2-2-3. Executing conditioning

Procedures for executing conditioning

WARNING

- When you adjust the conditioning jig setup position or set the

conditioning jigs, you have to disable the axis driver power supply

shutoff feature with the maintenance key and operate the X-, Y- and

Z-axes with the splash cover open. If your fingers or hands are

positioned in the drive section or under the spindle, they may be

caught or cut off.

Do not place your fingers or hands in the drive section or under the

spindle.

- For conditioning jig setup purposes, the axes can be operated with

the touch panel manual buttons even if the splash cover is open.

The maintenance personnel could be injured by an inadvertently

invoked unexpected machine operation.

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.

- If the person other than the maintenance personnel touches the

machine, the machine operates and the maintenance personnel

may be injured.

Ensure that no person other than the maintenance personnel

touches the machine.

- If the spindle rotating speed is unduly high for the employed flange

diameter, spindle galling or flange separation may take place to

incur serious personal injury or death.

Before conducting conditioning, be sure to verify that the speed

rotating speed is appropriate for the flange diameter.

The maximum permissible spindle rotating speed is as follows:

60,000 min

-1

(60,000 rpm) for 2-inch blade

CAUTION

When the conditioning operation is started, the X-axis moves to the

rear side of the machine. Depending on the position of the

conditioning jigs, they may hit the wheel cover nozzle during

conditioning.

Before starting conditioning operation, make sure that the wheel

cover nozzle does not collide against the conditioning jigs.

NOTICE

If splash cover opening is carried out without rotating the

maintenance switch, no axis is operative. It also makes it necessary

to effect system initialization after splash cover closure.

Step No. Do This

(Continued from the previous section)

Insert the maintenance key into the maintenance switch. The

maintenance key is placed under maintenance personnel control.

Maintenance switch

Rotate the maintenance key clockwise and placed in the

OVERRIDE position.

While pressing the override button, open the splash cover.

Override button

control the touch panel with standing at the normal working

position.
