Launch the Grinding Wheel Specification Generator
No installation or build tools are required. The generator runs directly in a modern web browser.
This tool helps grinding engineers and machinists quickly verify wheel parameters, surface speeds, and recommended grinding conditions for diamond and CBN (Cubic Boron Nitride) superabrasive wheels.
It is not a replacement for manufacturer data sheets or process engineering judgment — it provides first-order estimates to guide setup and catch common mistakes.
- Surface Speed Calculation — converts wheel diameter and RPM to m/s and ft/min
- Recommended Parameters — depth of cut, table speed, RPM limits based on bond type and workpiece hardness
- Basic Grinding Outputs — MRR (Material Removal Rate), grinding power, G-ratio, chip thickness
- Wheel Volume & Weight — estimated from bore, OD, width, and bond density
- Safety Warnings — alerts for overspeed, wrong abrasive-material pairing, and dry grinding risks
Surface Speed (m/s) = π × D(m) × RPM / 60
MRR (cm³/min) = Depth of Cut(mm) × Width(mm) × Table Speed(m/min) / 1000
Grinding Power (kW) = MRR × Specific Energy / (60 × 1000)

| Bond | Max Surface Speed | Source / Reference |
|---|---|---|
| Resin Bond | 35 m/s | Resin bond wheels typically rated 25–50 m/s; 35 m/s is a common conservative limit. — Norton Grinding Wheel Catalogue; Saint-Gobain Abrasives Technical Reference |
| Vitrified Bond | 60 m/s | Vitrified bond wheels rated up to 60–80 m/s depending on grade and reinforcement. — Winterthur Technology Group Technical Manual; Kellenberger grinding specifications |
| Metal Bond | 25 m/s | Metal bond wheels limited by bond strength and heat generation; 20–30 m/s typical. — EHWA Diamond Technical Guide; Asahi Diamond Industrial Co. |
| Electroplated | 40 m/s | Single-layer electroplated wheels limited by nickel bond adhesion; 30–50 m/s typical. — Dr. Kaiser Diamantwerkzeuge Catalogue; Engis Corp. Technical Notes |

| Stainless Steel | CBN | Same iron-reactivity issue as carbon steel. — Malkin & Conring; Sandvik Coromant Grinding Handbook |
| Cast Iron | Diamond | Graphite flakes make cast iron non-reactive to diamond. — Malkin & Conring; Norton Abrasives Application Guide |
| Hardened Steel (>45 HRC) | CBN | CBN retains hardness at high temperatures; preferred for hardened ferrous. — Malkin & Conring; Schmitt Superabrasives Technical Bulletin |
| Tungsten Carbide | Diamond | Diamond is the standard for cemented carbide grinding. — Sandvik Coromant; Kennametal Grinding Guidelines |
| Technical Ceramic | Diamond | Ceramics are extremely hard; only diamond has sufficient hardness. — Malkin & Conring; 3M Superabrasives Guide |
| Glass / Quartz | Diamond | Standard industrial practice. — Norton / Saint-Gobain Abrasives; Schott AG Processing Guidelines |
| Silicon / Semiconductor | Diamond | Silicon wafer dicing and grinding use diamond exclusively. — Disco Corporation Technical Manual; Applied Materials Grinding Notes |
| Titanium / Superalloy | CBN | Titanium is chemically reactive with diamond at high temps; CBN preferred. — Malkin & Conring; GE Superabrasives Application Notes |
| PTFE / Composites | Either | Low hardness; both abrasive types work. Coarse grit preferred. — Composites Manufacturing Association Guidelines; Engis Technical Notes |
| Material | Specific Energy (J/mm³) | Source / Reference |
|---|---|---|
| Steel (Carbon / Alloy) | 60 | Typical range 40–80 J/mm³ for steel grinding. — Malkin & Conring, Table 3.2; Rowe, "Principles of Modern Grinding Technology", Springer |
| Stainless Steel | 70 | Higher than carbon steel due to work hardening tendency. — Malkin & Conring; Sandvik Grinding Handbook |
| Cast Iron | 30 | Lower due to graphite flake lubrication and brittleness. — Malkin & Conring; Rowe |
| Hardened Steel | 80 | Harder materials require more energy per unit volume removed. — Malkin & Conring; Rowe |
| Tungsten Carbide | 100 | Very hard material; high specific energy. — Malkin & Conring; Schmitt Superabrasives |
| Technical Ceramic | 120 | Extremely high specific energy due to hardness and brittleness. — Malkin & Conring; Rowe |
| Glass | 90 | Brittle fracture dominates; moderate specific energy. — Malkin & Conring; Moore "Precision Grinding" |
| Silicon | 110 | Brittle semiconductor; high energy to remove material. — Disco Corporation; Bridging published wafer grinding data |
