Keyway milling cutter 22d8 22e8 what difference do I have? In a few days I need to do keyway, 22 (0, -0.04) and 22 (0.05). How do I choose the cutting tools?
22d8: between 22-0.068~-0.098; 22e8: between 22-0.04~-0.073. The width of the milling cutter is wider than the actual diameter of the milling cutter. It is OK to choose the cutter according to this principle.
The keyway. Nor is there much demand. The left and right sides will be overcast with. The upper and lower sides require excessive coordination.22 (0-0.04) means 22 keyway, you can only stay between 22-0 - 22-0.04. Practical tolerances...
From the milling cutter you gave, that is, the machining accuracy is different, and the specific difference depends on the specifications of your two milling cutters. For example, cut deep, what is the material?. Inlaid? Indexable? Or alloy of nature?
