F Type Grinding Wheels – Bearing Industry

Good

F type grinding wheels, or fastening-type wheels, are resinoid wheels that are fastened to the back plates using bolts. The face of the wheel is used to grind components and gener­ate flat and parallel surfaces. Used in various industries like bearings, auto, etc. The applications usually demand high stock removal along with tight size tolerances and fine surface finishes. Since the area of grinding is very large, heat generation is high; provisions are made in the chemical and physical design of the wheel to ensure that there is enough scope for heat dissipation by effective utilization of coolants. CUMI wheels are proven to perform at high feed rates and material removal applica­tions while meeting stringent quality requirements in terms of size tolerances, heat generation, and surface finishes, thanks to the special technology of grain-bond combina­tion, which ensures free cutting. Physical features like coolant slots, through holes, and honeycomb structure aid in taking the performance of the wheels to the next level.

Product Description

About F type grinding wheels

Precision grinding in the bearing industry requires flat, parallel surfaces with micro-level tolerances to ensure smooth rotation and extended bearing life. CUMI F-Type Grinding Wheels are engineered to meet these demands — delivering high stock removal, burn-free cutting, and uniform finish through their special resinoid fastening design and coolant-friendly wheel architecture.

Feature → Advantage → Benefit

  • Resinoid fastening-type wheel (bolt mounted) → stable and rigid contact → enables heavy-feed grinding without vibration
  • Special grain-bond formulation → free-cutting action → reduces heat, improves stock removal rate & protects bearing raceway surface
  • Coolant slots, through-holes & honeycomb structure → maximum coolant access → prevents burns & micro-cracks during long grinding cycles
  • Large face-contact design → flat & parallel surface grinding → ensures tight tolerances essential for tapered roller & ball bearings
  • Ability to run at high feed rates → faster throughput → reduces cycle time and cost per bearing component

Industry: Bearing Manufacturing (Tapered roller bearings, deep-groove ball bearings, roller bearings)

FAQs
01.
Which industry is this F type wheel mainly designed for This model is primarily used in the Bearing Industry for roller and raceway surface grinding.
02.
What makes F-Type wheels suitable for bearings? They offer tight tolerance flat grinding, essential for smooth bearing rotation and life.
03.
How do coolant slots improve grinding on bearings? They enhance coolant flow → cooler grinding → prevents burn marks and surface micro-damage.
04.
Can the F type wheel be used on automotive parts? Yes, but this variant is specifically optimized for continuous-duty bearing grinding.
05.
Do these F type wheels support high feed grinding Yes — CUMI F-Type wheels are engineered for high feed rate stock removal.
