i need you to contact the people who made these wheels and ask them if it is diamond and also the concentration and mesh size.
these aren’t grinding the carbide very well at all.
just so you know these wheels are being used for grinding carbide on circular saw blades. they get used on ollmer ch21 (automatic sharpening machine)
i he put one of your wheels on and they do not grind very well. they seem to me like they are cbn. also they aren’t as dark in colour as my usual diamond wheels. they are more brown and my normal wheels are more black
i am disappointed that i waited for so long and the wheels you he sent are not up to standard . i cant see how they are diamond because they wont grind the carbide very well.
我就是不能理解??carbide? ?究竟是 硬质合金??还是碳化物? ? ?????????有这样的砂轮吗??????各位大神帮帮忙 ,下女子感激不尽哈??。。。。。。。急求[收起]
