Product Description

Precision balls in the bearing industry demand exceptional sphericity and micro-finish quality, as even micron-level deviations can affect noise level, load distribution and bearing lifespan. CUMI Ball Grinding Wheels are designed for continuous-duty, high-speed grinding where form accuracy and long wheel life are critical — helping manufacturers enhance output quality while reducing per-ball production cost.

Feature → Advantage → Benefit

  • Vitrified precision bond → superior form holding → maintains roundness & avoids flat spots
  • Premium abrasive grains → faster material removal → reduced grinding cycle time
  • Customized hardness & structure → matched to ball size & material → lower heat generation, burn-free finish
  • State-of-the-art manufacturing → uniform wheel performance batch-to-batch → better predictability in mass production
  • Designed for high productivity → less dressing requirement → reduced downtime & operating cost

Industry: Bearing Industry – steel ball grinding, pre-finish & finish grinding stages

FAQs
