Product Information

VT07 Series

The VT07 series can handle various materials from processing of hard-to-cut workpieces to edge trimming of silicon wafers

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 highload 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 such as silicon nitride.
Thanks to the enhanced bond line-up, this bond series also realizes processing in various fields, such as edge trimming of silicon wafers.

Experimental Data

Saphire processing
Compared to the existing blade, the VT07 blade can achieve a higher grade of processing for sapphire, which has an extremely high hardness.

Deep-groove processing
The current blade bends during deep-groove processing. The VT07 series (VC100 bond) can achieve highly straight processing results for deep-groove.

Edge trimming of silicon wafers
The wafer edge trimmed by the VT07 blade (VC200 bond) has the same quality realized by the resin blade processing.

Cautions during usage
Note the below points on its characteristics when using the vitrified bond.

1.	Since the VT07 series is nonconductive, contact setup (conductive type) can not be used.
2.	Since the VT07 series is nonconductive, contact setup (conductive type) can not be used.
3.	When using the VT07 series on a machine with the standard BBD (Blade Breakage Detector Unit), since there is a possibility of a wrong detection, use with the BBD function turned off.
4.	Since there is a fear of blade breakage, do not conduct the chopper cut setup (CCS) before dressing.
