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!
