automated system |
Any system that does not require human intervention. An automated dresser would be part of the machine setup and would require little in-process attention. |
automatic balancer |
A device that uses one of several methods, including gasses and fluids, to detect vibration. |
balancing |
The process of making a wheel round or concentric. Balancing may be accomplished through several methods, including truing with a diamond dresser. |
balancing stand |
A frame-like device on which a grinding wheel is placed to check for balance. The grinding wheel is first mounted on a mandrel. |
blotter |
A paper ring that helps buffer mounting pressures between the wheel and the flange. |
chatter mark |
An irregular mark left on a workpiece that has been ground with a wheel that is out of true. |
concentric |
Similarity between two circles, both having a common center, such as the center hole on a grinding wheel and its outside edge. |
crush roll |
A hard grinding wheel used under pressure to improve the face of another grinding wheel and usually to add a special shape. |
diamond disc |
A type of grinding wheel with diamonds projecting from its periphery. Used for wheel dressing. |
diamond dresser |
A tool containing one or more diamonds used to remove material from the surface of a grinding wheel. |
dressing |
The removal of swarf, dull grains, and bonding material from a grinding wheel. Dressing sharpens the wheel. |
dynamic balance |
The ability of a grinding wheel to come to rest only when it loses momentum. The wheel is mounted on a mandrel and rolled along a balancing stand. |
flange |
A flat or raised metal disk that helps deflect mounting stresses from the wheel's hole. |
glazing |
The unwanted formation of a smooth surface on a grinding wheel. Glazing occurs when the heat from grinding reacts with a loaded wheel. |
lock nut |
A type of nut that screws down on top of another nut to hold the first one in place. The lock nut is usually thinner than the nut it is holding. |
magnetic chuck |
The moveable surface on a grinding machine that holds the workpiece or dresser in place. |
mandrel |
The spindle or post on which a wheel is mounted. |
mounting |
The attaching of the wheel to the grinding machine. Often involves placing the wheel on a spindle. |
profile |
A specialized edge that is added to the face of a wheel to help it conform to a particular grinding operation or part shape. |
ring test |
A manual test used to detect damage in bonded grinding wheels. Operators suspend a wheel loosely and tap it with a tool. Wheels that emit a ringing sound are likely undamaged. |
rotary dresser |
A dressing tool that turns as it dresses, such as a wheel with diamond abrasive. |
self-dressing |
A method of wheel dressing that uses increased pressure or feed to force material from the face of a grinding wheel while it is in use. |
shaping |
The changing of the profile of a grinding wheel. |
single-point diamond |
In grinding, it is one industrial-grade diamond embedded in the end of a wheel-dressing tool. |
sleeve |
A type of flange that fits together with two differently shaped parts and a lock nut. |
static balance |
The ability of a grinding wheel to remain at rest in any position when placed on a balancing stand. |
stationary dresser |
A dressing tool that has a point or points that are fixed. A single-point diamond is the best example of a stationary dresser. |
swarf |
The gritty combination of chips, abrasive grains, and worn bonding material that is produced during grinding. |
truing |
The dressing of a wheel in order to return the wheel to its original shape. Truing is also a method of wheel balancing. |
wheel balance |
A wheel that has equal weight and shape throughout, making it completely concentric. A balanced wheel does not vibrate. |
