The Tool Leaves Tracks at Places Where Cutting-in Starts or Where Lines Change Direction
Check Action
Is the spindle rotating speed too fast for
the feeding speed?
Try reducing the spindle rotating speed.
" P. 56 “Adjusting the Tool Feeding Speed and the Number of Rotations during
Engraving (Override)”
Is the tool worn? Replace the Tool.
An Engraved Bottom Surface Is Rough or Burring Remains
Check Action
Is the spindle rotating speed too slow
for the feeding speed?
Try increasing the spindle rotating speed or reducing the feeding speed.
" P. 56 “Adjusting the Tool Feeding Speed and the Number of Rotations during
Engraving (Override)”
Is the workpiece rmly secured in
place?
Reload the workpiece so that it does not come loose or slip.
" P. 38 "Step 1: Setting the Workpiece"
Is cutting-in performed only once? Try performing engraving a second time to nish the bottom surface and
remove any burring. Making the cutting-in depth about 0.02 to 0.05 mm
(0.0008 to 0.002 in.) deeper for the second pass may yield better results.
Is the tool worn? Replace the Tool.
Does the tool diameter match the collet
diameter?
If the collet diameter is too large for the tool diameter, engraving will be
performed without the tool rmly secured in place. Use a collet that ts
the diameter of the tool.
