Precision grinding ensures surface is uniform, accurately shaped, and smooth. This reduces friction, minimises noise, and extends gear components life. CUMI’s precision grinding wheels are engineered for tight tolerances and form stability, making them ideal for producing high-performance gears.

• Selecting a wheel with balanced density and optimised grain structure minimises chatter and vibration. CUMI wheels are dynamically balanced and customised for your machine parameters, ensuring quieter, more stable operations.

• If production stops due to wheel damage or performance issues, CUMI’s technical team addresses and resolves the problem within 48–62 hours, ensuring minimal downtime.

• Yes. Whether you need wheels for spur, helical, bevel, or special gear forms, CUMI designs customised solutions with the right bond, grit size, and wheel geometry to match your exact application.

• Switching to a fine-grit wheel with a stable bond system can achieve a smoother finish while maintaining accuracy. CUMI’s cork-bond wheels are specifically designed for achieving a refined, low-surface finish.

When selecting a grinding wheel for precision work, focus on these key factors:

• Material Compatibility – Match the abrasive type to the gear material (e.g., microcrystalline alumina for hardened steel, silicon carbide for cast iron).
• Wheel Profile & Shape – Ensure the wheel’s geometry aligns perfectly with the gear component for uniform contact.
• Grit Size – Use coarser grits for rapid stock removal; finer grits for smoother operational surfaces.
• Operating Speed & Feed Rate – Choose a wheel that can handle your machine’s parameters without causing thermal damage or distortion.
  
• Process Goals – Decide whether the focus is high removal rates, fine surface finish, or extended wheel life.
