Centerless Grinding

Centerless Grinding

Centerless grinding is a fascinating process that achieves exceptional precision without the need for centers or chucks. Here, we explore the three primary forms of centerless grinding, each distinguished by the method used to feed the workpiece through the machine:

Through-Feed Grinding:

In this method, the workpiece is fed through the grinding wheels completely. It enters the machine on one side and exits on the other. Through-feed grinding is highly efficient and ideal for parts with simple, cylindrical shapes.

End-Feed Grinding:

Here, the workpiece is fed axially into the machine on one side and comes to rest against an end stop. End-feed grinding shines when dealing with tapered workpieces or those requiring precise shoulder grinding.

In-Feed Grinding:

In this technique, the workpiece rests on the work-rest blade, positioned between the grinding and regulating wheels. In-feed grinding is the go-to choice for parts with complex shapes and intricate contours.

No matter which grinding method best suits your parts, consider Danobat’s ESTARTA product line—designed and built by Danobat in Spain. These machines master all three processes with ease, ensuring precision, reliability, and excellence in every grind.
