About Chamfering With Ball Bull End Mills Inventor Cam

Inventor CAM supports chamfering with ball end mills and bull end mills. This may be useful in cases where you are already using a ball or bull end mill in a part and wish to chamfer off sharp edges, but save a tool change to an ordinary chamfering tool. With small chamfer sizes, the differences between a flat chamfer using a chamfering tool and a slightly rounded chamfer may be negligibleUse PVC cement for a better seal and stronger hold. Find some actual lead balls to do the milling. Implement some sort of screen in the mouth to prevent the balls from falling out when emptying the mill. Create a mount so the mill can be stationed on a table while spinning. I would love to see you build a ball mill and make changes to my design.
