Commonly used to grind cylindrical surfaces or the shoulders of workpieces, the method is capable of great precision: Tolerances from ±0.0005" (13 μm) to ±0.00005 inches (1.3 μm) for diameter. Tolerances from ±0.0001" (2.5 μm) to ±0.00001 inches (0.25 μm) for roundness. Typical finishes from 8 µin (0.20 μm) to 32 µin (0.81 μm)
1. Center type cylindrical grinding: is a process for grinding the end faces of a cylindrical workpiece. Center type cylindrical grinding is one of the most common operations in precision machining. It is used to grind and polish the ends of cylinders, tubes, and other round parts to a desired diameter or surface finish. 2.
To improve the performance of conventional cylindrical plunge grinding processes, this paper introduces parallel grinding which employs an extra grinding wheel opposite to the original one, simultaneously cutting workpiece. Depending on the relative location of the two wheels, the cutting areas are divided into non-overlapped and overlapped zones. In the …
Process. A cylindrical grinder has a grinding (abrasive) wheel, two centers that hold the workpiece, and a chuck, grinding dog, or other mechanism to drive the work. Most cylindrical grinding machines include a swivel to allow for the forming of tapered pieces. The wheel and workpiece move parallel to one another in both the radial and longitudinal directions.

Grinding is a machining process that utilizes an abrasive grinding wheel to remove material. Grinding parts, whether cylindrical or prismatic in shape, creates superior surface finishes and extreme accuracy in features of size. While there are many grinding methods available, two of the most used for cylindrical parts are centerless grinding ...
A mathematical model for the parallel winding of circumferential and helical ribs in a cylindrical grid structure is proposed, and the relationship between the number and size of ribs and the thickness of the fibers is established to guide the winding process. A desktop winding system is designed to fabricate the cylindrical grid structure.
The differences between the processes really come down to the shape you are trying to make. Surface grinding cuts a flat, cylindrical grinding cuts a round. You can use the same media on both processes. One other note – you typically mount a cylindrical part between centres or in a collet. For surface grinding you need a magnetic chuck or you ...
