The Best of Through-feed Centerless Grinding

Through-feed centerless grinding is often applied in grinding round bars and parts, particularly in the largest outside diameter of the material.



Bars? Tubes? Pistons? These are all achieved by centerless grinding machining solutions with through-feed grinding.

Through-feed grinding is often applied in grinding round bars and parts, particularly in the largest outside diameter of the material – a cylindrical process that guarantees an exceptionally high level of economic efficiency and productivity.

Through-feed centerless grinding is one of the most common but effective form of cylindrical grinding operations. It is typically used in grinding and cutting long bars and tubes which are typically used for automotive and engine applications.

The Through-feed Process

If the application requires machining and grinding large quantities of long and round and/or thin components and parts, there is no other considered alternative machining operation aside from through-feed centerless grinding. This best explains why centerless grinding is considerably the best technique of performing multiple tasks which include polishing and roughing – all done through a single pass!

Through-feeding Techniques

Through-feed grinding is performed through tilting the horizontal axis of the regulating wheel. Thus, centerless grinding can regulate the feed rate of the workpiece during this operation. The workpiece or the bar is fed into the grinding wheel and the regulating wheel. There is a continuous motion of entering the bar to the other side and flying out of the opposite side. The regulating wheel pulls the workpiece past the grinding wheel which is constantly dressed with abrasive grains.

The grinding machine typically consists of the grinding wheel, regulating wheel, and workblade makes it possible for the whole operation to achieve high level of productivity and machining efficiency. The workblade supports the bar/ workpiece in place, holding it in its proper height between the grinding and regulating wheels. The placement of the workpiece and the gap between the wheels is highly crucial to the diametrical tolerance, straightness, and roundness of the workpiece. But having the wheels placed in a controlled gap makes it possible for achieving that precision roundness and diameter tolerance among bars and tubes in large sizes and length.

The through-feed centerless grinding however, cannot be used in workpieces that have complicated geometric figures such as gear shafts and camshafts. Through-feed technique is often applied in parts with simple cylindrical shapes including tubes, piston, piston pins, and bars.

Through-feed grinding is often applied in grinding round bars and parts of material. And if you have a stock of round bars and tubes that need to be ground, Contact Us or Get our Free Quote so we could assist to your requirements!
