Turning a ball? Practical Machinist

2012-7-8  I have to machine a trailer hitch type ball and am very unfamiliar with using i and k values for radii. I intend to do it in two halves, the front half using an r value and a right hand turning tool then groove out the back site and finish it with a left hand tool in a +z direction. I know my absolute x,z start and end points but am having a hard

Ball Turning Tool Practical Machinist

2021-2-6  To generate a ball, the cutting tool has to pivot over a point that is directly under the center of the ball being cut. It seems that this attachment accomplishes that with no part of it ever being directly under the center of the ball. I would really like to see one of those in action! Thanks again. Jacques

Ball Turning with Manual Numerical Control, version 2.1

2018-8-23  This software tool will let you turn a ball that is attached to a shank. The user specifies the workpiece's initial diameter, finished ball diameter, finished shank diameter and the program guides you in the machining operations. This is done in three passes: outline turning, a roughing pass, and a

Lathe ball-turning, spherical surfaces, concave and

A ball turning attachment is really just a mechanism that cause the cutting edge to follow a circular path which is the outside of the ball being cut. There are two different ways this can be done. The cutting edge can turn in the horizontal plane or it can turn in a vertical plane lying along the axis of the lathe..

Turning a ball on a lathe The Hobby-Machinist

2013-1-13  Compare the two readings and adjust the cross slide until it reads "0" on both sides. Lock your cross slide from moving. If you don't get the fixture exactly on center, you will not turn a perfect ball or sphere. The roundness of the ball will be off. Oh, BTW- set your compound at 90 deg. to the cross slide and lock the gib in place.

Ball Turning with Manual Numerical Control, version 2.1

2018-8-23  This is done in three passes: outline turning, a roughing pass, and a finish pass. The outline turning reduces the workpiece's diameter to equal the roughing diameter of the ball and the roughing diameter of the shank. The roughing pass cuts steps almost as wide as your parting tool and about .01" away from the finished surface2. The work goes

Turning a ball on a lathe The Hobby-Machinist

2013-1-13  Many years ago I built a ball turning attachment to turn 3-3/4" and 4-3/4" diameter balls made of Delrin plastic. Anyway you do it, its a two operation job to turn a "round" ball. As one member stated above, your pivot point of your ball turning attachment has to be on "exact" center of the work you are about to turn a "ball" on.

2015-5-4  The first attempt at turning was a 1-1/2" ball from acrylic. I used a 1/2" tool bit from my collection, not attempting to grind a proper bit. The turning process went smoothly and was well controlled. It helps to tighten the clamp bolts lightly so there is a small amount of resistance. Do not overtighten as a jerky motion may result.

Obviously, the accuracy of the ball is going to be a real finicky thing if you care about that.
