relief processes.

Key advantages include:

  • Excellent roundness and concentricity

  • Very tight diameter tolerances

  • Smooth surface finish for functional contact surfaces

  • Minimal thermal and mechanical distortion


Why Cylindrical Grinding Is Essential for Special Materials

Advanced alloys often present challenges such as:

  • Work hardening during turning

  • Dimensional drift after heat treatment

  • Surface integrity issues on bearing surfaces

Cylindrical grinding resolves these issues by allowing controlled, low-force material removal, making it ideal for aerospace shafts, medical components, and precision industrial parts.

Quality Control & Inspection

Every cylindrical ground part is subjected to strict inspection to ensure performance and reliability:

  • CMM and roundness measurement

  • Diameter and concentricity verification

  • Surface roughness testing

  • Visual inspection for burns or chatter
