Confirm 'BATTERY REPLACEMENT' accumulate time.

CAUTION: Do not rotate the spindle without a workpiece clamped in the chuck.

Is a well-balanced workpiece, as small in diameter as possible, clamped in the chuck with the usual chucking pressure?

Is the spindle warm-up performed below the maximum permissible rotation speed of the chuck, workpiece, and fixture?

Are the chuck, workpiece, fixture, and tool mounted securely before performing the spindle warm-up?

Is the rotary tool-spindle warm-up performed at or below the maximum permissible rotation speed of tool holder?

Is the tool to be mounted on the rotary tool-spindle a small diameter tool that can be rotated at the maximum spindle speed or more?

NOTE: Adjust the rotation speed for warm-up based on the maximum rotation speed for the machining programs used for the day.

Enter the rotation speed for warm-up

Sign off on the daily spindle warm-up
