The double-sided ceramic CBN grinding wheel is specifically designed for high-efficiency, high-precision grinding of automotive components such as gears, bearings, and transmission parts.With vitrified bond technology, it provides superior form retention, excellent thermal stability, and long dressing intervals.The dual-face design allows simultaneous grinding of both sides, improving flatness, parallelism, and production throughput.
High Efficiency: Simultaneous double-sided grinding ensures fast material removal and consistent accuracy.
Superior Precision: Excellent surface finish and tight dimensional control for automotive-grade requirements.
Long Service Life: Vitrified bond provides strong grit holding power and outstanding wear resistance.
Stable Performance: Performs reliably under heavy-load, high-speed conditions.
Low Maintenance: Reduced dressing frequency and minimal wheel deformation.

A leading automotive parts manufacturer used the D1000×T58×H410×t6 mm vitrified CBN double-sided grinding wheel on Stahli and Lapmaster double-disc grinders to process martensitic stainless steel components after heat treatment (45–50 HRC).
Process Setup:
Rough Grinding: 150# CBN grit, stock removal 0.50 mm
Fine Grinding: 325/400# CBN grit, stock removal 0.05 mm
Surface Finish Achieved: N4 (Ra＜0.4 μm)
Dressing: WA dressing wheel used periodically
Achieved high parallelism and uniform surface quality across large batches
Stable grinding performance with minimal wheel wear
Reduced dressing frequency by 40% compared to resin-bonded wheels
Improved productivity and reduced part rejection rate
