Common Cutting Problems
Snipe
When a workpiece is not properly supported as it enters or leaves the
machine, the ends of the workpiece will have more materials removed than
the rest of the section. To mitigate this problem, hold the workpiece up
slightly as it enters and leaves the machine. Sometimes, a small amount of
snipe is inevitable. The best way to fully eliminate snipe is to prepare a
workpiece with extra length, and then trim the ends when planing is done.
Chipping
Happens when cutting against the grain direction. See “
Select Feed
Direction
” in this section. For highly figured lumber and areas near a knot,
some amount of chipping is normal. In this case, moistening the problematic
area before planing can sometimes mitigate the issue.
Chipping can also cause by dirty or dull cutters. If chipping happens while
planing straight grain stocks, inspect cutter inserts and remove all resin
buildups. Rotate/replace dull cutter inserts when they are dull.
Indentation
This can happen when some foreign object is pressed on the workpiece when it passes through the planer.
Remove all resin buildups from the rollers, cutterhead, and table. Also, check the dust collection system
and ensure all wood chips generated are effectively removed.
Fuzzy Grain
Can happen when planing wood with high moisture content or if the cutter is dull. Sometimes this is
unavoidable due to the nature of certain wood types. To mitigate this issue, avoid using wood with high
moisture content and use sharp cutters.
