Diamond Cutting Disc for Quartz

Product Introduction

This quartz dedicated diamond cutting disc is a high-precision resin bonded outer rim cutting wheel. The outer ring is the diamond working abrasive layer, while the core substrate adopts high-strength rigid metal base. The metal substrate and diamond rim are integrally bonded, featuring high rigidity and low deformation during cutting, suitable for heavy-load deep cutting of hard & brittle quartz materials.

Quartz glass has high hardness, extreme brittleness and ultra-low thermal expansion coefficient. Ordinary cutting tools easily cause chipping, cracks and thermal burn on workpieces. Our cutting disc uses premium diamond grit together with high-performance resin bond, presenting excellent self-sharpening performance. It delivers clean cuts with minimal chipping and no cracks. Narrow kerf design helps save costly quartz raw materials and improve material utilization.

Technical Specifications

Key Features

• High rigidity & low deformation: High-rigidity metal substrate reduces wobble during cutting, ensures good perpendicularity of cut surface, ideal for deep cutting.
• Superior cutting quality: Resin bond provides moderate elasticity. Cuts on quartz workpieces are smooth, free of chipping, cracks and burn marks, reducing subsequent polishing work.
• Sharp cutting & good self-sharpening: Excellent self-sharpening property allows higher feed rate. No frequent dressing or wheel replacement, greatly boosting production efficiency.
• Long service life & high wear resistance: Strong grit retention from resin bond, stable cutting edge and extended lifespan.
• Narrow kerf for material saving: Ultra-thin body minimizes kerf loss, ideal for high-value quartz materials.
• Flexible application: Single wheel operation or multi-wheel gang cutting supported. Grit size & concentration adjustable to balance cutting speed and surface finish.
• High precision: Strict dimensional and geometric tolerance control for precision cutoff and grooving.
• Good flexibility: Better flexibility compared with metal-bonded cutting wheels, suitable for delicate and partial curved cutting tasks.

Additional Notes

Custom service available. We can adjust diamond grit, concentration and resin bond formula according to your quartz cutting conditions. Stock items and custom production are both available for trial small orders and mass production.

• • Inspect cutting disc before mounting. Do NOT use cracked, chipped or damaged wheels.
  • The rotation arrow marked on the disc must match the spindle rotation direction; otherwise cutting performance will drop.
  • Use only for cutoff and grooving. Do not use for grinding or other unauthorized operations.
  • Stop the machine immediately if abnormal noise or vibration occurs.
  • Dress the wheel once it gets dull. Continued use of blunt wheels leads to overheating and risk of wheel breakage.
  • Keep hands away from rotating disc and wear proper protective gear.
