A Morse Taper Removal Clamp

摘要

The normal practice to remove cutters which have Morse tapers from the spindle of a milling machine is to undo the drawbar by 2 or 3 turns and hit the end of the drawbar with a mallet. A gentle tap is all that is normally required, but sometimes the cutter is firmly wedged into the spindle after making heavy cuts and requires a much larger whack. This practice makes me cringe every time I do it and cannot be any good for the drawbar thread or the spindle bearings.There are designs for attachments which mount on top of the mill spindle that push the drawbar to release the cutters from the spindle but these are not suitable for my SX3 mill. The spindle on my mill retracts completely into the drive head and I would not like to reduce the amount of contact with the driving spline.
