CUMl’s IR Track grinding wheels utilize a special fusible glassy bond combined with a sharp abrasive grain, which ensures effective form holding and high material removal rates in applications involving high contact areas. An advanced manufacturing process ensures that the wheel’s hardness is consistent through the wheel life and the highest levels of safety are maintained. With all the latest advancements in the field of automobiles and machine manufacturers, the functions of bearings are now more crucial than ever before, thereby placing greater demands on the quality of bearings. Track grinding wheels must maintain their shape to ensure the profile accuracy of the inner ring’s track. This ensures that the wheels are dressed less often, leading to significant improvements in productivity and consistency in the process.

Product Description

IR Track Grinding Wheels for Bearing Industry

Inner Ring (IR) track grinding is one of the most critical finishing steps in bearing manufacturing, affecting load distribution, rotational accuracy, and bearing life. CUMI IR Track Grinding Wheels are engineered using a special fusible glassy bond and sharp precision abrasive grains to maintain form consistency, reduce dressing frequency, and deliver high stock removal even under continuous high-contact grinding.

Feature → Advantage → Benefit

  1. Glassy vitrified bond → excellent form holding → maintains inner-track accuracy and reduces rejection
  2. Sharp precision abrasive grains → aggressive cutting action → faster stock removal & shorter production cycles
  3. Consistent hardness throughout wheel life → same performance from start to end → predictable machining outcome
  4. Designed for high-contact grinding area → optimized heat control → prevents burns & micro-cracks on bearing raceways
  5. Reduced dressing requirement → less downtime → maximizes productivity and throughput in bearing plants

Industry: Bearing industry – IR (inner ring) raceway & track grinding in high-precision bearings

FAQs
