Black-Sand Resin Bonded Wheel

Coarse grinding, heavy-duty material removal

Coarse-grit resin bonded wheel with silicon carbide abrasive for aggressive material removal. The fastest-cutting resin wheel — designed for heavy-duty applications where speed matters more than surface finish.

Advantages

Why Black-Sand

Maximum removal rate. Silicon carbide aggression for heavy-duty applications and coated glass.

Silicon Carbide Abrasive

SiC crystals are sharper and harder than aluminum oxide — they maintain cutting action on hard-coated glass where aluminum oxide loads and glazes.

Fastest Resin Cutting Speed

2–3× the material removal rate of finer resin wheels. The fastest way to remove stock in the resin wheel family.

High-Density Bond

Tough resin matrix handles the increased thermal and mechanical loads of aggressive grinding without premature wear or chunking.

Coated Glass Specialist

Silicon carbide's sharp crystals cut through Low-E and solar control coatings without loading — the best resin choice for coated architectural glass.

Fastest Resin Cutting Speed

2–3× the material removal rate of finer resin wheels. The fastest way to remove stock in the resin wheel family.

Applications

Where It Excels

The fastest-cutting resin wheel for heavy-duty removal and coated glass processing.

Heavy-Duty Material Removal

Thick Glass & Chamfering

Black-sand resin wheels remove material at 2–3× the rate of finer resin wheels. For operations processing thick glass (12mm+) or requiring significant stock removal — chamfering edges, roughing bevel profiles, or processing structural panels — black-sand delivers the throughput that finer wheels cannot match.

Maintenance

Keep Them Cutting

Five essential practices to maximize wheel life and maintain consistent edge quality under aggressive grinding loads.

Black-sand wheels generate the most heat of any resin wheel. Increase coolant flow 20–30% above standard resin wheel settings to prevent thermal damage.

Under excessive load, the coarse SiC can cause small chunks of resin to break away. If chunking appears, reduce feed speed or grinding pressure.

Black-sand leaves a rough surface. Always follow with green or red resin for applications requiring polished edges. Skip the follow-up only for rough-edged products.

Coated glass accelerates wheel wear by 30–50%. Track meters processed separately for coated vs uncoated glass to predict replacement timing accurately.

Check the wheel for cracks or bond separation before each shift. The aggressive loads of coarse grinding can propagate small defects into catastrophic failure.

FAQ

Common Questions

Everything you need to know about black-sand resin bonded wheels.

Use black-sand when you need to remove more than 0.5mm of material per pass, when processing hard-coated glass (Low-E, solar control), or when chamfering thick glass edges. For general-purpose fine grinding under 0.5mm removal, green resin is more efficient.

No. Black-sand resin wheels are fine grinding tools, not primary grinding tools. They cannot shape glass or remove the material volumes that diamond wheels handle. Use diamond wheels for primary shaping, then black-sand for rapid stock removal in the fine grinding stage.

Reduce feed speed by 20–30% when processing coated glass. Ensure coolant is flowing generously — heat is the primary cause of coating delamination. If coating damage persists, switch to green resin for a gentler approach.

On uncoated float glass: 800–1,200 linear meters. On coated glass (Low-E, solar control): 500–800 linear meters. The harder coating surface and increased friction accelerate SiC crystal consumption.
