About conditioning
The term "conditioning" refers to the operations performed to dress a blade
contact surface of a hub mount or flange.
The contact surface accuracy of the flange A (rear flange) is particularly
important. The low accuracy of this surface gives an adverse effect on the
machining precision, which results in a tapered shaped cutting slot, an
excessive kerf width or a blade breakage.
WARNING
- For conditioning purposes, you have to operate the X-, Y- and Z-
axes while the cover is open with its interlock disabled by the
maintenance switch.
Conditioning must be carried out by the qualified maintenance
personnel who have a good understanding of safety precautions.
- If any unexpected machine operation is inadvertently invoked
during conditioning, the maintenance personnel may be injured.
While you don't use the touch panel, press the Disco's logo button
located at the upper left of the screen in order to lock up and
deactivate the touch panel.

2-1-1. Flange conditioning
Movement in flange A conditioning
When the flange type blade is used, the axis moves as illustrated below in the
flange A conditioning.
The first spark-out operation performed after Y-axis indexing always starts
from the inside of the flange.

Shape of the flange after conditioning
Conditioning is conducted so that the flange A end face will be highest at the
outer end and enclose the blade.
The shape of the flange after conditioning should be as illustrated below.
