In this article, you will learn exactly what centerless grinding is. Further, you will also learn what parts make up a centerless grinder. You will also learn exactly how these parts do their job in a centerless grinder. In particular, you will learn how these parts work in conjunction to prevent the piece being worked on from moving out of the cutting area on a centerless grinder.
If you do any type of metalworking, chances are you’ve probably heard of a centerless grinder. Conceptually and fundamentally, centerless grinders are probably the most misunderstood topic in metalworking. A centerless grinder does the same sort of material removal that a regular grinder does except for one huge difference, there is no spindle used in the process of centerless grinding. By using a centerless grinder, you can greatly increase your output. Centerless grinding will allow you to manufacture a lot of pieces in a short period of time.
Most people just can’t wrap their head around the concept of centerless grinding. It almost seems impossible for a centerless grinder to work the way that it does. At first blush, it’s completely understandable why centerless grinding is so confusing. One would believe that because there is no spindle holding the piece in place, the piece would just go where it pleases outside of the grinding zone. Despite the lack of a spindle, a centerless grinder will usually not allow the piece to get out of the grinding area. If you’re familiar with grinders, you already know that the material is held in place by a spindle or chucked and rotated against another grinding wheel which is rotating at a higher velocity. The other grinding wheel is usually powered by an external motor which is housed in the grinder’s workhead.
How does the centerless grinder work? The pieces worked on by using a centerless grinder will not require you to have holes in the middle, any type of driver, or a worked fixture. The piece you are working with is stabilized and held by a workblade. The work blades are placed in the middle of two other parts. The workblade is in the middle of a grinding wheel which turns at an extremely fast rate, and what is usually referred to as a regulating wheel. The regulating wheel turns at a slower rate than the grinding wheel turns at. The regulating wheel also turns within a more confined diameter than the grinding wheel does.
Hopefully, the concept of centerless grinding has been made a little more concrete. Centerless grinding is a very efficient way to get large amounts of pieces done in a short amount of time. If you want to do grinding effectively and efficiently without having to rely on a center spindle, then you should definitely look into a centerless grinder.
