8.5 Spindle Velocity
The speed of the spindle rotation can be varied for different purposes.
8.5.1 Reduced Height Velocity
When the blade descends to the NCHD, it creates "mist" between the
prisms due to high-speed spindle rotation. This phenomenon reduces the
NCH accuracy, or prevents the photoelectric cell from properly registering
the moment when the blade crosses the ray. The Reduced Height
Velocity parameter is intended to solve this problem.
Once the Reduced Height Velocity parameter is defined, the system
automatically reduces the revolting speed when performing the height
procedure.
To Set the Reduced Height Velocity Parameter
1 Click to open the Workbook Workspace
2Select Setup and diagnostics > Saw > Dicer.
3 Under Dicer parameters, locate the Use Reduced Height Velocity
parameter and set it to "Yes".
4 Locate the Reduced Height Velocity parameter and set it to 7000.
Note: This feature is intended for 4” systems only.
Note: Advanced Dicing Technologies Ltd. recommends the Reduced Height
Velocity value falling between 6000 rpm and 8000 rpm as optimal.
