Semi-Automatic & Universal OD Grinding

Versatile Grinding for Large and Small Parts with Tight Tolerances

What Is Semi-Automatic & Universal OD Grinding?

Semi-automatic OD (Outside Diameter) grinding is a process where the external surface of a cylindrical workpiece is ground to precise dimensions and surface finish, using a machine that automates some—but not all—process steps. In semi-automatic OD grinding, the machine performs grinding operations automatically, but an operator is still required to set up the part, load and unload the workpiece, and sometimes initiate or monitor certain functions.

Semi-Automatic & Universal OD Grinding: Flexibility for Custom Low and Moderate Production

At CPG, our semi-automatic OD grinding services can grind parts up to 10” in diameter and 72” in length.

Our six versatile machines allow for flexible setups, making them ideal for both small, custom orders and high-production runs.

Your parts will meet the necessary tolerances and finish quality across both prototype and production work.

Is CPG’s Semi-Automatic & Universal OD Grinding Right for Your Application & Industry

These grinders are ideal for low-volume, high-complexity runs and for industries that need custom grinding solutions on a variety of part sizes. Semi-automatic OD grinding is widely used in industries where moderate production volumes and high precision are required, such as:
