Holding Proper Control For Precision Centerless Grinding

Acquiring that precise roundness and tight tolerance is all possible as long as proper control and support is always implemented.

When it comes to centerless grinding, all these words come following up: multifunctionality, precision roundness, tight tolerance, perfect polish, and excellent surface finish. But how do all these come to effective result?

High volume production is commonly the field for this kind of machining operation. For grinding long round bars, like that of thrufeed centerless grinding operation, a simple support of the workpiece is not sufficient for an effective operation. Bars with approximate weight of 450 lbs or even more, cannot be possibly brought into the high rotational speed to acquire the required finish. The regulating wheel, which imparts a traverse movement and pulls the workpiece past the grinding wheel could not handle much weight if the support implemented isn’t firm.

Supporting Rollers

Grinding of a workpiece using through feed/thrufeed grinding uses attached stands with guide rollers in supporting ingoing and outgoing workpiece. Yet, in a heavy machining course, the use of support tables and supporting rollers is highly important. These rollers turn at a rate in which it will impart a peripheral speed to the rotating workpiece same to that of regulating wheel. The regulating wheel though, is not responsible for part cutting but the grinding wheel.

In addition, the proper placement and adjustment allows grinding long bars and even complex parts like out-of-round materials and smallest diameter to be ground to their required diameter cut.

Superabrasive Wheel

Right after you have implemented the proper preventative maintenance, sure you’ve got the full control for your operation to keep running in a smooth flow. And this also involves a quick check on your machine which involves the support and of course, the wheels. They take a bite on the surface and cut away the unnecessary parts of the material.

A constant dressing of abrasive teeth on the wheel’s surface is an essential part of superabrasive optimum grinding. These abrasive grains dressed on the surface of the wheels are responsible for grinding bar surface, which also includes these important tasks: cleaning, polishing, roughing, and finishing.

Proper Control and Placement

The gap between the grinding wheel and the regulating wheel is highly critical to the surface finish and polish of the bar. It must be that the workblade is placed just in the proper height including the workpiece (bar) for this will significantly affect in achieving precise roundness and tight tolerance of the bar.

This kind of process makes the machine capable enough of doing any type of cylindrical grinding operation such as through feed centerless grinding and in-feed centerless grinding.

Centerless grinding is actually a production machining process. And if you’re running a high volume bar production, talk to us and we’ll give the best machining solutions for you!
