What is External Cylindrical Grinding?

2023-05-18

External Cylindrical Grinding is a precision machining process used to shape the outer surface of a cylindrical workpiece. It is a common method employed in manufacturing industries to achieve high dimensional accuracy, surface finish, and tight tolerances for various cylindrical components.

Precision Grinding

In external cylindrical grinding, a cylindrical grinding wheel rotates at a high speed and removes material from the workpiece to create the desired shape and surface finish. The workpiece, which is typically made of metal, is held in place between centers or in a chuck and rotated against the grinding wheel.

The grinding wheel is composed of abrasive particles bonded together, and it is chosen based on the specific requirements of the job, such as the material being ground, the desired finish, and the level of precision needed. The grinding wheel may be made of various abrasive materials, such as aluminum oxide, silicon carbide, or cubic boron nitride (CBN).

During the grinding process, the grinding wheel traverses along the length of the workpiece, removing material in small increments. This can be achieved by moving the workpiece or the grinding wheel or a combination of both. The depth of cut is controlled by adjusting the infeed of the grinding wheel.

Precision Grinding External cylindrical grinding can be performed using different grinding methods, such as plunge grinding, traverse grinding, or oscillating grinding, depending on the specific requirements of the workpiece and the desired results.

External Cylindrical Grinding

This Grinding Service is commonly used to produce cylindrical components with high precision, such as shafts, rods, spindles, cylinders, and other similar parts. It allows for the production of parts with tight tolerances, excellent surface finish, and precise geometrical features, making it suitable for applications where accuracy and quality are crucial, such as in the automotive, aerospace, and tooling industries.
