Truing operations deal with the form or profile of the grinding wheel. When truing a new abrasive wheel, the grinding face is altered to allow the abrasive product to do what it needs to do. Routine truing during the grinding process corrects the wheel profile and compensates for form loss as the wheel breaks down under regular use.
The correct term is rotary surface grinding or just rotary grinding. Whatever you call it, rotary grinding was first commercialized in the early 1900s. And for the reasons you're about to hear, it soon became the go-to technology for anyone needing smooth, accurate metal, glass, and ceramic parts. Rotary Grinding Basics
Precision grinding is the process of removing metal from a workpiece to achieve a specific size, shape, or surface finish. Surface grinding is a type of precision grinding that is used to create flat surfaces on metal workpieces. This process involves using a grinding wheel to remove tiny bits of material from the surface of the workpiece until it is smooth and flat.

PRG-DX grinders are highly productive by design. The wheelhead only needs to travel half of the rotary table diameter for full contact grinding. It's ideal for single or multiple workpiece grinding. They're perfect for high production precision work.
High-efficiency precision grinding can shorten the machining cycle of aspheric optical elements by a factor of 2–10. To achieve this objective, ultrasonic vibration (UV)–assisted grinding (UVG) has been increasingly applied to manufacture aspheric optics. However, the mechanisms of material removal and surface formation in UV …

or confirmed prior to attempting to grind. The following is a general set-up procedure for a rotary feed machine: 1. The face of the rotary hub is the starting point and should have no more than .0002" TIR. Mount a straight edge to the rotary hub, extended through the hood into the grinding zone across the entire diameter of the grinding wheel. 2.
13 Grinding 13.1 Definition Grinding is a metal cutting procedure in which a multi-edged tool, whose cutting edges are geometrically undefined, removes the chips. During grinding, the tool carries out the cutting motion. The cutting speeds com-monly used in grinding are approximately 20 times those used in turning (25 to 45, sometimes up to 120 ...
