cnc rotating nut|Ballscrews & Supports : Clark I gather that the rotating nut design overcomes screw whip. Out of curiosity, are these ball screw nut drive mechanisms available (at a reasonable hobbyist cost)? If not, has anyone tried making one using the wheel bearing from a front wheel drive car?

cnc rotating nut,
In the rotating ballnut system the nut is spun and the ballscrew is kept stationary - the r. Let's talk about the design and build of a large cnc router/mill.Ballscrews & Supports Starting work on a 4' x 8' going to try out a rotating nut for the long axis due to whip and inertia concerns. Hopefully can get some feedback on the design. Wondering if anyone else has implemented this successfully. I do have access to a cnc bridgeport and decent lathe as well which i plan to use. Similar Threads: rotating patternIn a rotating ball nut assembly, the screw is stationary and the nut is rotated, typically by a motor that is attached to the nut via a belt and pulley system. Support for the ball nut is provided by a high-capacity radial bearing.
Has anyone made something using regular ball nuts and got it working? Just In Bobcad-Cam V25 Mill/Lathe/Plasma + tons of EXTRAS. CHEAP CHEAP CHEAP! I've never done that but it should be possible.

If not, has anyone tried making one using the wheel bearing from a front wheel drive car?Hiwin’s rotating nut utilizes a special end cap design that allows the steel balls to circulate inside the nut while featuring an integral bearing that allows the ballscrew shaft to be fixed. This unique design reduces noise generated at high speeds and offers higher axial loading and stiffness. My Bridgeport has a rotating nut for the Z axis. I understand your concerns about inertial effects on a long shaft and revolving the nut to compensate is a good idea. Thanks for sharing your results. I see the Y axis assembly has a lot .
This innovative ball nut is engineered for "active gantry" CNC machinery. In this type of setup, a stepper motor is mounted on the gantry plate to drive the rotating ball nut attached to the gantry plate, while the ball screw remains static(fixed) on the linear axis.
