A grinding dresser or wheel dresser is a tool to dress (slightly trim) the surface of a grinding wheel.Grinding dressers are used to return a wheel to its original round shape (to true it up), to expose fresh grains for renewed cutting action (including cleaning away clogged areas), or to make a different profile (cross-sectional shape) on the wheel's edge.
Grinding is prohibited on the side of a typical (disk-shaped) bench grinder wheel, which is designed for grinding on the periphery only. Grinding on the side of a wheel can cause the wheel to explode. Some tool and cutter grinders have cup-shaped wheels designed to do grinding on the side.

Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface.
A loaded grinding wheel is a result of chips clogging the grains on the grinding wheel due to the grinding of soft materials, improper grinding wheel selection processing parameters. In addition to sharpening a grinding wheel dressing can also be used to true a grinding wheel that is out of round or to shape the profile of a grinding wheel to ...
A schematic of ELID grinding. Electrolytic in-process dressing (ELID) grinding: in this ultra-precision grinding technology, the grinding wheel is dressed electrochemically and in-process to maintain the accuracy of the grinding. An ELID cell consists of a metal-bonded grinding wheel, a cathode electrode, a pulsed DC power supply, and electrolyte.
The expanded maternity unit is designed to handle 3,500 deliveries a year. The expansion of the heart center included two operating rooms and many cardiology upgrades allowing it to function as a fully functioning emergency cardiac treatment center. Following this, in July 2003, an $18 million project to expand the emergency room was completed. [9]
A schematic diagram of the centerless grinding process. Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their ...
