CV Joint Grinding
Constant-velocity joints transmit torque between two angularly offset shafts and place high demands on dimensional accuracy, surface quality, and reproducibility.
Process
When grinding the cage windows and the ball raceways, controlled material removal with minimal thermal impact is essential.
Ceramic-bonded CBN grinding tools enable stable processes with high form accuracy – particularly in series and high-volume applications in the automotive industry.
What the process gains
High material removal rate
Shorter cycle times and increased production capacity
Low heat generation
Reduced risk of grinding burn, stable microstructure
Long dressing intervals
Lower tool wear and reduced downtime
Microporous bond structure
Improved coolant supply at the point of engagement
