With single point dresser with
an idle pass for "better finish"
wheel grains are completely
burnished resulting in
total loss of abrasive action |
|
|
With a "blunt" single point dresser
grains have been pulled out
resulting in cavities and chances of
wheel getting loaded quickly
grinding during operation |
 |
|
With a single point dresser at a lower
dressing rate for "better finish" cavities
filled with loose unbounded abrasive
grains which initially result in a
rubbing action
and later in "wheel loading"
|
 |
|
With blade dresser notable features
1. Proper grain fracture and greater abrasive
action of individual grains
2. No cavity formation- less chances of
wheel loading ¬greater abrasive area
3. No grains pull out ¬greater abrasive area
4. No loose grains "filled up" consistency in surface finish
