9A3 Diamond & CBN grinding wheel

Specifications

1. 9A3 Diamond&CBN Grinding wheel

2.Application:

9A3 diamond grinding  wheel,  Used for sharpening and finishing of carbide tools, machining of glass, ceramic, quartz, semiconductors.The diamond layer is made of diamond grinding powder in resin bonds.

Tools coolant is required.

3. Specification

 4.Superhard cutting&grinding  tools:

Diamond and cubic boron nitride (CBN) are considered to be the hardest known grinding materials and are therefore
often referred to as “super-abrasives“. For this reason they are suitable for machining materials which are difficult or
even impossible to grind with conventional abrasives such as silicon carbide or corundum.

5. Basic application
Diamond CBNDue to its extreme hardness, Diamond is particularly suitable for machining the following
materials:
– All carbide metal grades
– Cermet
– Oxide and non-oxide ceramics
– PCD / PCB
– Hard facing alloys
– Sapphire, glass
– Ferrite
– Graphite
– Fiber reinforced synthetics
– Precious and semi-precious stones
CBN consists of the elements boron and nitrogen. In contrast
to Diamond, CBN has no carbon atoms, making it suitable
for machining steel. CBN is better suited for machining the
following materials:
– Hardened steel over approx. 54 HRc hardness
– High-speed steel (HSS)
– Stellite
– Nickel-based special alloys

6. Dressing
When a wheel is trued, the abrasive surface should be dressed to condition it for aggressive stock removal. The bond material should be eroded to expose the grit.
Dressing Sticks. Aluminum oxide dressing sticks are hand held on the surface of the grinding wheel until the wheel consumes
the dressing stick rapidly. The wheel is now ready.
