1FF1 Diamond Grinding Wheel – Double-Sided Conical Profile | FEPA D91 (80/63 μm)
1FF1 flat diamond wheel with double-sided conical profile for profile grinding of cutting tool features.
Designed for carbide and other hard brittle materials.
Where it is actually used:
Used for grinding chip-breaking flutes and narrow profiles with reduced grinding forces.
Typical applications include:
- Profile grinding with limited machine rigidity
- Chip breaker geometry on end mills and drills
- Operations where lower load on spindle is required
The double-sided conical profile enables stable profile generation with controlled contact.
What it actually does:
Controlled material removal with reduced cutting forces.
Easier cutting action compared to 100% concentration, especially in sensitive setups.
Grain size (D91 ≈ 80/63 μm):
- Moderate to high stock removal
- Typical Ra ~ 0.4–1.0 μm
- Prepares surface for M63 → M40 sequence
More forgiving and less prone to loading.
Concentration 75% means:
- Lower grinding forces
- More open structure → better chip clearance
- Smoother cutting behavior
- Trade-off: shorter tool life vs 100%
In practice:
This is a more forgiving roughing wheel.
Used when machine rigidity is limited or heat generation must be reduced.
Focus is stable process rather than maximum productivity.
Specification:
- Type: 1FF1 (double-sided conical)
- Abrasive: Synthetic diamond (AC4)
- Grit: FEPA D91 ≈ 80/63 μm (ANSI 170/200)
- Concentration: 75%
-
Body: P / A / S / Ap
(Pressed / Aluminum / Steel / Aluplast)
Body options:
- Pressed: lighter weight, vibration damping, better surface finish
- Aluminum: lightweight with good rigidity, general-purpose solution
- Steel: maximum rigidity for heavy-duty grinding
- Aluplast: balanced weight and rigidity
Why this shape:
- Access to narrow grooves
- Controlled profile generation
- No interference in tight areas
Use for:
- Chip breaker flutes
- Tool profile grinding
- Stable rough grinding
Do not use for:
- Heavy stock removal with high pressure
- Final finishing
- Polishing
