TRW FUJI Valve CBN Grinding Test

If a valve with the wrong diameter is loaded, wheels not treated by MicroEdge® will strip out instantly. In a TRW Automotive test, wheels that were MicroEdge metal treated performed through eight wrong-sized valves. Despite the error, treated wheels still showed a 400% increase in life and prevented more than 16 hours of downtime.

Longer lifespans for wheels resulted in significant cost savings for TRW. Typically it takes TRW more than two hours to change and set up a grinding wheel and the cost of each wheel is $1,200.
