Facts About Centerless Grinding

Centerless grinding is an advantage in the machining industry due to its precise nature. Though not many people know much about it, we are here to give you a few facts about this machining process. 

Simple Yet Precise
Although centerless grinding sounds difficult, it’s actually very simple. For example, centerless grinders don’t have a lot of moving parts. The process involves the part being supported by a workpiece rest blade. Sitting between two rotating cylinders with either a regulating wheel (for the in-feed grinding) or linear travel (for through-feed grinding) of the part and a large, abrasive grinding wheel. 

Choice Between Through-Feed and In-Feed
There are two methods when dealing with the centerless grinding process.  For parts with consistent roundness across the length of it, through-feed is typically used. Now, the in-feed method is used to grind cylindrical parts that have complex shapes. 

The Wheel Matters Most 
With centerless grinding, the grinding wheel choice is the key factor. The wheel has to be suited to both the metal from the parts that are made and the surface finish one wants to achieve. The grinding wheels come in a variety of grain types and sizes.
