>Workholding for Cylindrical Grinding - Canadian Metalworking
Instead of feeding the workpiece through the grinder, the part is located against a stop and a specially dressed wheel is traversed into the part, crush-grinding the profile on the workpiece. This process generally is used for high volumes, as the grinding wheels used are large and expensive, and custom dressing them is time-consuming.

>What is Profile Creep Feed Grinding and how does it work?
Grinding wheels with vitrified bonds are usually dressed with profile rollers that correspond to the finished workpiece profile. Materials that are difficult to machine, such as nickel-based superalloys like those used in aerospace jet engines, can today be economically processed with electroplated or vitrified CBN grinding wheels.
>Optimization of the Gear Profile Grinding Process ...
As a good first example, a grinding process with a constant stock ∆s along the profile was chosen. This is a typical process occurring in single-flank grinding with an in-feed realized by the rotation of the workpiece. The stock amounts to ∆s = 0.1 mm constantly along the profile geometry. The radial infeed a e

>What is Cylindrical grinding? - precision-surface
In centerless grinding the workpiece is fixed by 3 points. This fixation is determined by the components grinding wheel, control wheel and support ruler. The workpiece is simultaneously guided and machined on the periphery. In centerless plunge grinding, the grinding wheel moves radially towards the workpiece.
>Centerless Grinding Introduction, Advantages, And ...
The workpiece can have an independent outer diameter over the entire length, and the improved grinding wheel can be used to grind each part of the workpiece or crush the entire workpiece. Plunge feed can do feed centerless grinding, so any profile can be produced.

The G-H series is a range of versatile universal profile grinding machines, particularly suited to gear and shaft grinding applications, and these machines also come in the GX version for longer workpiece requirements. The GT 500 H combines all profile and continuous generating grinding processes with the most avant-garde tooling technology around.
>Cutting Tool Applications, Chapter 17: Grinding Methods ...
The rotation of the grinding wheel pushes the workpiece down on the workrest blade and against the regulating wheel. The regulating wheel, usually made of a rubber-bonded abrasive, rotates in the same direction as the grinding wheel and controls the longitudinal feed of the work when set at a slight angle. By changing this angle and the speed ...
