Some of the main disadvantages of climb cutting are: Excessive Vibrations. When dealing with thicker pieces or at faster feed rates, you'll experience severe vibrations because of the tool's impact on the workpiece. These excessive vibrations can cause multiple problems including tool deflection and damage. As a result, the overall accuracy ...
