grinding wheel for stellite 6 hvof coating

[raviswanadha]

Hi,
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 .
Best Regards

Hello there - We successfully use silicon carbide grinding wheels for this application. It would help you production if you are using a grinder with auto sizing and auto dress/compensation.

Good luck

Thank you for your suggestion. could you further let me know what grit size of the wheel to use. 60-80 grit size would do ?

In our company, We have made Stellite 6 coating on 316L steel. We use Silicon Carbide and also Diamond (100 C) wheels. The SiC can use a little bit slower cutting speed but You can choose to be less expensive.

The grit size is dependent on your finish requirement. If this is not a critical factor and you are using a rigid setup, I see no problems in using the 60 grit with a higher infeed.

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.

Hi

W are grinding stellite 6 with CBN it works very well,

In lower volume production, and repair we often used AlOx Belts and got great speeds, and excellent finishes.
