Double Disc Grinding Services

Double disc grinding is an effective means of grinding two-dimensional metal parts to uniform flatness and parallelism on both sides. In double disc grinding, the workpiece passes between two grinding wheels, contacting their flat sides rather than their faces. The twin grinding wheels remove material on both sides of the workpiece. The mechanics of these processes also create a randomized “arcing” pattern on the surface of the part, which is sometimes used for decorative purposes.

Petersen Precision offers a variety of double disc grinding services, all utilizing automated horizontal spindle grinding technology to maintain superior precision, accuracy, and high throughput. With our precision double disc grinding capabilities, we can maintain thickness tolerances up to ±0.0002” and achieve surface finishes as low as 8 RMS.

Considerations to Keep in Mind for Your Double Disc Grinding Project

There are several considerations to keep in mind when using double disc grinding. Factors such as material choice, level of surface finish, flatness, and required tolerance will determine the type of grinding media and cutting wheels we use to ensure your expectations are met. We employ two double disc grinding methods depending on the unique needs of your project:

  • Pass-through double disc grinding is most commonly used to meet final or pre-final thickness requirements for fine blanked parts and to provide a consistent surface finish and uniform parallelism on both sides. Fine blanks tend to have one sharp edge and one rolled edge, and double disc grinding is an effective way to remove these feature variations.
  • Paddle grinding and stroker grinding are used to achieve very high tolerances and precision surface finishes on all types of flat metal parts.
