Applications: Si3N4, Crystal, Sapphire, etc
This bond series employs a vitrified bond that has been difficult to manufacture into thin blades so far. These blades can process with an acute degree of straightness and dimensional accuracy for high-load processing by using the excellent rigidity and cutting ability of the vitrified bond. As a result, VT07 realizes quality processing for difficult-to-cut materials. Thanks to the enhanced bond line-up, this bond series also realizes processing in various fields, such as edge trimming of silicon wafers.
|Bond name||Major applications|
|VT07||VC100||For processing under high load or of hard-to-process materials (e.g., sapphire, silicon or deep groove processing)|
|VC200||For edge trimming (silicon)|
Compared to the existing blade, the VT07 blade can achieve a higher grade of processing for sapphire, which has an extremely high hardness.
|Workpiece||Sapphire 0.7 mmt|
|Spindle revolution||15,000 min-1|
|Size||56 x 0.3 x 40 mm|
The wafer edge trimmed by the VT07 blade (VC200 bond) has the same quality realized by the resin blade processing.
|Blade size||58 x 1 x 40 mm|
|Feed rate||5 degree/s|
|Depth||0.5 mm into Si wafer|
|Spindle revolution||Vitrified bond 20,000 min-1
Resin/Metal bond 30,000 min-1
Note the below points on its characteristics when using the vitrified bond.
