Product Details

Item name: Electroplated diamond/CBN grinding wheel

Abrasive Grain: Diamond / CBN

Body material: steel

Package: 10pcs/lot

Usage: Diamond grinding wheels are used for hard carbide, optical glass, gem, semi-conductor materials, non-ferrous materials, and non-metallic material grinding, cutting or electrolytic grinding.

CBN grinding wheels are used for grinding ferrous metal, such as refractory alloy, vanadium steel, cobalt steel, molybdenum steel, high speed steel, bearing steel and titanium steel etc. Customized super abrasives are also available for various procedures.

Choose Diamond or CBN grinding wheel?

Diamond grinding wheel description:

Diamond grinding wheel is the best abrasive tools for grinding hard alloy, ceramics,
Optical glass, gem and other stones, etc.
Diamond grinding wheel with high hardness and brittleness.
The diamond is easy to carbonization at 700 C ~800 C,
So it is not suitable for grinding steel which contains a lot of iron element.

CBN grinding wheel description:
CBN hardness is slightly lower than diamond,
But due to its thermal stability is good (1300 degrees ~1400, high temperature)
So it is not suitable for grinding steel.
CBN's thermal conductivity is around 46 times of corundum.
It has much longer service life than corundum grinding wheels.
So CBN is the best abrasive tools for grinding high hardness and toughness metal material like Hardened steel, bearing steel, high-speed tool steel, stainless steel, heat resistant steel and titanium alloy.

What grain size shall you choose?
For Diamond or CBN grinding wheel,150# is a medium rough grain size which can meet the needs of most usages of you have no special requirement, if you want to grind faster, choose a rougher grit,but it the surfacing result will be rougher at the same time, how to achieve the goal faster grinding and finer grit, choose two or three grit as a group, use rough grit grind first, then finer grit.
