What is a Diamond Dresser?
A diamond dresser has single or multiple diamonds mounted on a tip or a shank by a sintering process. Diamond dressers are widely used for truing and dressing of abrasive grinding wheels. A popular aspect in the diamond tool manufacturing industry. Here are some tips on using single point diamond dressers.
Inclining for Longer Life
Extend the overall life of a single point diamond dresser by inclining the tool at a 10 to 15 degree angle to the wheel radius. Point the tool in the rotation direction of the grinding wheel in order to properly maintain a consistently sharp point.
When dressing with diamond single points or arbitrary stone tools, then the infeed has to be .001 since the diamond dressing tool will inevitably pulverize the vitrified bond. When higher than the .001, there may be cracking into the wheel that eventually forces the bond to degenerate. On top of that, gullets may develop that produce loading by catching chips and overheating the wheel. The main consequences of excessive infeed are chatter, bounce, bad finish and burn.
Utilize Sharply Tipped Octahedrons
Sharply tipped, crystal octahedrons should be utilized for straight dressings. Some work really well and points associated with crystal octahedrons stay sharp if you turn the tool six to twelve indexes every revolution.
When using single point diamond dressers, be sure to use enough coolant in order to moderate dressing temperatures. Otherwise, there may be overheating, which in turn can chemically transform diamond into graphite. And if faced against large temperature gradients, diamonds can also crack as a result.
Perform Dressing Regularly
The main objective of dressing is to generate and expose novel, superficial cutting edges on the wheel. And single point diamond dressers achieve this objective by shattering existing gravelly grains and then aiding the emergence of the abrasive particles you want shown. Dressing increases in-feed and must be performed regularly in order to maintain optimal grain protrusion and grain edge sharpness.
Begin Dressing at Center of Wheel
When using a single point diamond dresser, it is important to note that you must always begin dressing at the center of the wheel since it has the biggest diameter. Starting a dressing procedure at a wheel’s side will likely end up with the diamond shattering or even destroying it.
Prevention of Wheel Taper
In order to prevent wheel taper, you can place the single point diamond dress as close as possible to the grinding area.
Impact of Longitudinal Feeds
The grinding wheel grain sizes are contingent on longitudinal feeds, which significantly influence the structure of the surface of a grinding wheel. For finer surfaces, you can reduce the feed rates.
Rotation of Dresser
Rotate the dresser 20 to 40 degrees in the shank if a flat appears on the diamond. This is so the dresser maintains an optimally conical point.
Do Not Let Diamond Erode
It is important to avoid letting the diamond erode until the shank is visible. If the diamond erodes prematurely, it can allow the stone to dislodge or fall out.
