we are doing stellite 6 HVOF coating on Valve Plug for plug valves.
we are planning to grind the coated surface on cylindrical grinding machine. Can any one suggest which is the best wheel to use for grinding stellite 6. We are looking at huge volume, grinding time is critical.
Looking forward for help .

Hi Ravi,
Diamond wheels work very well for your application and please note that use of diamond wheels always depend on what surface finish you are expecting.
if you use D126 type grinding wheel, surface finish will be in the range 0.75 to 1 micorns Ra and you can use D30 grinding wheel to get better suface finish in the range of less than 0.1 microns Ra.
Regarding grinding time, you can reduce by using good grinding fixtures, good dressing set-up.
