BLADE PRECONDITIONING PROCEDURE

Our Dicing Blades are pre-dressed, therefore a long extensive procedure is not necessary. However, we recommend the following to retrue and condition every time it is first mounted on the saw spindle to improve the quality of cuts and to extend blade life.

Hub Blades - Can be dressed either dummy silicon wafer or dressing board.

In Silicon Wafer
4,5 or 9 Micron
grit size blade, cut at fixed table speed = 10mm/sec (or 0.39"/sec) and according to chart below.
