Precision grinding is an important and highly specialized machining process, one that requires particular equipment and a machine shop with experienced, well-trained personnel. Any time a project needs custom parts manufactured to within very tight tolerances, it’s likely that precision grinding will come into play.

But what goes into the precision grinding process, and what sort of equipment is used to meet the precise specifications demanded? Below, the Cincinnati-based R. A. Heller Co., one of the Midwest’s most trusted machine shops for over 70 years, explains how precision grinding works.

What Is Precision Grinding?

Exacting Fabrication

Simply put, precision grinding is a machining process whereby parts are fabricated and finished to meet extremely precise measurements. Precision grinding is often required for projects in which a particular part will not perform its function appropriately unless it is finished to exactly the correct parameters.

Techniques

Depending upon the needs of client and the specifications of the parts involved, experienced machining technicians may apply various techniques:

• Centerless Grinding: The workpiece is held between two wheels to efficiently remove material from both sides.
• Blanchard Grinding: Material is removed by a rotary grinder from just one surface of the work piece.
• Cylindrical Grinding: Material is removed from the outside diameter (OD) typically between centers.

Machinery

A high-quality machine shop will employ specialized equipment with measured capabilities to perform each of these techniques. R. A. Heller Co., as an example, has eight cylindrical grinders, centerless grinders that can accommodate pieces up to three inches in diameter and 12 feet long, and Blanchard grinding capabilities for workpieces up to 36 inches in diameter and 12 inches in height. Employing versatile equipment allows machining professionals to meet a wide range of specifications with unfailing precision.
