When reaming with carbide reamer, there will be a spiral mark on the hole wall. What's the problem?
It depends on what material you are working on.
With spiral reamer and / or reduced single feed of reamer / try to increase the rigidity of the hinge handle, the spiral grain should be eliminated
How many spirals do you have?Also, send out your parameters and the current process!!There are many factors that affect spiral lines!!
