When to Choose the Centerless Grinding Method

When it comes to the refining and finishing of metal parts and components, there are several specialized grinding methods you can apply to your workpiece. Thread grinding, ID grinding, OD grinding, and centerless grinding solutions are all common examples of methods used in the metal fabrication process for various metal parts and components. With the right grinding services partner, you will be able to determine the right method for your unique needs. Here are some of the top product types fabricated using the centerless grinding technique, and some of the major benefits to applying this technique.


So how does the centerless grinding process work? The entire process can be simplified into 4 main parts: The workpiece itself, the work rest component for holding the workpiece in place, the grinding wheel, and the regulating wheel.


As you likely assumed or guessed, the grinding wheel is the main actor in the centerless grinding process. The grinding wheel rotates in a downward direction on a fixed axis, at a higher linear speed than the workpiece upon initial contact. The regulating wheel then acts as a stabilization component, applying opposite lateral force, with a rubberized or rough abrasive surface for maximum hold.


When using the centerless grinding technique, there are 3 general approaches: Through-feed, in-feed, and end-feed. Through feed involves sending the workpiece all the way through the grinding wheel, effectively grinding the entire part or component. Through-feed grinding is especially effective for single-size diameter parts, with high volume demands.


The in-feed centerless grinding technique is most-often utilized for workpieces with complex designs and abnormal shapes. This process involves the manual loading of the workpiece and direct movement/control over the regulating wheel.


Finally, end-feed centerless grinding primarily focuses on metal products where one end requires significantly different measurements than the other. This process works much like the through-feed technique, with an end-stop put in place to limit how much of the workpiece you can fabricate. This is often utilized for producing tapered products.
