Plunge-cut grinding. The centerless plunge-cut grinding method entails grinding workpieces with offset or profiled diameters. Here, the grinding wheel is given the negative profile of the desired workpiece contour. In this way, all the diameters which have to be produced at the workpiece can be ground in a single plunge cut operation.

In-feed grinding — also called plunge grinding — is used to grind cylindrical parts with notches or complex shapes, such as gear shafts. Here, the workpiece rest blade needs to be tooled to match the shape of the part, and the grinding and regulating wheels must be dressed to match the part's desired profile cut.

The internal grinding is a high-speed operation, because the grinding wheel rotates at a speed of 30,000 rpm or even more. Internal grinding can be one of three types: traverse grinding, plunge grinding, and profile grinding [2]. Finally, centerless grinding is typically the same as cylindrical grinding.

You take your blade, apply it nice and flat to the belt, edge up, and grind toward your plunge cut, so that when you get there the belt rides over the platen edge and is actually grinding lightly on the flat and lightly on the inside of the plunge cut. You're then grinding the plunge …

Two broad categories of grinding action are recognized; one where negligible ploughing and rubbing take place and where the plunge velocity versus normal force intensity curve is a straight line through the origin, the other where ploughing and rubbing predominate and the plunge velocity versus normal force intensity curve is concave upward.

I am in dire need of some help from someone who has worked at W&S and knows the grinding centers produced in the late 70's and early 80's. I work for a company that has been around for over 90 years and one of our grinders passed away about two weeks ago. He worked here for over 40yrs and ran a Warner & Swasey Plungemaster Grinding Center.
