2.Large cutting edge burr;Cutting speed is too high;

3.Improper feeding or machining allowance is too large;

4.Reamer main Angle is too large ;

5.Reamer bending ;Hinge on the cut

ting edge to the chip tumor;

6.The hinge cutting edge grinding of runout error;

7.Cutting fluid selection is not appropriate;
