Plunge or Infeed Grinding . Plunge grinding is a simple form of grinding process comparable to conventional cylindrical plunge grinding. During the plunge operation the workpiece does not make any axial movement, and the regulating wheel is dressed parallel to the grinding wheel. The workpiece is placed into the grinding gap from above.

Based on this work, the author has successfully developed the GrindSim software to set-up and optimise cylindrical grinding processes. Two possible criteria can be used to design a centerless grinding cycle: 1) Minimise the process cycle time or 2) Adjust the cycle to a previously established process time, minimising wheel wear.

Gear grinding process is the method of finish grinding gear teeth and is a significant step when building high precision gearing.Gears with precision ground teeth work more softly and consume more evenly than gears with cut teeth. Gear grinding process is often done as a step in the gear manufacturing method, and we also give a gear grind only service.

Note: Low Stress grinding is a process where the grinding wheel is a friable abrasive such as a white aluminum oxide and very soft (normally less than a "G" hardness). Many times the porosity is extremely open (on a scale of greater than 13 using a common structure where 7 is a standard structure or porosity and 10 or greater is an open

The centerless process is commonly used for high volume production, and it's also easily used for low volume production because the machine setups are fairly simple. In thrufeed centerless OD grinding the workpiece passes between two wheels, a grinding wheel and a regulating wheel (as illustrated in the diagram, right).

The purpose of this article is to demonstrate the calculation of wheel life in creep-feed grinding. Calculating wheel life is essential for forecasting wheel usage and the abrasive costs associated with a grinding process. In order to calculate the wheel life, it is essential to know which dressing methodology is being used.
