About AIAbrasives
A free AI-powered grinding wheel speed calculator built for machinists, grinding operators, and manufacturing engineers. We help you find the right RPM, SFM, and peripheral speed for every grinding operation.
Our Mission
Grinding wheel speed is one of the most critical — and most misunderstood — parameters in machining. Too fast and you risk thermal damage, wheel breakage, or poor surface finish. Too slow and you lose productivity and cutting action.
Most machinists rely on rule-of-thumb charts or outdated formulas. Our mission is to make accurate grinding speed calculations accessible to everyone — free, instant, and backed by AI recommendations tuned to your specific material and surface finish requirements.
What We Offer
Free Speed Calculator
Calculate RPM, SFM, or peripheral speed from any two inputs. Supports both Imperial (inches/SFM) and Metric (mm/MPS) units with instant conversion.
AI Material Recommendations
Select your workpiece material — Steel, Stainless, Aluminum, Carbide, Ceramic, Cast Iron, or Titanium — and get AI-optimized speed ranges for your operation.
Surface Finish Guidance
Set your target Ra surface finish and get feed rate recommendations alongside your speed calculation. Match your grinding parameters to your quality goals.
