A grinding machine, often shortened to grinder, is any of various power tools or machine tools used for grinding, which is a type of machining using an abrasive wheel as the cutting tool. Each grain of abrasive on the wheel's surface cuts a small chip from the workpiece via shear deformation.
Grinding is used to finish workpieces that must show high surface quality (e.g., low surface roughness) and high accuracy of shape and dimension. As the accuracy in dimensions in grinding is of the order of 0.000025 mm, in most applications it tends to be a finishing operation and removes comparatively little metal, about 0.25 to 0.50 mm depth. However, there are some roughing applications in which grinding removes high volumes of metal quite rapidly. Thus, grinding is a diverse field.
Overview
The grinding machine consists of a bed with a fixture to guide and hold the work piece, and a power-driven grinding wheel spinning at the required speed. The speed is determined by the wheel’s diameter and manufacturer’s rating. The grinding head can travel across a fixed work piece, or the work piece can be moved while the grind head stays in a fixed position.
Fine control of the grinding head or table position is possible using a vernier calibrated hand wheel, or using the features of numerical controls.
Grinding machines remove material from the work piece by abrasion, which can generate substantial amounts of heat. To cool the work piece so that it does not overheat and go outside its tolerance, grinding machines incorporate a coolant. The coolant also benefits the machinist as the heat generated may cause burns. In high-precision grinding machines (most cylindrical and surface grinders), the final grinding stages are usually set up so that they remove about 200 nm (less than 1/10000 in) per pass - this generates so little heat that even with no coolant, the temperature rise is negligible

Centerless Grinders
For fast stock removal, lower machine tolerances and size as low as 0.0001″ or better, centerless grinding is the answer. Fortunately, centerless grinding has grown in popularity in the sphere of grinding technology. With centerless grinders, as the name implies, the work is not supported between centers. Instead, it’s held on a blade between the grinding wheel and the regulating wheel, which acts as a brake to set the RPM.
Basically, centerless grinding can be carried out in two different methods:
1) Through-feed
2) In-feed (Plunge cut grinding)
The through-feed method is applicable only when straight cylindrical parts are used. If there’s a head in the work, or the work is of stepped or taper form, the in-feed method would be the best choice. The end-feed method is used for headed components that are too long to be ground by the in-feed method. Generally, the end-feed method is applied when the length of the workpiece is greater than the width of the grinding wheel.
Centerless grinders have many more advantages when compared to center type grinders:
The rate of production is higher in centerless grinding.
The workpiece is provided with better stability
The job is supported along the whole length which prevents the occurrence of deflection. Hence, this process is suitable for long workpieces.

Less stock is needed due to the elimination of centering.
Production costs are lower.
