of the drum. If the drum is too soft, it does not operate as
aggressively as it should. The drum can remove too much
wood in places where the fiber is softer and too little where
it is harder. Again, whether you are using a steel or rubber
drum, you need to make sure you are using the right abrasive.
As a general guideline, for example, if an operator wants to
remove 0.030-inch of material, it is recommended to begin by
calibrating operation with 80 grit abrasive.
3: Another tip is to adjust the speed of the conveyor.
When you slow down the conveyor speed, you give the abra-
sive more time to remove material on the part.
The solution in each quality situation is closely tied to
your investigation of the problem. If a part comes off the line
uneven or with stain absorption that’s not optimal, think it
though, consider these tips, make adjustments, and run the
calibration operation again. Good luck!

Maybe the task at hand is applying veneer to an MDF or
plywood board. Or maybe you need to make sure a cabinet
door that’s been glued is perfectly flat. Either way, achieving
perfect thickness all over the part depends on several factors
being precisely right. If you experience problems with sanding and finishing, here are some tips that could solve them.
1: It’s crucial to use the right abrasive. Problems can arise
if you use too fine a grit and remove too much of the wood
material as the abrasive spins around the drum. At the end of
the process, you will see that your part is uneven. You might
also notice a depression in the wood fiber, which impacts the
way the stain or sealer absorbs and causes color inconsistency.
2: Your problem could also be related to the hardness
