The input range for the setting items are as follows:
Setting item Input range
Diameter ± 9999.999mm or ± 999.9999”
Number of divisions 2 to 360 divisions
Offset angle 0 to 359.9 degrees (unit: 0.1 degree)
IMPORTANT
• When using the bolt-hole circle machining function, the resolution for the X- and Y-axis
should be the same.
• If an error occurs in the KA counter, press the Cancel key to quit the bolt-hole circle
mode.
• After the bolt-hole circle machining is complete, the coordinate system returns to that of
the mode prior to the bolt-hole circle mode.
• Do not displace any axis scale during numeric entry. If displaced during entry for
presetting, etc., the scale unit may be damaged by an overrun.
• Even if the counter exceeds the counting range, Error 30 will not be displayed during
numeric entry. The error message will be displayed after numeric entry has been
completed.
• Do not displace any axis scale too much while numeric entry is being performed.
• When in inch mode, due to the setting of the counter, there may be cases where the
input range shall be ± 99.99999”.
• Performing the bolt-hole circle machining
Step 1 Position the tip of the drill at the center of the circle on the workpiece.
Step 2 Press the bolt-hole circle key. The diameter and the number of divisions are
recalled on the X-axis and Y-axis, respectively (already input values).
Step 3 While the “d” at the left end of the display is blinking, enter the diameter using the
ten-key and press the Load key. If using an auto-recalled value, only press the
Load key.
