Grinding flat or plane surfaces is known as surfaces grinding Two general types of machines have been developed for this purpose; those of the planer type with a reciprocating table and those having a rotating worktable Each machine has the possible variation of a horizontal or vertical positioned grinding wheel spindle Thegrinding machines perform the dressing task automatically The application of coolants to the grinding process is important Coolants reduce grinding machine power requirements, maintain work quality, stabilize part dimensions, and insure longer wheel life Coolants are either emulsions, synthetic lubricants or special grinding oilsBasics of Grinding Manufacturing

Honing (metalworking) Wikipedia
Honing machines are much more compliant than grinders The purpose of grinding is to achieve a tight size tolerance To do this, the grinding wheel must be moved to an exact position relative to the workpiece Therefore, a grinding machine must be very stiffan important role in size variations of a product By eliminating the green color labelled causes from the Cause and Effect diagram, we get both significant and insignificant causes, for the variations to occur in a grinding machine Figure 1: Cause and Effect Diagram forthe Size Variation by Considering the 4M’sQUALITY IMPROVEMENT OF A GRINDING OPERATION

A variation to the process can generate profiles in the part 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, crushgrinding the profile on the workpieceGrinding on a Swiss offers several advantages over milling Grinding is a continuous cutting process, which can provide a better finish than milling’s interrupted cutting process, which induces vibration into the part being machined Grinding processes operate at a much higher sfpm than millingGrinding on a Swiss : Production Machining
Grinding machine Wikipedia
A grinding machine, often shortened to grinder, is one of power tools or machine tools used for grinding, it is a type of machining using an abrasive wheel as the cutting toolEach 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 (eg, low surface roughness) and highsimple straight profiles on grinding wheels as well as complex forms using the machines CNC capabilities Stationary dressing tools can be used for a wide variety of applications from internal grinding with very small grinding wheels to much larger wheels as would be used in automotive cam and crankshaft grindingDRESSING OF GRINDING WHEELS DR KAISER
