Chapter 3: Grinding Geometry and Kinematics | …

 · Material removal by grinding occurs mainly by a chip formation process, similar to that of other machining methods such as turning or milling, but on a much finer scale. While the cutting-tool geometry and its interaction with the workpiece is well defined for most machining processes, the situation for grinding is not readily discernible.

Eliminate Grinding Through Rotational Turning …

Rotational turning technology eliminates the need for grinding because of special kinematics between the rotating workpiece and a rotating tool that creates a twist-free surface on a turning machine. The result is, compared with conventional machining rotational turning allows a reduction in machining times of more than 70 percent, with higher process reliability and longer tool life.

Cylindrical grinder

The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft.
