Edge Wheel for Silicon Wafer Grinding

The unrounded silicon wafer is mounted onto a grinding chuck and a profile rounding wheel rounds the edge of the wafer. Metal bond wheels and resin bond wheels are used in edge grinding on the outer circumference of sillicon wafers, which requires uniform sharpness in addition to precision accuracy in the shape of the wheel and abrasion resistance.

 

 

Both outer-circumference machining and notch machining wheels are available in three types: single-groove, multi-groove, and composite rough finishing

 

Application of edge grinding wheel
Edge grinding wheel, chamfering wheels for sapphire substrate, silicon carbide substrate and silicon wafer, liquid crystal panel, ITO glass, PDP glass, quartz glass, microcrystalline glass, photovoltaic glass, automotive glass.  A small diamterer wheel for notch grinding.

 

 

Features of edge diamond wheel for silicon and sapphire wafer
- Grinded with uniform chamfer width, excellent rigidity
- Strong groove shape retention, long life
- By edge grinding the final diameter is adjusted
- A uniform diamond layer minimizes machining damage
- Highly precise slotted shape support various wafer shapes

 

The specification of edge grinding wheels
D (mm) T Grit bonded Groove
50 - 250 3 - 20 325 - 3000# Metal / resin 1-10G
Other size can be designed according to customers' requirement
