HACO-FLEX: As easy as an erasor
Regeneration of the abrasive layer: puts the bite back into diamond and CBN grinding bonds
With the flexible HACO-FLEX you obtain an optimal grain protrusion in your resin and metal bonded wheels.
- Increased grinding performance
- Cooler grinding with less pressure
- Shorter grinding times
- Higher tool life
Problem and solution
Problem
The bond and the abrasive grains are at the same level. The grinding tool only presses, but has no bite.
Solution
The flexible HACO-FLEX regenerator is pressed either by hand or by machine, without a coolant, into the abrasive layer (wheel turning at reduced speeds). It penetrates deeply and, like an eraser, it exposes the chip spaces until the abrasive grains protrude by about 1/3 above the bond.
Result
The abrasive grains are now protruding from the bond. The grinding tool has got back its proper bite.
Variations
For regenerating grinding tools with standard grit sizes D/BN 46 - 251:
RGIW
Blue rubber stick
Stiffer, but less agressive/abrasive
RSCE
Grey rubber disc
More flexible and more agressive/abrasive
RGIH
Grey rubber stick
More flexible and more agressive/abrasive
For very fine grit sizes D/BN 13 - 39:
SFEIN
Soft ceramic stick
Application
- Reduced cutting speeds, 26 m/s at most.
- Hold the HACO-FLEX firmly in place when used manually.
- Hold the HACO-FLEX into the bond for a few seconds. If used for too long, it can alter the profile of the wheel.
- Use HACO-FLEX dry. It should not get wet with oil or emulsion.
- At the end, the roughness of the bond surface should be clearly felt when you drag your fingernail across the surface (exception: fine grit sizes). The grinding tool has a strong bite again!
