5. Troubleshooting
Chipping Occurs (Edges of Milling Products Become Chipped)
Check Action Refer to
Is the installation base of the
machine secure?
The vibration from cutting can shake the installation base. —
Is the workpiece rmly secured in
place?
Check the mounting condition of the workpiece. Fasten the
workpiece in place securely so that it will not slip out of place
or come loose because of milling bur pressure or vibration
during milling.
—
Is the milling bur worn? If the same milling bur is used for milling for a long period
of time, it will become worn and aect milling results. Try
replacing the milling bur with a new one. The work time of the
milling bur can also be managed in VPanel.
—
Is the collet deformed? The collet may be deformed if the tip of the spindle strikes the
rotary axis, etc., or if the spindle is locked. Replace the collet
if it is deformed.
—
Is the thickness specied in the
milling data excessively thin?
If the workpiece thickness is excessively thin, chipping is likely
to occur. Check the shape specied in the milling data.
Are the milling conditions too
strict?
Strict milling conditions may aect milling results. Review the
CAM milling conditions.
A Hole Opens in the Milling Results
Check Action Refer to
Does the milling bur diameter match
the CAM settings?
Check the CAM's milling bur settings. —
Is the machine out of correction? The origin point may become out of position due to prolonged
use or relocating the machine, which can aect milling results.
Perform automatic correction. If the expected results cannot
be obtained even after performing automatic correction,
perform manual correction. With manual correction, changing
the Z value in the + direction in Origin point may improve the
situation.
—
Are the milling conditions too
strict?
Strict milling conditions may aect milling results. Review the
CAM milling conditions.
—
Is the thickness specied in the
milling data excessively thin?
The nish thickness of milled products needs to be 0.8 mm or
more. Check the thickness specied in the milling data.
