6" 150mm 4-in-1 Abrasive Wheel Kit Diamond Resin Ceramic Green SiC Wheels Dresser Arbor Bushings for Welding Blade Sharpening

150x20x32mm Abrasive Wheels

Special for Brazed Carbide Turning Tool and Tungsten Carbide Tipped Saw Blade.
Green Silicon Carbide Wheel for the steel blade body/back;
Diamond Wheel for the carbide cutting edge.

Step 1: Grind the Steel Body/Tooth Back (GC wheel)

First, grind the steel shank or tooth back using the Green SiC wheel. Create a relief angle that is 2°~5° larger than the carbide tip (typically 25°~30° for the steel body versus 20° for the carbide). Lightly grind dry or with minimal water cooling, removing approximately 0.5~1.0mm of material.

Step 2: Rough Grinding the Carbide Cutting Edge (Diamond Wheel)

Switch to a resin-bonded diamond wheel. Apply light pressure and feed along the original rake/clearance angle. Limit the depth of cut to ≤0.02~0.05mm per pass. Always perform down-grinding (feed toward the tool root) to minimize chipping.
Remove the worn layer and minor chips. It is essential to use a coolant (water-soluble cutting fluid at 3~5 L/min) to prevent thermal cracks.

Dressing the Wheel

Regularly dress the diamond wheel using a diamond dressing tool (diamond pen). This exposes fresh abrasive grains and prevents the wheel from glazing or loading (clogging)
