What Is Cylindrical Grinding？
Cylindrical grinding is a precision process where a rotating cylindrical workpiece is ground against a high-speed grinding wheel to achieve smooth surfaces, close tolerances, and precise geometry. This method refines the outer (OD) or inner diameter (ID) of metal parts, ensuring roundness and high-quality finishes. The workpiece is secured on a spindle or chuck, and controlled wheel movement allows for fine finishes and exact dimensions. Commonly used in manufacturing, cylindrical grinding produces components like shafts, rods, and bearings that require accurate roundness and superior surface quality.
Our grinding operators are highly experienced and familiar with machine parameters, allowing them to achieve high-quality surface finishes. Our grinding services, combined with other CNC processes, enable us to produce parts with excellent precision and surface finish according to your requirements, enhancing your profitability.
Cylindrical Grinding Processes：
-
OD Grinding
In OD (Outer Diameter) grinding, the workpiece rotates against a grinding wheel to refine its external surface. This process is specifically used to achieve precise finishes on the outer diameter.
-
ID Grinding
ID (Inner Diameter) grinding focuses on the internal surfaces of a workpiece. A grinding wheel is inserted inside, and the material is precisely removed as the wheel and workpiece rotate in opposite directions, perfecting the internal diameter.

FAQ
Yes, cylindrical grinders can process non-cylindrical shapes, such as ovals, cams, and crankshafts. By adjusting the rotation axis and specific settings, they achieve precise grinding of complex shapes.
Cylindrical grinding is ideal for high-precision parts, including automotive components like transmission shafts and engine parts, aerospace turbines and bearings, energy sector compressor parts, medical prosthetics, and machine manufacturing items like spindles and tool supports.
Common cylindrical grinding types include external diameter (OD) grinding and internal diameter (ID) grinding. OD grinding is used for the outer surface of parts, while ID grinding is for internal surfaces. There’s also centerless grinding, which allows for continuous processing as the part is held between wheels.
The main difference lies in the workpiece and support method. Cylindrical grinding involves rotating both the grinding wheel and the workpiece, typically secured at its ends with a spindle or chuck.
In contrast, surface and wheel grinding create flat or contoured surfaces, with the workpiece remaining stationary on a magnetic chuck (for ferrous materials), a vacuum chuck, or other fixtures.
