periphery (circumference). The dresser comes in contact with the grinding wheel and rotates. In this process, the projections dress the grinding wheel. Generally, a number of such discs are used together at a time mounted on a shaft. This type is used for grinding wheels with coarse grain size. Sometimes they are also referred as Star-Disc

Process equipment: M1430A Process content: two top tips, (the other end is blocked with a cone) (1) coarse grinding of φ40 outer circle, leaving 0.1 to 0.15 remaining (2) coarse grinding φ30js outer circle to φ30t+0.1+0.08 (two places) step grinding
The grinding machine provides high accuracy and fine surface finish with minimum tolerances. The machining process is done by the abrasive action of the grinding wheel; the abrasives are embedded over the periphery of the rotating wheel. In Grinding machine grinding wheel is work as a cutting tool and responsible for all machining processes.
Our machining capabilities came along as a natural progression of our precision grinding process. We have been producing shafting for the oil & gas industry for over eight years. In an effort of continual improvement and seeking new industries to apply the talents of our machining team, we added small parts machining capabilities.
Since surface texture is dependent on manufacturing process, shaft drawings should designate "fine grinding" or "diamond grinding" in addition to the usual surface finish symbol (Figure 2). Avoid vendors who achieve the designated surface finish by filling in the porosity of the tungsten carbide coating with a plastic coating.

In centerless through feed grinding, which is a typical serial grinding process, pistons for the automotive industry, shafts, rods and also elements for the rolling bearing industry are produced. Internal cylindrical grinding: Internal cylindrical grinding is one of the most common and also most difficult grinding operations.
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.
Centerless grinding is the process of removing material from the outer diameter of a workpiece using a grinding wheel. The workpiece is located on its outer diameter and supported by a working blade located between the adjusting wheel and the grinding wheel. The adjustment wheel drives the machined parts, and the grinding wheel removes material.

Factors affecting this will include the material composition, how the shaft is forged, heat treatment, grinding techniques, induced magnetism, stress, and material handling. If excessive runout is not eliminated during the manufacturing process, the motor would have to be disassembled and the shaft reworked.
During the remanufacturing process the machinist is mostly concerned with grinding the rod and main journals. Upon initial inspection of the crankshaft, with the use of the micrometer, the machinist will determine what bearings need grinding. Indicators that a journal needs grinding include if the surface has wear and make it rough to the touch.
Your objective of doing cylindrical grinding is-. To get a good surface finish. Geometrical accuracy like concentricity between two or more diameters on a shaft or between the bore and outside diameter of a cylindrical work-piece. Most importantly, to machine the hardened work-piece for which grinding is the only machining process.
